Vascular Disease Flashcards
Aortic Dimension normals:
root 3.0 cm
descending 2.5cm
infrarenal 2.0 cm
Aortic Aneurysm dimensions/locations:
AAA >3.0
>50% size of normal proximal dimension
Thoracic > 4.0 or guideline >4.5 cm
Thoracic aneurysm
> 5 cm grow @ 0.1cm/yr
5 yr survival 60%
Thoracic Aortic Aneurysm
surgery >5.5 cm
descending surg 6.5-7.0cm
increased morbitity- paralysis
AAA characterisitics
male
>5 cm 25% rupture 5 yrs
class 1 indication for repair 5.5 cm
AAA screening known AAA
if 4-5.4 cm every 6-12 mth
< 4.0 every 2-3 yr
AAA screen general population
do not screen women (by guideline recs class 3) males 65-75 y/o who smoked
Aortic dissection med rx:
b blocker
watch for toxicity if nipride used prolonged
medical therapy for claudication
pletal- cilostazol
phosphodiasterase inhibitor- not for use in chf pts
50 bid titrate to 100 bid- prolongs ambulation
ABI calculation
highest arm pressure/ highest pressure in dp or pt
1.3 similar prognosis to abnl abi

Thoracic outlet obstruction:
1st rib removal
CVA types:
97% ischemic
20% carotid
30% cardiac
renovascular hypertension
25% of malig htn due to rv htn
mesenteric ischemia:
types:
acute/chronic
