Thrombin injection is frequently used to occlude iatrogenic pseudoaneurysms in larger vessels, but has never successfully been used in the radial artery location. Here we report the use of this treatment in a patient with radial artery pseudoaneurysm following coronary intervention. After Doppler sonographic visualization of the pseudoaneurysm cavity and its neck, an ultrasound-guided transcutaneous injection of thrombin was carried out. Immediately after the injection, the pseudoaneurysm was completely clotted and Doppler measurement confirmed the stop of blood flow. The result suggests that ultrasound-guided injection of thrombin into a radial artery pseudoaneurysm following coronary intervention is a feasible alternative to surgical intervention.
