Acute ischemia after revision hallux valgus surgery leading to amputation.

Acute arterial insufficiency after revision hallux valgus surgery is a rare complication. The identification of surgical candidates who are at risk of vascular complications is of utmost importance. The patient-reported symptoms and physical findings combined with noninvasive vascular studies are generally reliable to assess the vascular status but can fail to identify patients with atypical disease patterns. We present the case of a patient with normal pulses who underwent revision hallux valgus surgery, leading to gangrene of the hallux that required transmetatarsal amputation. We reviewed the vascular evaluation methods and causes of acute ischemia after surgery, including vasculitis.
