Coil embolization of pseudoaneurysm as a complication of excimer laser coronary angioplasty: insights from intravascular ultrasound and optical coherence tomography findings.

The occurrence of pseudoaneurysm in the coronary artery is rare and can develop after percutaneous coronary interventions. To date, the optimal therapy, including conservative, surgical, and endovascular therapies, for pseudoaneurysm in the coronary artery remains unclear. Here, we report a case of pseudoaneurysm arising as a complication of excimer laser coronary angioplasty, which was successfully treated with stent-assisted coil embolization, after which optical coherence tomography revealed complete healing of the pseudoaneurysm. This report highlights the feasibility of stent-assisted coil embolization for coronary pseudoaneurysms involving bifurcation.
