Abstract
Traumatic arteriovenous fistulas (AVFs) are uncommon and can be associated with significant morbidity. Given their complex anatomy, diagnosis and treatment can be challenging. We present the successful management of a patient with a 7-year history of a lower extremity traumatic AVF, which led to chronic venous insufficiency and nonhealing venous ulcers. This case highlights how precise anatomic definition enabled targeted endovascular repair of a complex AVF.
