Abstract
Blunt trauma to the upper extremity sometimes causes a brachial artery pseudoaneurysm. However, venous injuries from blunt trauma may also result in a pseudoaneurysm in patients with an arteriovenous(AV) fistula for hemodialysis. A 62-year-old man presented because of aggravating swelling and resting pain in his upper extremity 3 weeks after a traffic accident. Computed tomographic angiography demonstrated a pseudoaneurysm of the cephalic vein close to the anastomosis of the brachiocephalic AV fistula. An aneurysmectomy was successfully performed. Attention has to be given to the risk of venous pseudoaneurysm caused by venous injuries from blunt trauma in patients with an AV fistula.
