Abstract

The aim of this study was to assess the safety and efficacy of ultrasound-guided percutaneous thrombin injection for the treatment of postcatheterization arterial pseudoaneurysms. We evaluated retrospectively 82 consecutive subjects treated with percutaneous ultrasound-guided thrombin injection of postcatheterization femoral (n = 79), brachial (n = 2), and radial (n = 1) pseudoaneurysms from January 2006 to April 2012. Pseudoaneurysm size, thrombin dose, and therapy outcome were documented. All pseudoaneurysm sacs were thrombosed with a single injection. The overall primary success rate (complete sac thrombosis) was 92.7%. A 30-day Doppler ultrasound follow-up showed a 100% procedural success. There were no complications.
