title: Aneurysm formation after drug-eluting balloon treatment of drug-eluting in-stent restenosis: first case report.
abstract: A 55-year-old male underwent paclitaxel-eluting stent implantation in a bifurcation lesion of his left anterior descending artery (LAD) during an episode of unstable angina in 2008. A late in-stent restenosis developed 15 months after implantation of the drug-eluting stent (DES) and was treated with paclitaxel eluting balloon. Two months later, during angiography for functional assessment of the significance of lesions in the circumflex artery, an aneurysm at the place of drug-eluting balloon (DEB) inflation was observed. The patient was left on double antiplatelet therapy and scheduled for clinical observation after 3 months and control coronary angiography after 6 months for aneurysm progression follow-up.
