Stent-supported angioplasty of a residual coronary artery dissection following replacement of the ascending aorta for acute type A aortic dissection. A report of a successful case.
A 54-year-old-man suddenly experienced severe back pain while eating. On admission to our hospital, contrast-enhanced computed tomography revealed an acute type A aortic dissection, and emergency surgical repair was performed the same day. Through median sternotomy, graft replacement of the ascending aorta, including removal of the site of the intimal tear, was carried out under deep hypothermia and retrograde cerebral perfusion. Although the postoperative course was satisfactory, the patient suddenly complained of sever chest pain on postoperative day 23; the ECG trace showed anomalous alterations. Emergency coronary angiography revealed the presence of a wide coronary artery dissection from the entry of the left anterior descending aorta (LAD) to the re-entry of the left circumflex artery (LCX). Multiple stents were implanted in the LAD and LCX. After stenting, the chest symptoms remitted and the ECG trace was normal. The patient was discharged from our hospital on postoperative day 42.
