A 55 year old woman had an extremely rare congenital anomaly of the coronary circulation in which the left anterior descending coronary artery arose from the pulmonary artery. Proximal ligation and saphenous vein grafting to the aberrant vessel were performed. Five month and 3 year angiographic follow-up studies demonstrated 1) a widely patent vein graft, 2) regression of large collateral vessels between the right coronary and circumflex arteries and the left anterior descending artery, and 3) marked attenuation of the distal right coronary and left circumflex arteries on the 3 year study. This report describes the clinical course of the oldest reported patient with this unique coronary artery anomaly and the only angiographic study of the effect of ligation and saphenous bypass grafting on its natural history.
一名55岁女性患有极为罕见的冠状动脉循环先天性异常，其左前降支冠状动脉起源于肺动脉。对异常血管进行了近端结扎并移植大隐静脉。5个月和3年的血管造影随访研究显示：1）静脉移植血管广泛通畅；2）右冠状动脉与左旋支动脉以及左前降支动脉之间的大侧支血管消退；3）在3年的研究中，右冠状动脉远端和左旋支动脉明显变细。本报告描述了有此独特冠状动脉异常的年龄最大的已报道患者的临床病程，以及关于结扎和大隐静脉旁路移植对其自然病程影响的唯一血管造影研究。
