Week 4 Part 1 Flashcards
Carotid body tumors are also known as
paragangliomas
Where are carotid body tumors located?
in the adventitia of the carotid bifurcation– b/w ICA and ECA
What is the most common presentation of a carotid body tumor?
palpable neck mass with headache
neck pain is second most common
What is the standard treatment for carotid body tumors?
resection
if untreated, stenosis, occlusion or rupture could occur
On 2-D and CD, ICA and ECA appear
splayed
What demonstrates vascular nature of mass prior to surgery
arteriography
Carotid body tumors can be mistaken for what?
node
Do CBT have high or low vascularity?
lots of flow but low speeds
Who does FMD typically affect?
women ages 25-50
not genetic but familial
What’s the most common site for FMD? What’s the second most common?
renal arteries, ICA
FMD presents with
system hypertension caused by renal artery stenosis
When carotids are involved with FMD, what does this present as
transient cerebral ischemia (stroke can occur)
What does FMD appear as on angiography?
string of beads
Which layer of the vessel is most often involved with FMD?
tunica media
What’s the typical flow in a vessel with FMD?
long stenosis but no atherosclerosis
flow disturbances
elevated velocities- 200cm/s
What are some vascular diseases of the fem artery? (3)
PSA
AVF
Penetrating arterial trauma
What is the most common entry route in the fem artery for a PSA?
groin area
PSA’s arise from the deep portion of the artery at the site of the puncture. True or false
false– superficial aspect
