Abstract
An ultrasound-guided direct injection of thrombin is currently the first choice of treatment for the postcatheterization pseudoaneurysm, mainly in the femoral artery. A pseudoaneurysm in the posterior tibial artery is very rare, so there are not enough reports about proper treatment yet. We report a case of a balloon-assisted injection of thrombin under ultrasonography-guidance to manage a pseudoaneurysm in the posterior tibial artery and concurrently to prevent a distal artery embolization.
