Percutaneous Thrombin Injection with Balloon Occlusion for the Treatment of a Femoral Artery Pseudoaneurysm / 대한내과학회지

ABSTRACT

Femoral artery pseudoaneurysm (FAP) is an uncommon but potentially serious vascular complication that may develop after cardiac and peripheral angiographic procedures. Here we describe the case of a 75-year-old female who presented with a life-threatening bleeding episode due to an FAP 4 days after diagnostic coronary angiography, which was treated with a percutaneous thrombin injection and transient balloon occlusion of the femoral artery during thrombin injection. This case reminds us of the importance of close observation and proper evaluation for complications, even if the risk of bleeding complications is low. Furthermore, although ultrasound-guided compression and a percutaneous thrombin injection are the standard treatment for FAP, this case demonstrates that transient balloon dilation during the percutaneous injection of thrombin is an important treatment option in cases of a wide-necked pseudoaneurysm in which the risk of thrombin escape is high.
