目的：探讨先天性下腔静脉畸形的 CT 表现与特征。方法收集本院34例下腔静脉先天畸形，对其 CT 表现进行回顾性分析并探讨其临床意义。结果下腔静脉畸形34例中，单纯下腔静脉肝段缺如14例，双下腔静脉畸形伴下腔静脉肝段缺如3例，左位下腔静脉伴下腔静脉肝段缺如3例，环主动脉左肾静脉2例，主动脉后左肾静脉1例，下腔静脉异常引流入左心房4例，左位下腔静脉并部分异常汇入左心房1例，肝静脉高位插入1例，肝左静脉异常引流4例，下腔静脉肝段、右肾前段缺如1例。结论多层螺旋 CT 可清晰显示下腔静脉及其属支的畸形并能明确诊断，对临床诊疗有积极的指导意义。

Objective To study the features of congenital malformation of inferior vena cava (IVC)on CT.Methods CT scans of 34 patients with malformation of IVC were retrospectively analyzed and clinical significance was discussed.Results among 34 cases, 14 cases presented as simple deficiency of retrohepatic segment of IVC,3 cases presented as double IVC with deficiency of retrohe-patic segment of IVC,3 cases were left IVC with deficiency of retrohepatic segment of IVC,2 cases were circumaortic left renal vein,1 case was retroaortic left renal vein,4 cases were IVC drain into left atrium,1 case was left IVC with partial anomalous con-nection to left atrium,1 case was hepatic vein drian into right atrium directly,4 cases were left hepatic vein anomalous connection, 1 case was deficiency of IVC between hepatic and renal hilum.Conclusion MSCT can clearly demonstrate malformations of inferior vena cava and its tributaries which is important for the guidance of diagnose and therapy.
