4. Motivation.
Diseases of the leg veins are still one of the leading causes of disability and disability. In the
United States and Western Europe, the frequency of varicose veins is 25%. In Russia, various
forms of varicose disease affects more than 30 million people, 15% of which are trophic
disorders. Today, for varicose veins are characterized not only is the number of cases, but
also to the appearance of varicose veins trend in young adults.
Deep vein thrombosis and pulmonary embolism may be concomitant to meet a doctor in any
specialty. Diagnosis and treatment of vein diseases often cause difficulties and baffled doctor.
The ability of a general practitioner to diagnose, provide the necessary assistance and be
treated effectively early in the disease of the lower limb veins is of great importance in
preventing complications.
Putting into practice the new modern methods of investigation and a deeper knowledge of the
pathogenesis of venous diseases can significantly increase the effectiveness of treatment.
5. Interdisciplinary communication and vnutripredmetnye. Anatomy, pathological anatomy,
pathophysiology.
Blood flow to the lower extremities by the veins of three types: superficial, deep and
perforating (communicating).
1. Superficial veins are systems of the great saphenous and small saphenous veins.
• Large subcutaneous Vienna originates in the medial malleolus, runs along the anteromedial
surface of the feet and empties into the femoral vein at the level of the oval fossa.
• Small subcutaneous Vienna begins at the lateral border of the foot near the lateral malleolus
and empties into the popliteal vein between the heads of the gastrocnemius muscle.
2. Deep veins - thin-walled blood vessels that accompany the artery of the same name in pairs
and their major branches, represented by systems of veins of the foot, shin, thigh and iliac
veins. Venous network triceps legs consist of calf veins draining into the popliteal vein, and
soleus veins draining into the posterior tibial and fibular veins.
3. Perforating (communicating) veins connect the superficial and deep venous network
among themselves. On these vessels the blood is sent from the superficial veins into the deep.
In the thigh are usually 2.1 perforating veins, and the rest are located on the lower leg.
For venous plexus characterized by the presence and abundance of connections between
different systems of veins, which provide great opportunities for the development of
collateral blood outflow tract in occlusion of the main veins.
6
Physiology
All leg veins are equipped with folding flaps, which provide blood flow in one direction:
from the superficial veins - in the deep, from the distal sites - to proximal. Under the
influence of retrograde flow valve closes, which contributes to the centripetal advance and
protect the blood capillaries and venules by a sharp increase in pressure at the time of the
muscle pump. When a person is, the hydrostatic pressure of the blood makes it difficult to
venous outflow from the lower extremities. However, any reduction in the hip and thigh
muscles drives blood through the veins in the proximal direction, and the venous valves, as
discussed above, preventing retrograde blood flow. This mechanism is called the musclevenous pump or "peripheral heart". Full leaf valves are durable and can withstand pressures
up to 3 atm. While walking the pressure in the veins of legs is reduced by more than twice.
All veins carry blood flow from the muscles, are equipped with valves. There are no valves
hollow veins, portal vein, the veins of the liver, lungs and brain veins.
The transition from a prone position to standing position leads to increased hydrostatic
pressure in the veins of the lower extremities. However, in the arteries of the hydrostatic
pressure increases in the same range. Therefore, the change in body position is not
accompanied by changes in the ratio of pressure in the veins and arteries at the appropriate
levels.
Above the inguinal ligament deoxygenated blood goes to the heart through the breath the
diaphragm and the difference between intraabdominal and intrathoracic pressure.
Pathological and pathophysiological basis of varicose veins
Most varicose happening in the great saphenous vein, at least in the short saphenous and
tributaries of the stem begins with the veins in the calf. So why do veins suddenly begin to
expand?
The main reason for developing varicose leg veins, is that of the venous wall is not muscle
tissue, which could provide the tone of blood vessels and promote blood in the right
direction, that is, to the heart. On the contrary, in the arteries of the muscular layer is,
therefore, a disease like varicose veins of the arteries, does not exist.
Vienna pushes the blood through valves through which blood can only move in one direction.
Promotion of blood through the veins also contribute to the leg muscles, the fibers are located
and veins. Muscle motion contributes to a better blood flow to the legs.
When sedentary muscles are not able to fully compress the veins and to ensure normal blood
flow. At this point, and is stretching thin vein wall. Blood collects in the veins of the weakest
areas, expanding and stretching them to the state of varices.
