Traumatic arteriovenous fistula: a 25-year delay in presentation

A 64-year-old lady presented with a 6-month history of worsening unilateral leg swelling, with an audible bruit of the popliteal artery. Arterial duplex ultrasound confirmed the presence of an arteriovenous fistula (AVF) between the posterior tibial artery and vein. Upon thorough history, it was discovered that the patient had sustained a stab wound to this region some 25 years prior. The fistula was successfully managed endovascularly by means of a covered stent. This case highlights an unusual delayed presentation of an AVF and demonstrates the effectiveness of endovascular treatment of this condition.
