what ABI is indicative of peripheral arterial disease
<.9
what significantly increases risk of developing PAD
tobacco use
What timeframe is dangerous for limb ischemia 2/2 acute arterial occlusion? what can happen
4-6 hrs
can cause irreversible changes in peripheral nerves and skeletal muscle tissue
what are the most frequently diseased arteries for limb ischemia
what are the MC sites of arterial embolism
what are the six P’s
pain
pallor
paresthesia
poikilothermia
paralysis
pulselessness
what is the earliest symptom of acute arterial occlusion? how can this sympotm worsen?
pain!!!
worsens with elevation of the limb
what is claudication and how common is it in PVD
what is the MCC of acute arterial occlusions?
thomboembolic disease
what history would strongly suggest that an embolus is present and is the cause of limb ischemia
a history of an abrupt ischemic event in a pt with afib or recent MI
what are the diagnostic modalities used to evaluate limb ischemia/acute arterial occlusion?
what is the treatment for acute arterial occlusion
If a patient has PAD with no comorbidities and iscemia with no critical threat to the limb (ABI>.4) what is the treatment
DC on ASA 81mg with loading dose of 325mg prior to DC
idk if we need this but might be good.
what is the classic presentation of a LE DVT
calf or leg pain
redness
swelling
tenderness
warmth
present in fewer than 50% of patients
In what setting do UE DVTs often occur
indwelling catheters! presents the same as LE
what two PE findings are predictive but not specific or sensitive for DVT
what is phlegmasia cerulea dolens and what is its presentation
what is phlegmasia alba dolens
idk these had their own paragraph so maybe
what are the diagnostics for DVT
wells score
If wells score is 0 then what is the diagnostic workup?
if it is 1 or more what is the diagnostic workup?
0 = ddimer
1 = US
what can elevate D-dimer
