Iatrogenic Interval Gangrene of the Thigh

Interval gangrene of the thigh is an extremely rare complication in vascular surgery. Most cases have reported interval gangrene of the calf as a consequence of a distal bypass procedure, with little documentation of interval thigh gangrene occurring after endovascular intervention. The present case suggests that in the process of placing multiple-level covered and bare metal stents in the iliac, superficial femoral, and popliteal arteries, interval gangrene of the thigh must be considered as a potential, albeit rare, complication. Preservation of pelvic and profunda femoris flow to the thigh is imperative to prevent the development of interval tissue loss. This case demonstrates the importance of maintaining profunda femoris circulation, especially in patients with significant vascular comorbidities.
