Abstract
Formation of coronary artery pseudoaneurysm after percutaneous coronary intervention is rarely reported. A close review of available literature indicates a trend of growing incidence in recent times. Here, we present a case of coronary pseudoaneurysm developing in the left circumflex artery within 50 days of sirolimus-eluting stent implantation in a 47-year-old man who was treated for triple-vessel coronary artery disease. Initially, the patient refused any further treatment. However, considering the rapid growth of pseudoaneurysm and increased severity of symptoms at subsequent follow-up, we decided to treat giant pseudoaneurysm with embolization coils. The procedure was successful and the patient remained asymptomatic thereafter.
Highlights
Development of coronary artery aneurysm after percutaneous coronary intervention is a rare entity, with reported incidence of about 0.3% to 6.0%
A study has reported that the incidence of coronary aneurysm after DES implantation is more common in left anterior descending artery (LAD), followed by right coronary artery (RCA), and rarely in left circumflex artery (LCX) [4]
We are reporting a case of coronary pseudoaneurysm developing in LCX vessel within 50 days of DES implantation in a 47-year-old man, who was successfully managed with embolization coils
Summary
Development of coronary artery aneurysm after percutaneous coronary intervention is a rare entity, with reported incidence of about 0.3% to 6.0%. Majority of these aneurysms are suspected to be pseudoaneurysm rather than true aneurysm [1]. A close review of available literature suggests a growing incidence of coronary artery aneurysms after implantation of drug-eluting stent (DES) in recent times. A study has reported that the incidence of coronary aneurysm after DES implantation is more common in left anterior descending artery (LAD), followed by right coronary artery (RCA), and rarely in left circumflex artery (LCX) [4]. We are reporting a case of coronary pseudoaneurysm developing in LCX vessel within 50 days of DES implantation in a 47-year-old man, who was successfully managed with embolization coils