Pathological anatomy. At the beginning of the disease is hypertrophy and growth of cellular
elements, resulting in significant thickening of the vein wall. In the future along with
hypertrophy of the muscular elements is their loss of connection with the further propagation
of the cells. Venous wall tension resulting from the death of muscle cells of subcutaneous
7
veins, stimulates production of collagen by fibroblasts. Neural elements located in the wall of
the veins are in the process again and create a new negative factor leading to loss of function
of smooth muscles of the venous wall - atony. The wall of varicose veins abruptly thickens,
but it is uneven thickening and thinning alternating with large walls in some places. Vienna is
extended, is tortuous, it formed multiple protrusions, sometimes reaching a diameter of 2-3
cm In addition, the vast majority of patients (85%) with varicose veins of the lower
extremities have a pronounced lack of valves around the trunk of the great saphenous vein.
Deterioration of blood flow through the veins leads to malnutrition of the skin and
subcutaneous tissue, which is manifested on the skin the appearance of dark brown spots, and
then venous ulcers.
Physiopathology. The pressure in the veins of the lower extremities varies significantly with
changes in body position during movement. In the initial stages of varicose veins, where there
are no signs of failure of valves, venous pressure determined by the vertical position of the
patient, in line with normal numbers - 75-120 mm water column In the further course of the
disease, and especially when there are signs of valvular insufficiency in varicose veins the
pressure increases to 500-800 mm water column and more. Increased venous pressure in
superficial veins leading to the further unfolding of the physiologically inactive precapillary
arteriovenous anastomoses through which resets the arterial blood in the veins, which in turn
further increases venous pressure. In the standing position and walking in these patients arises
violation of the outflow of blood from the veins of the lower extremities, congestion in the
veins of the number to 500-1000, or even 2000 ml. The pressure in the veins of the legs and
feet can be higher blood pressure. This leads to difficulties of transition from the blood
capillaries of the skin and subcutaneous tissue in the venules and veins with the development
of stasis in the arterioles and capillaries, and the transition of the liquid part of blood into the
tissues, skin and subcutaneous tissue with subsequent development of trophic changes in the
legs and feet.
6. The order of activities:
6.1 The theoretical part;
Research Methods
1. Duplex ultrasound. Use sensors with a frequency of 4 MHz radiation and 8 MHz to
combine study with Doppler imaging of blood vessels. Access to any study of the deep veins
below the iliac crest. In the diagnosis of deep vein thrombosis duplex ultrasound is the
method of choice and gradually replacing phlebography. Signs of a blood clot: intractability
wall veins, increased echogenicity compared with the moving blood, the lack of blood flow in
the affected segment. Duplex ultrasound to differentiate fresh thrombus from growing old
organized. Study of iliac vein is often difficult due to gas accumulation in the intestine. The
diagnostic accuracy of the method is 95%, sensitivity - 94%.
2. Doppler study can confirm the presence of venous flow, to register changes in blood flow
during the phases of the respiratory cycle, an increase in blood flow during compression of
8
the leg distal to the test segment, the appearance of retrograde flow during compression of the
leg proximal to the test segment. The method is simple and often used in the diagnosis of
deep venous thrombosis and insufficiency of venous valves, but requires high skills of the
researcher.
3. Plethysmography to determine changes in the volume of the limb.
i. Impedance plethysmography. The method is based registration of the total electrical
resistance, which reflects blood flow to the limb. Impedance plethysmography - a highly
sensitive method for diagnosis of obstruction of the iliac, femoral and popliteal veins.
However, any state, accompanied by an increase in venous pressure (postromboflebitichesky
syndrome, heart failure, mechanical ventilation) increases the number of false positive
results. With partial occlusion of the vein, double leg veins and local calf vein thrombosis
may be false negative results.
ii. Photoplethysmography is based on recording the optical density of the skin, which
depends on its blood supply. The volume of blood in the vessels of the skin is greater the
higher the pressure in the superficial veins. The rapid filling of superficial veins after exercise
indicates failure of venous valves. Failure of venous valves can be quantified - to reduce the
filling time previously emptied veins. Or a pneumatic tourniquet cuff to recompress the
superficial veins can distinguish an isolated insufficiency of valves of superficial veins of
insolvency valvular deep veins.
iii. When mechanical plethysmography study segment extremity is placed in a sealed
vessel, and the fluctuations in recorded using hydraulic or pneumatic transmission. Evaluate
changes in blood flow during the phases of the respiratory cycle and after compression of the
limb cuff. The method used in the diagnosis of deep vein thrombosis trunk.
