Post-traumatic concomitant popliteal artery pseudoaneurysm and arteriovenous fistula

Popliteal injuries are well known to be serious with a high rate of mortality due to damage caused to popliteal vessels. Pseudoaneurysm formation and arteriovenous fistulas are well-known complications of arterial injury, but are rarely concomitant. Diagnosis is usually done by computed tomography (CT) angiography. Treatment strategies consist of surgery or endovascular management. We report the surgical treatment of two cases of popliteal arteriovenous fistula associated with pseudoaneurysm complicating stab wounds.
