Abstract
Traumatic arteriovenous fistula (AVF) is not uncommon disorder, however its late discovery and presentation as high-output heart failure are rare. We report a case of traumatic superficial femoral AVF diagnosed approximately 40 years after initial injury. A 63-year-old man complaining of dyspnea was referred to our hospital. He had a history of a stub injury to the left thigh 40 years ago. Computed tomography (CT) and angiography revealed left superficial femoral AVF. After establishing the diagnosis of high-output heart failure due to the traumatic AVF, we performed surgical repair. After surgery, the patient’s symptoms improved significantly, but the left superficial femoral vein was thrombosed.