. Flebotonometriya. Measurement of venous pressure by catheterization of a vein of the
foot performed at rest and after exercise. The method is considered the reference to
quantification of valvular insufficiency of functional veins. Nevertheless, it has significantly
pushed the noninvasive tests such as photoplethysmography. For suspected iliac vein
obstruction measure the pressure in the femoral vein.
5. Scintigraphy with 125I-fibrinogen based on the inclusion of radioactive iodine in the blood
clot. The method gives satisfactory results only at the stage of active growth and formation of
thrombus and can not distinguish thrombosis from phlebitis. In addition, because of high
background radioactivity in it malospetsifichen vein thrombosis of the upper thigh and pelvis.
If you use drugs fibrinogen is always the risk of transmission of viral infections.
6. Venography - a common standard method for studying diseases of the veins.
1) Ascending venography. Rentgenkontrastnoe substance injected into one of the distal veins
and get the image of proximal venous network. Thrombi appear as filling defects are
rounded. The absence of staining for visualization of arterial venous collaterals of the set another sign of venous thrombosis.
9
2) The descending phlebography. Radiopaque substance injected into the femoral vein.
Retrograde spread of contrast medium to evaluate the degree of venous insufficiency:
I st. Slight reflux during the Valsalva maneuver.
II with Art. Antegrade blood flow in the iliac venous segment reflux to the distal femur.
III Art. Reflux through the popliteal vein to vein leg.
IV with Art. Landslide reflux venous leg up, antegrade blood flow in the iliac segment is
missing.
7. Function tests can detect failure valve surface and perforating veins, patency and
functional status of the deep veins of the lower extremities.
Sample Brodie-Trendelenburg Troyanov is designed to detect valvular insufficiency of
superficial veins. For her performance in patients in the supine position to raise the
investigated limb emptying varicose superficial veins. Next, place the confluence of the great
saphenous vein in the thigh pressed with your finger or on the upper third of thigh tourniquet
impose. The patient is on his feet. After a while the tourniquet is removed, and the varicose
veins collapsed on top quickly and tightly filled with reverse flow of blood. This is a positive
test, indicating the lack of valvular mouth of the barrel and the great saphenous vein. With a
negative result of the superficial veins quickly (within 5-10 s) filled with blood prior to
removal of the compression in the oval fossa, and their content is not increased by removal of
compression.
Sample Pratt - the most commonly used test to detect failure of perforating veins. In the
patient lying down after emptying of varicose veins in the upper thigh rubber band is applied,
compressing a large subcutaneous vein. Then the limb imposed crepe bandage from the toes
up to the tow, and the patient is on his feet. Crepe bandage starting to take off the top, turn
over a loop. When the formed between the tourniquet and bandage in 10 - 15 cm above
impose a second crepe bandage, which gradually encircle limb down after contracting rounds
first bandage. The appearance of a busy segment of the varicose veins between the two
bandages indicates failure valvular perforating veins through which is filled from the deep
venous network of the segment saphenous vein.
Sample Barrow-Cooper-Sheinis or trehzhgutovaya sample based on the same principle as the
sample Pratt. To impose a three investigated limb tourniquet: the upper thigh, above knee and
below knee. Filling the segment between the bundles of the superficial veins in the transfer of
a patient in a vertical position indicates the failure of perforating veins in this segment. The
displacement of wire harnesses to meet each other can be more precisely determine the
localization of perforating veins untenable.
Sample Mayo Pratt - the most common test for detecting and evaluating cross-functional state
of the deep veins. The patient is in a horizontal position to impose a rubber band the top third
of the thigh. Then this finite tight bandage crepe bandage from the toes to the upper thigh.
Patient walks 20-30 minutes. If the trouble and pain it does not, then it shows good patency
10
of deep veins, and, conversely, the appearance of arching pain in the shin alleges a violation
of patency of deep veins.
Sample Delbe-Perthes. In the upright position at the maximum filling of superficial veins on
the upper third of thigh tourniquet impose. Then the patient walks for 5-10 minutes. Rapid (12 min), emptying of superficial veins indicates good patency of deep venous valvular and
usefulness of perforating veins. If walking does not decrease the superficial veins, and,
conversely, their content increases, there are arching pain, it indicates the deep venous system
obstruction.
Special methods of diagnosis.
