The first case of a patient with interrupted inferior vena cava, four post-renal veins and an azygoshemiazygos continuation is presented. The complicated anomalies were omphalocele and atrial septal defect. Cine-magnetic resonance imaging and cardiac catheterization showed an anomalous retroaortic left innominate vein, azygos-hemiazygos continuation in the prerenal portion, arch formed renal vein in the renal portion and four embryonic vessels in the post-renal portion. Combination of these anomalies in the major venous system suggested that the inferior vena cava had failed to form and that the bilateral embryonic venous system, postcardinal and supracardinal veins, persisted to be the systemic venous channels.
本文报告了一例下腔静脉中断、四条肾后静脉及奇静脉-半奇静脉延续的患者。复杂的畸形包括脐膨出和房间隔缺损。电影磁共振成像和心导管检查显示，主动脉后方存在异常的左无名静脉，肾前部分为奇静脉-半奇静脉延续，肾部分为弓状肾静脉，肾后部分有四条胚胎血管。主要静脉系统中这些异常的组合表明，下腔静脉未能形成，双侧胚胎静脉系统，即后主静脉和上心静脉，持续作为体静脉通道。
