摘要：A 25-year-old female presented with a 3-month history of venous ectasia and vascular murmur in the left arm. Her symptoms had begun after she sustained blunt trauma to the forearm. Computed tomographic angiography with three-dimensional reconstruction demonstrated a tortuous arteriovenous fistula (Panel A, long arrow) in the vicinity of the ulnar artery and early contrast filling of the veins (Panel A, short arrows) during the arterial phase. Digital subtraction angiography revealed a high-flow arteriovenous fistula (Panel B, long arrow) with ulnar artery origin. Through various looping and vascular angulations, it finally drained into the basilic vein (Panel B, arrowhead) atid cephalic vein (Panel B, short arrow). Surgical arteriovenous fistula resection (Panel C, arrow; Panel D) and repair of the ulnar artery were performed. Histopathology of the surgical specimen confirmed the diagnosis of arteriovenous fistula. The patient\'s postoperative course was uneventful, and she remained asymptomatic during follow-up.