Before proceeding to the treatment of varicose veins doctor should make a very clear idea
about the state of deep and perforating veins of the limb. To date, no one can leave the patient
without Phlebology ultrasound. It is this study, non-invasive, highly informative in
experienced hands, a short time and quite burdensome for the patient, was the main diagnosis
in venous insufficiency. The most modern technique is duplex scanning with color Doppler
mapping, which allows to identify and cross-state valves of deep veins, from tibia to the
inferior vena, the direction of blood flow in the perforating and superficial veins. After the
widespread introduction of ultrasound techniques in practice the role of classical venography
greatly diminished. Today this technique is used infrequently, mainly in need of
reconstructive surgery (shunt or plastic) on the deep veins of the legs, and that every year the
frequency is reduced by venography performed learning and improving opportunities for
ultrasound.

Classification of venous disorders of lower limbs
A general classification of venous diseases not currently exist. Many of the proposed
classification [Kuzin MI, Vasyutka VJ, 1966 Askerkhanov RP, 1969 Klioner LI, 1969,
Saveliev VS et al, 1972; Klimov, VN et al, 1979; Shalimov AA, Sukharev II, 1984] reflect
some aspects of the pathological process in acute and chronic diseases of various levels of the
venous system. VI Bourakovsky and LA Bokeria (1989) proposed a generic classification in
which the entire venous system is divided into two parts - the system of the superior vena
cava and its main tributaries and the inferior vena cava system.
With regard to the inferior vena cava and its main tributaries, the disease of which differ
considerably large number of occurrences, the most common pathology in the range of the
venous system is a varicose superficial veins of the lower extremity with the most likely
outcome in chronic venous insufficiency. Another very common disease of the inferior vena
cava thrombosis are acute. The latter have a tendency to transform into
postromboflebitichesky syndrome (PTFS) - a chronic stage. At the same time are affected and
the deep and superficial segments of the system, which again leads to the development of
chronic venous insufficiency of the lower extremities. In addition, acute thrombosis of deep
inferior vena cava system in some cases can cause serious complications, which primarily
include pulmonary embolism and venous gangrene, so-called blue flegmaziya.
Treatment. Existing methods for treating varicose veins of the lower extremities can be
divided into four groups: 1) conservative and 2) sclerosing (injection), 3) surgical and 4)
combined. Surgery is indicated in cases where the primary varicose veins is accompanied by
chronic venous insufficiency, and with symptoms of circulatory disorders and lower
extremity varicose accession to various complications - eczema, dermatitis, ulcers, varicose
veins thrombophlebitis.
Control questions:
1. anatomical features of the veins of the lower extremity.
2. mechanism of the musculo-venous pump.
3. Varicose leg veins.
4. Thrombophlebitis of veins.
5. Postromboflebitichesky syndrome
6. chronic venous nedostatochnocht.
7. Syndrome Pedzhetta-Shrettera (acute subclavian vein thrombosis)
8. superior vena cava syndrome.
The answers to these questions:
13
1. Blood flow to the lower extremities by the veins of three types: superficial, deep and
perforatnym (communicating).
1. Superficial veins
and. Large subcutaneous Vienna originates in the medial malleolus, runs along the
anteromedial surface of the feet and empties into the femoral vein at the level of the oval
fossa.
b. Small subcutaneous Vienna starts at the lateral margin of the foot near the lateral malleolus
and runs into the popliteal vein between the heads of the gastrocnemius muscle.
2. Deep veins - thin-walled blood vessels that accompany the artery of the same name in pairs
and their major branches. Venous network triceps legs consist of calf veins draining into the
popliteal vein, and soleus veins draining into the posterior tibial and fibular veins.
3. Perforating veins connect the superficial and deep venous network among themselves. On
these vessels the blood is sent from the superficial veins into the deep. In the thigh are usually
2.1 perforating veins, and the rest are located on the lower leg.
2. All leg veins are equipped with folding flaps, which provide blood flow in one direction:
from the superficial veins - in the deep, from the distal sites - to proximal. When a person is,
the hydrostatic pressure of the blood makes it difficult to venous outflow from the lower
extremities. However, any reduction in the hip and thigh muscles drives blood through the
veins in the proximal direction, and the venous valves prevent the retrograde flow of blood.
This mechanism is called the muscle-venous pump or "peripheral heart". Above the inguinal
ligament deoxygenated blood goes to the heart through the breath the diaphragm and the
difference between intraabdominal and intrathoracic pressure.
3. "Varicose" is derived from the Latin. "Varix, varicis" - bloating. When the disease is
swelling of the subcutaneous veins, impaired outflow of blood on them with the development
of congestive changes in the lower extremities. Varicose veins are characterized by the
appearance feet saccular protrusion - varicose veins, tortuosity and increase in the length of
the surface of leg veins.
