Endovascular management of a traumatic lower extremity arteriovenous fistula following a machete injury

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.
