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
Adson’s manuever:
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
chronic- wt loss, post prand discomfort
acute abd pain out of proportion to exam
SLE
antiphospholipid antibody
recurrent thromobosis
CVA
tpa unless bp >180
< time limit
cva med rx
2b3a
2b3a harmful bleeding
asa class 1 indication
asa/dipyridimole
vasculitis types
large: temporal arteritis- giant cell
takyasu
medium: polyarter nodosa, kawasaki
small: bergers’ (smoking, low sed rate)
Takyasu s disease
Pulse less disease
Aortic arch syndrome
Paradoxical splitting of second heart sound
Severe AS
Leopard syndrome
Auto dominant:
Lentingines, ecg abnl, ocular hypertelorism, pul stenosis, abnl genitalia, retard growth, deafness- sensorialneural
No mitral stenosis
Ortner’s syndrome
Hoarseness in mitral stenosis due to recurrent laryngeal nerve by increased left atrium
Lutembacher’s syndrome
Rheumatic MS with asd
Wall stress
Laplace law
Wall stress is directly related to pressure and radius of cavity, inversely related to 2x wall thickness
Therefore, lvh reduces wall stress
