A Surgical Approach to the Repair of a False Aneurysm in the Left Main Trunk, Using Transection of the Main Pulmonary Artery / 日本心臓血管外科学会雑誌

ABSTRACT

A false aneurysm in a coronary anastomotic region is known to be an important complication after a modified Bentall procedure. We report a successful case of a 40-year-old woman in whom we performed repair of a false aneurysm in the left main trunk (LMT), using transection of the main pulmonary artery. The modified Bentall procedure and coronary artery bypass grafting (CABG) on the right coronary artery had been performed 6 years earlier, with diagnoses of Marfan syndrome, annuloaortic ectasia, aortic regurgitation, aortic dissection (DeBakey type II), and right ventricular infarction. The patient was admitted with a syncopal attack, and we diagnosed a false aneurysm in the anastomotic region of the left coronary artery. Repair of the LMT and CABG on the left anterior descending coronary artery with the left internal thoracic artery (LITA-RAD) was performed. For repair of the LMT, we used a surgical approach using transection of the main pulmonary artery to create a favorable surgical field.
