Postoperative coronary aneurysm treated with endovascular coiling.

We present a rare case of aneurysm formation of the circumflex coronary artery after a Bentall procedure. Implantation of a stent graft in the circumflex artery and closure of the aneurysm neck failed. An endovascular procedure was used to coil the aneurysm and prevent rupture. Further recovery was uneventful. Angiography did not reveal flow in the aneurysmal sack 22 months after the procedure. To our knowledge, this is the first described case of coiling a postoperative coronary artery aneurysm with an almost 2-year follow-up.