1. Primary varicose veins - the most common disease of the leg veins, occurs in 10-20% of
the population. The main reason, apparently, is a hereditary connective tissue weakness and
educated her vein walls and valves of venous valves. Risk factors: family history, profession,
associated with prolonged stay on his feet, pregnancy, age-related changes; obesity.
2. Secondary varicose veins due to increased venous pressure.
4. Thrombophlebitis - inflammation of the vein wall, accompanied by the formation of a
blood clot in the lumen of her. May be affected by any superficial Vienna. The main
complaint - the pain, along the vein is palpated a painful cord tight. To eliminate the
associated deep vein thrombosis are shown non-invasive study. Deep vein patency was
14
determined by non-invasive methods (duplex ultrasonography, Doppler study) rarely used
phlebography. For the differential diagnosis is used:
1. A sample of the Trendelenburg
2. Photoplethysmography. Superficial veins are pinched or pneumatic tourniquet cuff: an
increase in venous filling time means that only affected the subcutaneous veins.
5. Postromboflebitichesky syndrome develops after suffering deep vein thrombosis and is
characterized by failure of venous valves and occasionally - a violation of the venous
outflow. Small clots can completely dissolve under the action of the fibrinolytic system of
blood. But more is organizing a blood clot, that is, its replacement by connective tissue and
sewerage - germination thrombus capillaries. As a result, cross-veins is restored. However,
this process is accompanied by damage to the valves of venous valves, leading to their
inferiority. As a result, disturbed function of musculo-venous pump and develops a persistent
increase in venous pressure.
6. Chronic venous insufficiency develops in varicose veins or postthrombophlebitic diseases
of the lower extremities. Despite the similarity of many of the clinical symptoms, especially
edema syndrome manifestations in these diseases are different.
7. Development of the disease contribute to the topographic features of the subclavian vein,
located in the circumference of the bone and tendon-muscle formation. With strong stresses
the shoulder girdle muscles, combined with the movements of the shoulder joint, eliminates
the subclavian space and Vienna is squeezed between the clavicle and a rib.
8. A group of symptoms arising from impaired blood flow in the trunk of the superior vena
cava and venous hypertension caused by regional upper body is called "the superior vena
cava syndrome." According to the literature men suffer 3-4 times more often than women.
6.2. The analytical part.
The case dealt with the problem consistently, emphasizing the diagnostic and tactical features
in a particular case.
situational problems
Problem number 1.
Patient 65, a number of years suffering from BPB lower extremities. 3 days ago there was
pain along the posteromedial veins of the left tibia. Morbidity increased, the patient began to
experience difficulty in moving, the temperature rose to 37.8 * C. On examination, along the
vein is determined by the sudden flushing. Vienna thickened, sometimes chetkiobraznaya,
palpable in the form of a sharply painful pinch. The skin around a few infiltrated, hyperemic
and painful. Swelling in the foot and lower leg almost none.

Interactive game "question ball"
Write questions about the little pieces of paper and stick on the ball with a ribbon molding so
that it is possible to read the questions completely and remove the following response.
Throws the ball to one of the students. A student who receives the ball detaches one of the
questions and answers the question written on a piece of paper. If the answer is correct the
game continues and the student who answered the question, throws the ball to another
student. Thus, the game continues until you have answers to all questions.
Questions and answers:
1. - The value of duplex ultrasound in the diagnosis of venous diseases of lower limbs.
Use sensors with a frequency of radiation 4 and 8 MHz to combine study with Doppler
imaging of blood vessels. Access to any study of the deep veins below the iliac crest. In the
diagnosis of deep vein thrombosis duplex ultrasound is the method of choice and gradually
replacing phlebography. Signs of a blood clot: intractability wall veins, increased
echogenicity compared with the moving blood, the lack of blood flow in the affected
segment. Duplex ultrasound to differentiate fresh thrombus from growing old organized.
Study of iliac vein is often difficult due to gas accumulation in the intestine. The diagnostic
accuracy of the method is 95%, sensitivity - 94%.
2. Venous malformations
A venous malformations - a relatively rare and heterogeneous group of diseases, including
aplasia, hypoplasia, a doubling of the veins and the presence of vestigial veins. Congenital
diseases of veins can be combined with arteriovenous malformations.
