Abstract
The authors present an extremely rare case of a pseudoaneurysm of the ulnar artery as a complication of a two-portal endoscopic carpal tunnel
release (ECTR). A 70-year-old man with chronic renal failure and on maintenance hemodialysis with a left arteriovenous fistula presented with
paresthesia of his right hand. A clinical diagnosis of right carpal tunnel syndrome was confirmed by ultrasonography and an electrophysiologic
study. He underwent two-portal ECTR, and the paresthesia was much improved. However, he presented to us one month after operation with
severe pain, a tender mass distal to the right wrist crease and more aggravation of the paresthesia in the ulnar nerve distribution. Doppler
ultrasound was performed and revealed a hypoechoic lesion 20 mm in diameter in the right palm, with arterial Doppler flow inside connected to
the palmar segment of the ulnar artery. An ulnar artery pseudoaneurysm was diagnosed and treated by ultrasound-guided percutaneous
thrombin injection. Transverse color Doppler ultrasound image showed complete thrombosis of the pseudoaneurysm and flow cessation after a
total injection of 500 units of thrombin. The symptoms were also improved.
