Peripheral Arterial Disease - Acute

Etiology

  • Emboli from a fib w/o warfarin, or ventricular thrombus if severe lv dysfxn
  • Recent catheterization where plaque disrupted from aorta and lodges distally
  • Emboli can also originate from proximal aneurysm
  • Thrombosis in situ can occur in a distal artery

Risk Factors

  • Hypertension, hyperlipidemia, diabetes, atrial fibrillation, smoking, known vascular disease, low EF

Symptoms

  • Acute onset of severe leg pain
  • Symptoms typically present at rest

Physical Exam Findings

  • Affected area of leg can be pale appearing
  • Diminished pulses (e.g. dorsalis pedis, posterior tibial arteries) distal to occlusion
  • Affected area of leg feels cool
  • Blue/hypo-perfused toes if distal emboli (e.g. following catheterization)
