Three children with repaired omphalocele underwent diagnostic cardiac catheterization. In addition to intracardiac shunts, each was found to have marked angulation at the junction of the inferior vena cava and the right atrium. After review of our autopsy material following omphalocele repair, it is suggested that the inferior vena cava - right atrial angulation is due to gradual abnormal fixation of this junction either in utero or related to the surgical repair. A change in current surgical therapy is NOT recommended. Angulation of the inferior vena cava - right atrial junction is potentially important because a) it may interfere with venous cardiac catheterization from "below", b) it poses a danger to inferior vena caval cannulation for cardio-pulmonary by-pass, and c) it may become obstructive with time producing portal hypertension.
三名接受过脐膨出修补术的儿童接受了诊断性心导管检查。除心内分流外，每例均发现下腔静脉与右心房交界处有明显成角。在对脐膨出修补术后的尸检材料进行审查后，提示下腔静脉 - 右心房成角是由于该交界处要么在子宫内逐渐出现异常固定，要么与手术修复有关。不建议改变当前的手术治疗方法。下腔静脉 - 右心房交界处的成角可能很重要，原因如下：a）它可能会干扰从“下方”进行的静脉心导管检查；b）它对用于体外循环的下腔静脉插管构成危险；c）随着时间的推移它可能会变得阻塞，从而导致门静脉高压。
