CHAPTER 9
EMBALMING VESSEL SITES AND SELECTIONS
TERMINOLOGY
 One-Point Injection- One artery and one vein is used at the
same site. Example: injection from the femoral
artery and drainage from the femoral vein.
 Split Injection- Only one artery and vein are used, but at
different locations. Example: injection from the
common carotid artery and drainage from the femoral
vein.
TERMINOLOGY
 Restricted Cervical Injection- The right jugular vein is used
for drainage while injection is in the left and right
carotid towards the head and the right carotid
towards the trunk. This will be discussed in much
more detail later.
TERMINOLOGY
 Multi-point Injection- Injection from two or more arteries.
Example: injecting the carotid and the femoral to
achieve the desired results.
 Types are:
• Restricted cervical injection
• Six-point injection
• sectional vascular injection
TERMINOLOGY
 Sectional Vascular Embalming- can be used for an
autopsied or un-autopsied case. It is used to
separately inject a particular body region. The body
regions are there vessels are:
TERMINOLOGY
 Face and Head: Common carotid artery
 Upper Extremity: Subclavian, axillary, brachial artery
 Hand: radial or ulnar artery
 Lower Extremity: Common iliac, external iliac, femoral
artery
 Body Trunk: in the un-autopsied body, injection of any
major artery toward the trunk region.
TERMINOLOGY
 Six-Point Injection: Six arteries are raised to inject the head
and limbs.
 They are:
• right and left common carotid arteries
• right and left axillary (or brachial)
• right and left femoral (or external iliac)
VESSEL SELECTION
 In the unautopsied body the arteries most frequently used
for embalming are the:
• common carotid
• femoral, and
• axillary arteries.
 Most cases start out as a one-point injection but require
additional vessels to be raised to achieve the desired
results.
VESSEL SELECTION
 How to determine if a one-point injection is enough:
•
•
•
•
•
•
inject
observe and evaluate
if needed perform sectional embalming
inject again
observe and evaluate again
if needed perform some form of supplemental embalming
GENERAL CONSIDERATIONS
OF VESSEL SELECTION
 The right side of the body is used for several reasons
including:
• most embalmers are right-handed making it easier to
work on the right side of the body,
• instruments are inserted easier and are more effective
in the right internal jugular vein. (think back to
anatomy class-more direct path.)
NERVE CHARACTERISTICS
 Nerves are:
•
•
•
•
•
•
solid structures
with a silvery white sheen
that show striations along their surface
and do not have a lumen ( an opening) when cut.
They do not have blood in them
and the vasa vasorum are not visible.
VEIN CHARACTERISTICS
 Veins are :
•
•
•
•
•
•
thinner than arteries
and contain valves
that when cut they have a lumen
and collapse to create a funnel effect.
They are bluish when filled with blood
and the vasa vasorum are not visible.
ARTERY CHARACTERISTICS
 Arteries have:
•
•
•
•
thick walls,
are creamy white in appearance,
the vasa vasorum can be seen.
The lumen of an artery is very pronounced when cut
as the walls do not collapse.
• They are elastic and can be easily stretched .
SELECTING AN ARTERY
 As these questions:
• How superficial or deep is the artery? In an obese
person the femoral artery could be very deep and hard
to secure or in a person who has lost significant weight
during the dying process they femoral could be
superficial making it an ideal vessel to select.
• What structures surround the artery?
SELECTING AN ARTERY
 Criteria that should be considered when contemplating an
injection site. (mutilation?)
 How close to the aorta is the artery? Remember the closer
the vessel to the aorta the better the results.
 What is the diametric size of the artery? Is it so small you
don’t have a canula to fit in it? Or is it large enough
to be able to use a decent amount of pressure?
SELECTING AN ARTERY
 Can the body be positioned properly if this artery is used?
 Unless you’re trying to get instant fixation of the tissue any
artery can be used and the body positioned
immediately after injection, such as the axillary.
SELECTING AN ARTERY
 Will incisions for the artery be on an exposed body area?
 This is why I have never the seen the facial artery used. Also,
funeral directors used to ask families to bring in a dress
with a high neck line for the women so the incision
wouldn’t show. Today, a good embalmer doesn’t
need to “hide” behind a high neck dress.
SELECTING AN ARTERY
 Can drainage be taken from the vein which accompanies the
artery?
 An example of where drainage potentially wouldn’t be taken
would be the radial and ulnar. The veins are so small that it
wouldn’t be worth cutting and would only give you another
incision to have to seal.
