title: Emergency coronary artery bypass grafting after left coronary artery rupture: a case report.
abstract: Coronary artery rupture has been known as one of the complications of coronary balloon angioplasty. In this report, we describe a case of coronary artery rupture, who underwent emergency surgery for hemostasis and coronary revascularization. A 67-year-old-male with frequent angina attacks was admitted to our institution for possible coronary angioplasty. Coronary angiogram showed diffuse disease of the mid left anterior descending artery (LAD), with two 90% stenosis. Conventional balloon angioplasty was performed, however, coronary artery rupture occurred while the stent was expanded with a 3.5 mm balloon catheter. Though pericardial drainage improved his hemodynamic state, subsequent coronary angiogram revealed leakage of contrast medium. Emergency surgery was determined at this point for hemostasis and revascularization of the LAD. The revascularization was completed with the left internal thoracic artery (LITA) to the LAD. On the contrary, since the epicardial hemorrhage around the proximal LAD did not spread any further after systemic heparinization, the epicardial surface was covered with a piece of oxidazed cellulose and fibrin glue. After the surgery, the hemodynamic state improved gradually. Postoperative coronary angiogram revealed an aneurysm of the LAD, as well as excellent LITA-LAD patency.
