摘要
目的:评价MRI对马凡综合征心血管病变的诊断价值和限度,明确MRI在制定手术方案中的作用。材料和方法:35例患者行MRI自旋回波和电影扫描,马凡综合征的诊断由心血管、肌肉骨骼或眼的异常改变和家族史确立。MRI的结果与50例正常志愿者和50例高血压病者进行对比。结果:马凡综合征的主要MRI征象如下:(1)主动脉窦和升主动脉根部瘤样扩张(100.0%),在左斜和(或)冠、矢状断面上呈大蒜头样(74.3%)。(2)左心房受压变扁(88.6%)。(3)左心室扩大(60.0%)和左室壁增厚(34.3%)。(4)电影MRI准确显示主动脉瓣关闭不全。(5)可见马凡综合征的并发症,包括主动脉夹层(4例)、心包积液(3例)和胸腔积液(1例)。14例患者未行X线血管造影检查,根据MRI所见成功施行了手术,全部患者存活。结论:马凡综合征的MRI所见有特征性,MRI能取代X线血管造影制定手术方案。
