Abstract

A high systolic/diastolic (S/D) ratio of umbilical cord blood is a manifestation of intrauterine hypoxia. However, the clinical significance of a persistently decreased S/D ratio of umbilical cord blood has not been reported. We report eight cases of a persistently decreased S/D ratio of umbilical cord blood, with two cases of umbilical thrombus, five cases of excessive torsion, and one case of a true cord knot. Fetuses with a persistently decreased S/D ratio of umbilical cord blood may be at risk, and it may be an important indication of umbilical cord lesions.

摘要

脐血高收缩期/舒张期（S/D）比值是宫内缺氧的一种表现。然而，脐血S/D比值持续降低的临床意义尚未见报道。我们报告了8例脐血S/D比值持续降低的病例，其中2例为脐血栓，5例为过度扭转，1例为真性脐带打结。脐血S/D比值持续降低的胎儿可能处于危险中，这可能是脐带病变的一个重要指征。
