Q

What physical exam test can distinguish PAD from cellulitis?

A

Buerger test

  • red discoloration that goes away with leg elevation is consistent with PAD
  • this does not happen with cellultis!

18
Q

For patients with diabetes or ESRD who may have falsely elevated ABIs d/t calcifications what test is more accurate for PAD?

A

toe pressures or TBI

19
Q

What are the 3 indications for measuring ABI in asymptomatic patients?

  • age 50-69 and history of smoking or diabetes
20
Q

What do the 3 Rutherford Grades correlate with?

A

improve walking distance during exercise

27
What are the 4 signs and symptoms consistent with subclavian steal syndrome?
- unequal UE BP - arm claudication - arm or hand ischemia - neurologic symptoms (e.g. dizziness, visual changes, syncope)
28
What are the 2 reasons for intervention for subclavian steal syndrome?
- severe symptoms | - maintain LIMA bypass

The main risk factor associated with arterial occlusion is what cardiac arrhythmia?
atrial fibrillation
33
What are the 6 P's of limb ischemia d/t arterial occlusion?
- pulselessness - pain - poikilothermia - pallor - paresthesia - paralysis

In acute limb ischemia there is irreversible damage after ___ hours.
6 hours
35
What is the treatment for arterial occlusion?
emergent/urgent revascularization via thrombectomy OR embolectomy
