Popliteal arteriovenous fistula following total knee arthroplasty

Postoperative popliteal arteriovenous fistula is a very rare complication. We report a unique asymptomatic fistula in a 77-year-old male patient, seven months after total knee replacement. The diagnosis was suspected by a clinical palpable thrill and confirmed with a typical doppler ultrasound signaling. This vascular malformation was successfully treated by surgical resection of the fistula. Referring to the literature, considering the management of popliteal aneurysms, we suggest to prefer an open procedure in patients who are in good general condition
