anterior vertical (parallel)

incision is made from a point near the sternoclavicular articulation and is directed superiorly along the sternocleidomastoid muscle

posterior vertical (parallel)

incision is made posterior to the sternocleidomastoid muscle, 2 inches below the lobe of the ear, and is directed downward toward the base of the neck

- common carotid

- femoral (or external iliac if raised by the inguinal filament)

- axillary (or brachial)

the three most common arteries raised for arterial injection:

smaller

__________ arteries are usually reserved for secondary injection sights

internal jugular vein

what vein is the companion to the common carotid artery?

femoral vein

what vein is the companion to the femoral artery?

axillary vein

what vein is companion to the axillary artery?

basilic vein

what vein is companion to the basilic artery?

internal jugular vein

which vein is most commonly used for blood drainage? (hint: it's close proximity to the right atrium of the heart makes it an ideal pairing with any artery selected)

nerves

solid structures lacking the lumen present in both arteries and veins; they have a silvery white appearance with visible striations; if incised, the edges fray similar to the ends of a cut rope

veins

thin walled vessels that contain a lumen; they have a blush appearance when filled with blood; opaque when not blood-filed; have internal valves to prevent backflow of circulating blood

lumen

the opening or inside space of the vessel or other tubular structure

vein

upon mistakenly injecting a _______, the telltale sign is that fluid will not distribute and instead flow back out from the vessel; it will collapse on itself when cut

arteries

thick walled vessels that contain a lumen; the lumen stands open and pronounced when cut; do not have valves which makes them suitable for injection in either direction of the vessel

vasa vasorum (vv)

"vessels on vessels"; tiny blood vessels that supply the large vessel walls with nutrients

case analysis

how do we determine which vessel to raise for injection?

injection; drainage

arteries are used for ______________ while veins are used for _____________

ligatures; fixation forceps

the cannula is placed into the artery and then secured with either ____________ or arterial _____________ _____________

heart; right atrium

desired drainage instruments should be inserted into the vein toward the __________; specifically the _________ ________ if possible

drain tube or angular fixation forceps

these two instruments may be used for drainage:

the right common carotid artery and the right jugular vein

the vessels most commonly used for arterial embalming are:

ANV

the acronym ______ is helpful to describe the relationship of the common carotid artery, vagus nerve, and internal jugular vein

opposite

when accessing the common carotid artery for arterial embalming, turn the head of the body in the direction _____________ that of the vessels bring raised

ligate

to tie off

facial artery

one of the eight branches of the external carotid artery; usually reserved for injection of the facial tissues when the common carotid artery is either damaged or unavailable

axillary artery

in the early years of embalming the __________ ________ was the preferred site to inject the entire body; now it's used principally as a secondary point of injection

right internal jugular vein

this vein is often used for blood drainage as the axillary vein is relatively small and may not evacuate clotted materials

90

when accessing the axillary artery for arterial embalming, the arm must be raised slightly less than ____ degrees from the trunk

brachial artery

continuation of the axillary artery and used principally as a secondary point of injection to reach the forearm and hand

radial artery

originates at the bifurcation of the brachial artery and supplies solution to the lateral side of the hand (thumb)

ulnar artery

originates at the bifurcation of the brachial artery and supplies solution to the medial side of the hand (little finger)

femoral artery

the second more frequently used vessel for arterial embalming; continuation of the external iliac artery and located superficial and lateral to the femoral vein

VAN

the acronym ______ is helpful to describe the relationship of the femoral vein, femoral artery, and femoral nerve

popliteal artery

continuation of the femoral artery and can be used as a secondary injection site when solution has not distributed below the knee

popliteal

the location and size of the _____________ vein makes it unsuitable as a drainage site

anterior and posterior tibial arteries

supply arterial solution directly to the portion of the leg below the knee into the foot

aorta

the largest artery in the body, traveling the length of the torso along the midline; may be selected for infant embalming when commonly used arteries are too small for injection

abdominal and thoracic aorta

either of these can be used for injection following partial autopsy or organ donation

external iliac artery

passes beneath the inguinal ligament and lies on the lateral side of the external iliac vein; supplies solution to the lower extremity and anterior abdominal wall

internal iliac artery

supplies embalming solution to the external genitalia, gluteal muscles and the peroneal regions; following a complete trunk autopsy, it may be accessible from within the pelvic cavity

inferior vena cava

the largest vein in the body; located to the right of the aorta at the posterior abdominal wall; primarily used for blood drainage in cases of partial autopsy or organ donation

right atrium of the heart

the center for venous drainage in the dead human body; routinely (during embalming of a nonautopsied body) a drainage device is inserted into the right jugular vein and guided into this

direct heart drainage

historic method first practiced when embalming was done at the residence of the deceased; today it is recommended for infectious cases to eliminate contact with blood and bodily fluids
