Abstract:
The objective of this study was to prospectively evaluate the efficacy of ultrasound-guided thrombin injection for the treatment of post-catheterization femoral artery pseudoaneurysms. Between August 1, 1998 and August 31, 1999, 38 patients underwent ultrasound-guided injection of thrombin into 39 femoral false aneurysms. Peripheral pulses and ankle/brachial indices were assessed before and after the injection. Patients were followed with a control duplex scan within 4 weeks. The good results from this study showed that ultrasound-guided thrombin injection is an effective method for the treatment of post-catheterization false aneurysms. In a minority of patients, signs consistent with arterial embolization or vasospasm were identified.
