Radial artery pseudoaneurysm: a simplified treatment method.

A radial artery pseudoaneurysm represents a rare, potentially catastrophic complication of arterial cannulation that has been reported after cardiac catheterization. Treatment options are limited to chemical, mechanical, and combined approaches to obliterate the radial artery pseudoaneurysm and tract. Manual compression protocols using the TR Band (Terumo Medical Corporation, Somerset, NJ) have been variable and anecdotal, without objective measurements of adequate compression, making this technique prone to failure. In this report, we present an efficient, safe, and noninvasive management protocol using a pulse oximeter and the TR Band for treatment of radial artery pseudoaneurysms that is cost-effective and efficient and ensures correction without occlusion of the radial artery.
