Lymphatic system( tissues and vessels)
• The
lymphatic system filters and collects
lymph and large molecules in the
interstitial space that come from the
intravascular space.
• unidirectional
• Consists
flow and no circulation.

Lymph node, thymus, spleen and nodules
•
Lymph vessels

Right lymphatic duct and Thoracic duct

Lymphedema
• Lymphedema is
an abnormal accumulation
of high-protein concentrated fluid, usually
in the arms and legs.
• Lymphedema
is described as an abnormal
collection of protein, edema, fibrosis and
chronic inflammation.
Risk Factor (Secondary): Surgery
• Any
surgery that dissects or removes lymph nodes
increases the risk of lymphedema by impairing the lymph
flow.
• Common cancers
that may require surgical alterations of
the lymph nodes include breast cancer, head and neck,
prostate, testicular, bladder, or colon cancer.
• Surgical disruption of
• Vascular
surgery
lymphatic system
• Risk Factor: Radiation
Radiation therapy to the axillary or groin region around the
lymph node can cause fibrosis and scarring of the tissue and
therefore cause lymphedema to occur
Types of Lymphedema
1- Pitting edema
Short duration edema
Finger indentation of the skin
2- Brawny edema
Tissue feels hard upon palpation
Indicates fibrotic changes
3- Weeping
Fluid leaks, wound healing is impaired
Occurs mostly in the lower extremities
Stages of lymphedema
Stage I
• Considered reversible
• There is lower than 3 cm difference between extremities.
Stage II
• Considered irreversible
• There is 3 to 5 cm difference between extremities.
Stage III
• Tissues are hard and may have cartilage formation developing.
• There is more than 5 cm difference between extremities.
Signs and symptoms
• Painless
swelling of the arms or legs.
• Swelling
• Redness
get worse during the day and better at night.
and Warmth in the extremity.
• A feeling
of tightness and weakness in the affected extremity.
• Bracelets,
• Tends
rings, or shoes may become tight.

• Increased
pigmentation/superficial veins
• Secondary
cellulitis
Measurement Methods
Water displacement – “gold standard”
2. Circumference
3. Perometry
4. Bioelectrical impedance
1.
Water Displacement (Volumetric
measurement)

“Gold standard” for
volume
measurement
(edema size)
1- Water displacement – “gold standard
Circumference

Most commonly used
method to assess limb
volume

Measurements taken at
various points of arm or leg

Time-consuming

Requires considerable
experience
2- Circumference
Examination (Cont)
- Girth measurements of the extremity
(evaluating edema size).
Limb measurements must be done at the set levels
and ideally repeated by the same person. These
measurements are taken in:
1. The upper limb at:
(a) Axilla.
(b) 8 cm proximal to olecranon.
(c) 11 cm distal to olecranon.
(d) Wrist.
(e) Level with web of thumb
Upper limb circumference.

Perometry

Imaging device

Measures limb volume,
circumference, contour,
cross-sectional area

Convenient

Daily living precautions
1- Elevation
*Elevate the involved limb when
using a sequential compression
pump
*Elevate limb when sleeping,
resting, and during sedentary
activities
*Compressive bandages or
garment should be worn during
periods of elevation
1- Position
Elevation of the feet for 10-15 minutes 3-4
times a day
2- Manual Lymphatic Drainage
* Slow, very light, repetitive
stroking and circular massage
movements performed in a
specific sequence, limb elevated
whenever possible.
* Proximal congestion in the trunk,
groin, buttock, or axilla is cleared
first.
* Direction of massage is towards
specific lymph nodes.
* Usually involves distal to proximal
stroking.
3- Compression bandaging and
Garment.
* Compression Garments.
* Once a manageable size has been
achieved from wrapping, a
compression stocking may be worn
to maintain the size and prevent
increased swelling.
* Bandages may be applied to
increase tissue pressure and
counteract the elastic insufficiency
of the connective tissue.

Compression Bandaging

Bandages may be applied to increase tissue
pressure and counteract the elastic
insufficiency of the connective tissue.

Compressive Bandages
4- Exercise
Exercise
* Active range of motion, stretching,
circulatory and low-intensity resistance
exercise is incorporated with manual
drainage techniques.
* Exercises should be performed
with compressive bandages or
garment
* Exercises are performed in a specific
sequence, often with the limb elevated
* Low-intensity
cardiovascular/pulmonary
endurance activities.
* Deep breathing and relaxation.

•Contraindications
•Indications
•Varicose veins
•Thrombosis
•Lymphedema
•Kidney or

diseases
•Chronic
venous
insufficiency
•Cancers
Vasotrain 447
6- Electro modalities
• Ultrasound
: Pulsed , 0.1-0.3 W/cm2; for 5-8 minutes
• Pulsed ultrasound at a lower intensity will produce
mechanical and non thermal effects that will soften
fibrotic tissues.
• Ultrasound may be used for its fibrinolitic effects on
lymphostatic fibrosis.
7- Good skin care
• Keep
the skin clean and dry
• Apply moisturizer daily
• Protect skin with sunscreen and insect repellant
• Use care with razors
• Wear gloves during activities
• Avoid extreme temperatures
Daily living precautions
• No blood draws, finger pricks for blood sugar testing, IVs,
blood pressures, or injections should be taken on the affected
extremity.
• Anything that may cause pressure needs to be avoided
including:
*Blood pressure cuffs
*Tourniquets
*Tight clothes (waist bands, bra straps, socks)
• This constricts collateral circulation
Precautions
• Heat
may cause vasodilatation, which causes more fluid to move
from the blood vessels into the tissues. Avoid hot showers and
saunas.
• Cold may cause rebound swelling or chapped skin
• Air travel more than 2 hours increases the risk of swelling because
of continuous reduction of cabin pressure.
• It is recommended to wear a compression stocking while flying.
• Avoid carrying a purse, briefcase, or other heavy item with the
affected extremity.
• If the lower extremity is affected, avoid standing or sitting for long
periods of time and do not cross legs.