B. Klippel-Trenaunay syndrome - a congenital disease of the major veins. Characterized by a
triad of signs: a vascular nevus, congenital varicose veins, soft tissue hypertrophy of one or
more limbs. In addition, common hypoplasia or absence of deep vein thrombosis and,
consequently, the secondary increase in venous pressure. Develop a network of collaterals
around the missing segment of the vein can lead to the formation of large thin-walled varices
in the pelvic veins, which often are the cause of rectal and vaginal bleeding. To eliminate the
18
need angiography arteriovenous malformation. Treatment is conservative: the exalted
position of the legs, wearing elastic stockings.
3. Pulmonary embolism.
One of the serious complications of deep vein thrombosis of lower extremities is a pulmonary
embolism (PE). Clinically observed sudden severe chest pain, shortness of breath and
tsianogz (face, neck, upper half of the thorax), lower blood pressure. In cases of hemoptysis
associated infavrkta light, the temperature rises.
In the treatment of heparin administered in large doses (30-50 thousand units.) Selectively
into the pulmonary artery or intravenously streptazu (500 thousand-1 million. ED), avelizin
(250 thousand - 1.5 million units per day). Occasionally, emergency surgery is shown, the
pulmonary artery embolectomy.
4. Methods venography
Venography - a common standard method for studying diseases of the veins.
and. Rising phlebography. Radiopaque substance injected into one of the distal veins and get
the image of proximal venous network. Thrombi appear as filling defects are rounded. The
absence of staining for visualization of arterial venous collaterals of the set - another sign of
venous thrombosis.
b. Descending phlebography. Radiopaque substance injected into the femoral vein.
Retrograde spread of contrast medium to evaluate the degree of venous insufficiency:
1) Slight reflux during the Valsalva maneuver.
2) anterograde venous blood flow in the iliac segment reflux to the distal femur.
3) reflux in popliteal vein to vein leg.
4) to venous reflux landslide tibia; anterograde blood flow in the iliac segment is missing.
5. Treatments for varicose veins varikonogo limb
1. Conservative: the sublime position of the feet, wearing stockings, creating a pressure
gradient from foot to thigh. These measures are most effective when postflebiticheskom
syndrome, varicose veins, caused congenital arteriovenous malformation.
2. Sclerotherapy is used to remove small varicose veins and residual varicose after surgery.
3. Surgery. The most frequent indication for surgery - removal of a cosmetic defect feet.
Other indications: failure of conservative therapy, continuous pain, complications (bleeding,
ulcers, thrombophlebitis of superficial veins). Acquired arteriovenous fistulas also require
surgical intervention
6.Tromboz deep vein
19
A. Incidence. Deep vein thrombosis is often asymptomatic and go unrecognized, so that the
overall incidence of disease is unknown. According scintigraphy with 125I-fibrinogen, deep
vein thrombosis complicating the postoperative period in 30% of patients older than 40 years.
Deep vein thrombosis is diagnosed in more than half of patients with paralysis of lower limbs
and more than half of patients, long-term bedridden.
B. Etiology and pathogenesis. The main causes of deep vein thrombosis coincide with
thrombotic pathogenetic factors (Virchow's triad):
1) endothelial damage;
2) slowing of venous flow;
3) increased blood clotting.
Risk factors include heart failure, advanced age, malignancy, trauma, obesity, prolonged
immobilization of the limb, prolonged bed rest, oral contraceptives, erythremia,
thrombocytosis
7. What are the contraindications for phlebectomy.
Contraindications to the removal of saphenous veins: limb arterial insufficiency, pregnancy,
infections of skin and soft tissues, lymphedema, hemorrhagic diathesis, a high anesthetic risk,
as well as thrombotic occlusion of the main deep veins and deep vein hypoplasia. Major
complications: hematoma formation and ecchymosis, subcutaneous, or damage to the sural
nerve, necrosis of wound edges and long nezazhivlenie. Known erroneous ligation and
removal of the femoral artery and femoral vein.
8. thrombosis prophylaxis
Prevention of thrombosis is important because it saves the patients with deep vein thrombosis
of lower extremities from serious complications such as pulmonary embolism and
posttromboflebetichesky syndrome. The need for measures to prevent thrombosis is greatest
in elderly patients, patients with severe diseases of the cardiovascular system in the
postoperative period. Specified quota of patients should be prescribed drugs which improve
blood rheology and microcirculation, which have inhibitory effects on adhesively-aggregative
function of platelets, reducing the potential for coagulation of blood. Non-specific prevention
of thrombosis: limb bandaging elastic bandages, electrical muscle stimulation shins,
gymnastic exercises, which improve the venous outflow, getting up early in the postoperative
period, prompt correction of fluid and electrolyte disturbances, anemia, removal, control of
the cardiovascular and respiratory disorders.
