Abstract
A 39-year-old man presented with the acute onset of a cold, painful, and numb left leg. Physical examination in the emergency room demonstrated a palpable left femoral pulse and absent left popliteal, dorsalis pedis, and posterior tibial artery pulses. The left foot and lower leg were pale and cool to touch, and the patient exhibited diminished sensation over the anterior foot and decreased mobility at the ankle joint. Vascular examination of the right lower extremity was entirely normal. Past medical history was remarkable only for recreational drug use consisting mainly of cocaine.
