Treatment of femoral artery pseudoaneurysms using ultrasound-guided thrombin injection

Femoral artery pseudoaneurysms, a complication of femoral arterial puncture, is increasing in frequency with the proliferation of endovacular interventions. Pseudoaneurysms have historically been treated by open surgical repair, and more recently by ultrasound-guided compression. Ultrasound-guided compression is painful, and has a relatively low success rate of 51% to 73%. Since 1991, ultrasound-guided thrombin injection has become a treatment option. During injection of thrombin into a pseudoaneurysm, immediate thrombosis can be demonstrated within seconds. The entire procedure can be accomplished within 5 minutes, is simple to learn, and can be performed safely on an outpatient basis. © 2003 Elsevier Inc. All rights reserved.
