A Ithough uncommon, formation of pseudoaneurysms in the brachial artery has been reported for many large series dealing with brachial artery injury after cardiac catheterization [1-3]. Sonographically guided repair of femoral artery pseudoaneurysms has become well established, with reported overall success rates ranging from 67% [4] to 90% [5]. This approach to pseudoaneurysm repair has also been reported to be successful for the treatment of brachial artery pseudoaneurysms [6, 7]. Recently, treatment of femoral artery pseudoaneurysms by direct thrombin injection under sonographic guidance has been introduced. This quick, simple procedure lacks the discomfort of sonographically guided compression and, although the number of reported cases is small, appears to have a success rate greater than 95% [8, 9]. We have successfully used sonographically guided direct thrombin injection for the repair of brachial artery pseudoaneurysms.