SELECTION OF THE
ARTERY
Other factors to include when selecting an artery
AGE OF THE DECEASED
 Infants- the carotid artery is the largest and should be selected for
that reason.
 Elderly- many times the femoral artery is sclerotic so it is not
chosen first.
GENDER
 What the family chooses for the deceased to wear is a very small
factor in choosing a vessel. You should be able to accommodate a
family’s choice as well as provide the most complete embalming
necessary.
WEIGHT
 In obese bodies the femoral artery is very deep and may not be
able to be used.
 In very thin bodies the SCM can be pronounced and care should
be taken when using the carotid the protect the SCM.
FAT DISTRIBUTION
 People carry their weight in different areas of their bodies. Be
aware that they may require more than 1 injection site to properly
embalm the entire body.
DISFIGURATIONS PRESENT
 Examples are:
• arthritic conditions
• tumors
• scar tissue
 Try to avoid these areas as the vessels that lie beneath them may
have some damage to them or simply may be hard to raise.
DISEASE CONDITIONS
 Examples include:
 Gangrene- Don’t use the vessels where there are signs of
gangrene, it is probably a sign that there is poor blood supply.
 Burned Tissue- Avoid burned tissue if possible as leakage will be a
problem when suturing.
EDEMA, LOCALIZED OR
GENERAL
 Generalized edema is called anasarca.
 When edema is generalized a restricted cervical injection should be
used to avoid having to raise several arteries on the body which could
lead to leakage problems.
 Large quantities of fluid should be injected for generalized edema.
INTERRUPTION OF THE
VASCULAR SYSTEM
 Mutilation or Trauma: car accidents or accidental death can result
in severed arteries. These bodies require more than one point of
injection and the the several arteries will have to be clamped during
the injection.
INTERRUPTION OF THE
VASCULAR SYSTEM
 Ulceration's: Ruptured blood vessels can be the result of
ulceration's. The embalmer may notice that there is a lot of arterial
fluid coming out with the blood. If this occurs the embalmer may
need to sectionally treat the body.
INTERRUPTION OF THE
VASCULAR SYSTEM
 Autospies- Depending on the type of autopsy; partial or complete,
the embalmer may have to choose which vessels to use.
TRAUMA
 Trauma may be present from:
• mutilation
• accident
• surgery
MEDICO-LEGAL
REQUIREMENTS
 This can include:
•
•
•
•
preparation for medical schools
international shipping
under military contracts
coroner or medical examiner
 Each of these situations may have written protocol the embalmer
must follow.
CAUSE OF DEATH
 Example- depending on how a person died you may or may not
have all of the arteries available to you for selection.
MANNER OF DEATH
 Example- a bullet wound could sever a major artery and make it
unavailable for selection.
 Example- a natural death of a person could mean that you have all
the arteries available to you for selection.
CLOTTING
 If an embalmer feels that clots may be present they should use the
carotid artery as a starting point for injection and then select
subsequent vessels if needed.
FACIAL TISSUE
DISTENSION
 Always use a restricted cervical injection if facial tissue distension
is present or if it becomes an issue.
FACIAL DISCOLORATION
 Many times when a person dies from a heart attack the jugular
veins are distended, in order to help rid this pressure use the jugular
vein for drainage will help clear this tissue.
VOLUME AND
STRENGTH ARTERIAL
SOLUTION
 If the embalmer needs to use a large volume of fluid with a strong
solution then a restricted cervical injection should be used to avoid
over injection of the fluid to the facial tissue.
SIZE OF THE ARTERY
 Use the largest artery available because it will be more elastic and
will allow for the use of higher pressure and faster rates of flow
which will help the solution distribute more evenly.
ELEVATION AND
LIGATION OF VESSELS
THE 10 STEPS TO
“RAISE” A VESSEL
 1. Select the instruments and prepare the thread you will be using. ( You will
probably have a tray will all the instruments you need for the embalming.)
 2. Locate the vessel by the linear guide.
 3. Make the incision where the vessel in nearest the skin surface. (The closer the
vessel is to the surface the easier it will be to work with.)
THE 10 STEPS TO
“RAISE” A VESSEL
 4. Make the incision.
 5. Dissect the muscle to get to the vessel, don’t cut it..
 6. When both the artery and corresponding vein are to be used always raise the
superficial vessel first, this will make locating the deeper lying structure easier.
• Always insert the instrument into the deeper lying vessel first.
