[Persistence of right umbilical vein--a rare vascular abnormality of the umbilical cord].
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.
