Treatment of Iatrogenic Pseudoaneurysms Using Ultrasound-Guided Thrombin Injection over a 5-Year Period.

In this study we demonstrate that ultrasound (US)-guided injection of thrombin is a safe and effective way to treat iatrogenic pseudoaneurysms as a new treatment modality at a 650-bed urban community hospital. We included retrospective chart review of patients who were treated for iatrogenic pseudoaneurysms from January 2004 to June 2010 at a single institution. All patients' pseudoaneurysms were treated using US-guided thrombin injection. This study demonstrated an overall success rate of 97.1% in treating iatrogenic pseudoaneurysms in 33 of 34 patients. One patient underwent open surgical repair. No mortality or complications were noted. The study was successful in demonstrating that the US-guided injection of thrombin is an efficacious way to treat iatrogenic pseudoaneurysms and can be safely implemented as a new treatment modality by appropriately trained vascular surgeons. A review of different techniques is included. An algorithm for the treatment of iatrogenic pseudoaneurysms is proposed from this study.
