Abstract

A 59-year-old man with acute cholangitis was referred to us because of a coronary artery aneurysm that was incidentally detected on contrast-enhanced computed tomography. Intravascular ultrasonography showed a loss of vascular layers and complete stent fracture, which was suggestive of a pseudoaneurysm. After some management protocols, such as observation, covered stent implantation, and surgical treatment, had failed, we treated the pseudoaneurysm successfully using coil embolization and a vascular plug. There were no complications during the perioperative period. We suggest that, if conventional management fails, treatment with coil embolization and a vascular plug should be considered.

Learning objective

A rare complication of percutaneous coronary intervention resulting from stent fracture is a coronary artery aneurysm. Here, we discuss the chronic complications of stent implantation and discuss the optimal management strategy for coronary pseudoaneurysms. Further, we discuss the strengths and weaknesses of each strategy.