THE 10 STEPS TO
“RAISE” A VESSEL
 7. Always use an arterial tube slightly smaller than the opening of
the artery that will make the insertion easier and will protect the vessel
from breakage.
 8. If clotted material is present, try and remove it before inserting
the arterial tube.
 9. Search for the softest portion of the artery to insert the arterial
tube.
THE 10 STEPS TO
“RAISE” A VESSEL
 10. If the artery is accidently broken the ends must be found and
closed before a new arterial tube can be inserted.
INSTRUMENTS
 Scalpel- Used for making the incision.
 Double-point scissors- Used for making the incision and cutting
the ligature.
 Aneurysm needle- Used for dissecting fat and fascia; elevating
vessels at surface.
 Bone Separator- Used for elevating vessels at the skin surface.
INSTRUMENTS
 Arterial Tubes- Used for insertion into the artery for injection of
the fluid.
 Drainage Tube- Used for insertion into the vein for drainage
control.
 Angular Spring Forceps- Used for insertion into the vein for
drainage control.
 Straight Spring Forceps- Used for passing ligatures around the
vessels.
INSTRUMENTS
 Grooved Director- Used for assisting in the expansion of the vein
for insertion of the drainage device.
LIGATURE
 Ligature is a fancy word for string.
 Usually the string that an embalmer uses is heavy and thick and
made of linen or cotton.
 Many embalmers use dental floss to sew cranial autopsy’s and the
right carotid incision when a hidden stitch is used.
 The ligature should be 8 to 12 in. in length.
COMMON CAROTID
ARTERY
REGIONS SUPPLIED
 The head and face if in injection is superior.
 The entire body if the injection is inferior.
PRO’S- IT IS:
large,
easily raised to the skin surface,
elastic,
rarely found to be sclerotic,
the artery that supplies fluid directly to the
head,
CON’S
 The head may be over injected.
 If leakage occurs, it may be seen.
 Some types of instrument may mark the side of the face or jaw
line if used improperly.
 The incision may be visible with some types of clothing.
INCISION
 The most commonly used form of incision is the Anterior Lateral
(supraclavicular): The incision is made on the clavicle from a point
near the sternoclavicular articulation and is directed laterally. This is
pictured on page 165 of your textbook. There is no need to learn
the other types of incisions for the common carotid artery.
PROTOCOL FOR RAISING
THE CAROTID
 1. Stand at the head of the embalming table.
 2. Turn the head to the left to raise the right common carotid.
 3. Remove the head block, this will give you more area to work
with and will avoid having to work around the head block. (NOTE:
this is my step 3, not the books suggestion, I think this works better.)
PROTOCOL FOR RAISING
THE CAROTID
 4. Make the incision.
 5. Find the SCM muscle at the clavicle.
 6. Raise the internal jugular vein and tie it off.
 7. Go MEDIAL AND DEEP to find the carotid and bring it to
the surface, bring two strings around it, cut it, and insert the arterial
tube, secure the tube with string.
PROTOCOL FOR RAISING
THE CAROTID
 Open the vein and insert a drain instrument.
INTERNAL JUGULAR
VEIN
PRO’S, IT IS:
 large,
 the vessel that provides direct drainage from the face and head,
 accompanied by the common carotid artery,
 close to the superior vena cava allowing easy removal of blood
clots.
CON’S
 Leakage may be visible.
 Drainage instruments if used improperly may mark the face.
 The incision may be visible with some clothing.
 These are the same con’s at the common carotid artery as the
incision is made in the same place.
THE RESTRICTED
CERVICAL INJECTION
Procedure:
• Raise the right common carotid (rcc) artery and the right internal
jugular vein.

ANTERIOR AND
POSTERIOR
TIBIAL ARTERIES
CHARACTERISTICS
 Supplies:
• foot

• they are deep making them hard to find.
EXTERNAL AND
INTERNAL ILIAC
ARTERY
CHARACTERISTICS
 In the autopsied body the external iliac artery supplies solution to
the lower extremity and the anterior abdominal wall.
 In the autopsied body the internal iliac artery supplies solution to
the gluteal and the peroneal regions.
 I am skipping :
• Abdominal Aorta and Thoracic Aorta
• Inferior Vena Cava
• Right Atrium of the Heart
 It is extremely unlikely you will ever need to use these when
embalming and if you do ask someone to help you that knows what
they are doing.
MAKING THE INCISION
 The most common incision is the transverse incision.
 As soon as you see the lumen STOP CUTTING!
