成人左冠状動脈肺動脈起始症に対する大伏在静脈を用いた再建の1例

Reconstruction Using a Saphenous Vein for Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery in an Adult；Report of a Case

はじめに　成人左冠状動脈肺動脈起始症（ALCAPA）はまれな疾患であり，外科的再建法において一定した見解はない．われわれは大伏在静脈（SVG）によるinterposition法を用いて良好な結果を得たので報告する．

Anomalous left coronary artery from the pulmonary artery （ALCAPA） is an uncommon congenital heart disease. Such anomaly causes myocardial ischemia, heart failure, and sudden death. Most of such cases require surgical intervention. We report a successful surgical correction for ALCAPA in an adult. A 31-year-old woman with progressive exertional dyspnea was referred to our institution because of abnormal electrocardiogram showing ST depression （V3～V6）. Computed tomography revealed the left main trunk （LMT） arising at the right lateral wall of the main pulmonary trunk. Interposition of a saphenous vein graft was performed between the ascending aorta and the LMT. The postoperative course was uneventful.
