Lee, Jeon, Hong, Cho, and Kim: Balloon-Assisted Ultrasound-Guided Thrombin Injection of a Pseudoaneurysm in the Posterior Tibial Artery: A Case Report

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.

Figures and Tables

Angiogram shows contrast outpouching lesion (arrow), consistent with pseudoaneurysm in distal right posterior tibial artery.

21-G Chiba needle (arrow) was inserted in the pseudoaneurysm under ultrasound guidance after occlusion of flow with 2.5 mm balloon (arrowhead).

Color Doppler ultrasound shows disappearance of abnormal color flow and the thrombus completely filling the pseudoaneurysm.
