Arteriovenous Fistula after Anatomic All-Inside Anterior Cruciate Ligament Reconstruction

Abstract

We present the first case of an arteriovenous fistula after an all-inside anterior cruciate ligament (ACL) reconstruction. A seventeen-year-old boy had an uneventful ACL reconstruction. Four weeks after surgery, the patient was seen with a pulsating swelling at the lateral distal upper leg. Vascular consultation led to the diagnosis of pseudoaneurysm and arteriovenous fistula of the lateral superior genicular artery. Most likely, fistula is caused by the stab incision for preparation of the femoral tunnel, and no anatomical cause was found. The clinical presentation, previous cases of arteriovenous fistula after arthroscopic ACL reconstruction, possible causes, and management are discussed.
