Popliteal Traumatic Arteriovenous Fistula after Blunt Trauma: A Case Report

Due to the rarity of the popliteal intravenous artery following posterior knee dislocation, this study will explain a rare case.

 This case report describes a 46-year-old man with blunt trauma, posterior knee fracture and cruciate ligament arthroscopy and ligament repair. In the postoperative follow-up, the patient developed pain and swelling. On examination, there was a thrill in poplité and lower extremity edema. Doppler ultrasonography and angiography confirmed the presence of arteriovenous fistula in the popliteal area. The patient underwent surgery and discharged without any complication.

Complications of posterior knee dislocation are usually thrombosis and ischemia of the limb. As venous arterial fistula following blunt trauma to the knee is rare, lack of diagnosis and consequently delayed treatment can cause irreversible complications; therefore, surgeons should always consider the possibility of these complications.
