We report on a persistent V. umbilicalis dextra as an extrem rare anomaly of the vessels of the umbilical cord and its embryological base. The compression of this umbilical cord was responsible for the emergence of abnormal QRS-complexes in the fetal electrocardiogram according to typus 2 by Larks. To detect these anomalies of vessels should be investigated on princip every umbilical cord.
我们报告了一例持续性右侧脐静脉，这是一种极其罕见的脐带血管异常及其胚胎学基础。根据拉克斯的2型，这种脐带受压导致胎儿心电图中出现异常QRS复合波。原则上，应对每一条脐带进行检查，以检测这些血管异常。
