[Management of remaining coronary artery dissection after the replacement of the ascending aorta in acute type A aortic dissection].

The authors report a case study of a 54-year-old male admitted to our hospital with severe chest pain and ST depression in II, III and aVf lead on the electrocardiogram. The chest X-ray showed an enlarged superior mediastinum. An enhanced computed tomography (CT) was performed and confirmed the diagnosis of acute type A aortic dissection. The patient underwent emergency surgical repair with the replacement of the ascending aorta. The patient recovered without complication until the fifteenth postoperative day, when another severe chest pain appeared. Emergency coronary angiography revealed a remaining dissection in both the left anterior descending artery (LAD) and the left circumflex artery (LCx). Implantation of Elite stents to the LAD and the LCx was performed. The patient recovered uneventfully after this operation. Remaining coronary artery dissection after the replacement of the ascending aorta is very rare. In this case coronary intervention with Elite stents was effective.
