Exam #3, things you keep missing Flashcards
Superior Cerebellar Artery, where is it
visualize, revisit diagram
hemodynamically significant lesions do what
restrict flow
thromboembolic plaque does what
sends small clots into the distal circulation
not the residual lumen but the
true lumen
common site of stenosis
carotid bifurcation
DVT of the lower extremity would have us concerned about venous circulation. why?
pulmonary embolism (possibility of)
soft, fibrous plaque is darker or lighter than other types of plaque
darker!
tunica externa or tunic media, which is thicker?
media
remember function dictates form
the tunica media and the tunica external BOTH have smooth muscle fibers…. true or false?
TRUE!
Celiac artery (trunk) off the abdominal aorta branches into what arteries. These arteries feed what?
- branches into left gastric, splenic, and common hepatic arteries.
- feeds the stomach, liver, pancreas, duodenum, and spleen.
superior mesenteric artery feeds what
small intestine, cecum, ascending colon, part of the transverse colon
left and right renal arteries supply blood to what
kidneys, suprarenal glands, ureters
inferior mesenteric artery supplies blood to
left half of transverse colon, the descending, iliac, and sigmoid colon and part of the rectum. Comes off 3-4 cm above the aortic bifurcation
at what junction does the common iliac artery divide in the internal and external iliac arteries
lumbosacral junction
when artery does the external iliac artery become?
common femoral artery
subclavian artery becomes what artery and where
becomes axillary artery at outer border of 1st rib
axillary artery becomes what artery
brachial artery
brachial artery bifurcates into what arteries
radial and ulnar artery
volar arch aka
superficial palmar arch
ICA branches and blood supply
gives off first branch, ophthalmic artery after it passes into the skull.
then gives off anterior choroidal artery, posterior communicating artery, finally dividing into middle cerebral artery and anterior cerebral artery
supplies blood to anterior brain, eyes, forehead, and nose
ECA branches and blood supply
gives off 8 branches (branches BEFORE enters skull, as opposed to ICA).
supplies blood to neck, face, scalp.
comes off subclavian arteries and unite to form basilar artery after they enter skull through foramen magnum
because of effects of venous thrombosis, increased venous pressure from gravity, increased intraabdominal pressure, and venous obstruction in the lower extremities, WHAT is more prone to disease
Valves in the lower extremities
the common carotid, internal carotid, and external carotid all have what type of waveforms?
monophonic waveforms
In a lower extremity arterial exam, BOTH legs are evaluated. True or False?
TRUE, both arterial systems are examined
main method used for evaluation of bypass grants or pseudo aneurysms of LEA systems
Duplex evaluation (direct evaluation)
would include: actual images (transverse and longitudinal) of blood vessel while using color flow and PW Doppler
this type of testing uses blood pressure cuff measurements and Doppler waveforms only NO ACTUAL IMAGES
indirect arterial evaluation
This type of testing can evaluate collateral circulation
INDIRECT arterial evaluation (even though NO ACTUAL IMAGES!*)
lower extremity venous evaluation concententrates on SUPERFICIAL or DEEP venous system
DEEP VENOUS SYSTEM to detect DEEP VEIN THROMBOSIS (DVT)
Veins are compressed to prove the absence of clots. TRUE or FALSE
TRUE!
