Key result
Drug-eluting stent implantation at a coronary artery injury site may have delayed healing and remodeling, contributing to the reexpansion of a pseudoaneurysm after one year.
Case Report (n=1)
Drug-eluting stent implantation at a coronary artery injury site may delay healing and contribute to the reexpansion of a pseudoaneurysm.
May warrant caution with DES at coronary injury sites; leaves open whether delayed healing drives pseudoaneurysm reexpansion.
A 73-year-old man with 2-vessel coronary artery disease underwent a staged percutaneous coronary intervention that resulted in rupture of the right coronary artery and pseudoaneurysm formation. Although the pseudoaneurysm regressed over a week, it reexpanded after a year. Resection of the pseudoaneurysm and coronary artery bypass grafting were performed. The drug-eluting stent at the coronary artery injury site may have delayed healing and remodeling of the artery, thus contributing to reexpansion of the pseudoaneurysm.

Hori et al. (2013) conducted a case report in Coronary artery pseudoaneurysm (n=1). Drug-eluting stent implantation was evaluated on Pseudoaneurysm reexpansion. Drug-eluting stent implantation at a coronary artery injury site may have delayed healing and remodeling, contributing to the reexpansion of a pseudoaneurysm after one year.
