[Spontaneous coronary artery dissection: a case report and a review of literature].

: Operative cases of spontaneous coronary artery dissection have rarely been reported. We report an operative case of spontaneous right coronary artery dissection. The patient was a 60-year-old man with a history of angina pectoris. A selective coronary angiography demonstrated the dissection of right coronary artery #2-#3 and the stenosis in both 4 postero-lateral branch and left anterior descending artery. He was successfully managed with aorta-coronary bypass. Postoperative coronary angiography revealed the existence of dissecting lesion, however the native RCA flow was improved.
