passages.text: Formation of coronary aneurysm is a rare complication of stenting with bare metal stents, but based on experimental studies drug-eluting stents may induce toxic effects on the vessel wall with incomplete stent apposition, aneurysm formation and with the potential of stent thrombosis or vessel rupture. We present a 43-year-old man who developed a coronary aneurysm in the right coronary artery 6 months after receiving a paclitaxel-eluting stent. The patient was asymptomatic and the aneurysm was detected in a routine control. Angiography and intracoronary ultrasound demonstrated lack of contact between stent and vessel wall in a 15-mm long segment with maximal aneurysm diameter of 6.0 mm. The patient was successfully treated with a graft stent.
