Pseudoaneurysm of a high origin radial artery treated by ultrasound-guided compression.

A high origin of the radial artery from the brachial artery is the most frequently encountered arterial anomaly in an upper extremity, and is reported in seven percent of individuals. This variant is vulnerable to injury because of its more superficial location. A 59-year-old man developed a pseudoaneurysm following the inadvertent cannulation of a high origin radial artery. We report the successful treatment of the pseudoaneurysm by ultrasound-guided compression. Ultrasound-guided compression is an available and simple method for the repair of arterial pseudoaneurysms, and delayed complete thrombosis can be expected even if a residual flow remains after the initial compression.
