Recurrence following percutaneous exclusion of giant coronary pseudoaneurysm: a case report

In this case, vessel wall injury as a result of aggressive post dilatation using an oversized balloon during the index procedure was the contributor to the giant coronary PSA formation. It usually appears early after the index procedure (within 4 weeks). Though the usual strategy used to exclude coronary aneurysm is by using the minimal number of stent grafts (due to the inherent increased risk of restenosis/thrombosis in stent grafts) in post angioplasty traumatic aneurysm it is prudent to exclude the entire damaged artery by placing stent grafts to prevent recurrence in segments with even minimal dilatation on initial evaluation.
