Treatment of Radial Artery Pseudoaneurysm Using a Novel Compression Device.

Michael Liou, Frank Tung, Yumiko Kanei, Tak Kwan.

ABSTRACT:Radial artery pseudoaneurysm is an extremely rare complication associated with transradial catheterization. We report 2 cases of pseudoaneurysm of the radial artery that were successfully treated using the Terumo TR band. We believe that the safety, efficiency, speed and minimal invasiveness of this method make it feasible for use as a treatment for peripheral pseudoaneurysm in such patients.

The transradial approach for coronary angiography and interventions has become increasingly popular as an attractive alternative to the femoral approach because of its clinical benefits. Pseudoaneurysm (PA) of the radial artery is an extremely rare complication associated with this procedure and is most often localized in the area of penetrating vascular trauma. Current methods of treatment for radial artery PA are adopted from those of femoral artery PA, including ultrasound-guided compression, percutaneous thrombin injection and surgical repair.1 We propose the use of a novel compression device specifically designed for radial artery hemostasis called the TR Band (Terumo®, Tokyo, Japan) as a safe and effective modality for the treatment of radial artery PA. We present 2 cases of radial artery PA after transradial catheterization, both resolved by using the TR Band. To our knowledge, this has not been previously reported among conservative treatment approaches to the management of radial artery PA.
