[Ultrasound-guided percutaneous thrombin injection therapy for the treatment of iatrogenic brachial pseudoaneurysms].

Iatrogenic pseudoaneurysm could result in rupture or serious complications. The treatment of this condition involves the use of ultrasound-guided compression therapy;however, when this therapy is not effective, surgical intervention becomes necessary. Although ultrasound-guided compression therapy is a minimally invasive treatment, the patient might experience pain during the procedure and its effectiveness is decreased under anticoagulant therapy. Surgical repair is also invasive and is frequently accompanied by several complications. We successfully treated 3 cases of iatrogenic pseudoaneurysm on the brachial artery (size, 25~45mm) using the ultrasound-guided thrombin injection therapy after the ultrasound-guided compression therapy was unsuccessful. Ultrasound-guided thrombin injection therapy is an alternative treatment that is highly effective with the additional advantage of being a simple and quick procedure with lesser burden on the patient.
