Abstract： 目的探讨冠状动脉(简称冠脉)起源于肺动脉(ACAPA)影像学诊断方法的价值.方法回顾性分析11例ACAPA的影像学表现.11例均行X线胸片、超声心动图(Echo)和心血管造影检查,其中1例行电子束CT(EBCT)检查.结果10例为左冠脉起源于肺动脉,1例为右冠脉起源于肺动脉.11例胸片均未确诊,Echo诊断3例,EBCT诊断1例.心血管造影全部诊断正确,其中左冠脉异常起源者左冠脉均发自主肺动脉后窦或后壁,通过扩张的右冠脉藉侧支逆行充盈;右冠脉异常起源者右冠脉从主肺动脉右窦发出.手术与造影所见相同.3例前乳头肌缺血性纤维化,二尖瓣环扩大,前叶脱垂致二尖瓣关闭不全.结论X线胸片诊断受限,Echo简便、无创,但操作技术及认知水平有待提高.心血管造影仍是术前确诊的"金标准".
