Traumatic popliteal arteriovenous fistula. Diagnostic methods and surgical management

The popliteal vessels rank second only to the external iliac system as the most frequent site of acquired arteriovenous communication. Direct trauma to the popliteal space is by far the most common cause, and surgical intervention is usually required to manage the defect. We present a recent illustrative case following meniscectomy. To our knowledge, the occurrence of an arteriovenous fistula complicating knee surgery has not been reported previously. This case outlines the potential value of B-mode ultrasound in diagnosis and the use of intraoperative angiography in assessing the adequacy of primary vascular reconstruction. Earlier experience of this vascular abnormality--six additional cases since 1941--is reviewed.
