目的:探讨胎儿脐带绕颈的超声诊断价值。方法:选取临床2010年以来超声诊断胎儿脐带绕颈的临床资料进行分析。结果:超声诊断脐带绕颈80例,经临床分娩确诊76例,准确率为96%。胎儿颈部附近可发现脐带走向与胎儿颈部长轴交叉。如脐带缠绕较紧,在纵切声像中胎儿颈项皮肤可呈现脐带的压痕,或呈“U”形(绕颈1周),或呈“W”状(绕颈2周)。结论:超声检查发现胎儿脐带绕颈,一般说不是立即剖宫产的指征,应严密观察和监控,一旦发现胎儿宫内窘迫,及时临床处理。
Objective: To investigate the diagnostic value of fetus umbilical cord around the neck. Methods: The clinical data of fetus umbilical cord around neck since 2010 were selected for clinical analysis. Results: Ultrasound diagnosis of 80 cases of umbilical cord around the neck, diagnosed by clinical delivery 76 cases, the accuracy rate was 96%. Around the neck of the fetus, the umbilical cord can be found to cross the long axis of the fetal neck. If the umbilical cord is tightly wound, the fetal neck skin may show umbilical cord indentation or “U” shape (1 week around the neck) or “W” shape around the neck for 2 weeks ). Conclusion: Ultrasound examination found that the umbilical cord around the neck, generally not an indication of immediate cesarean section should be closely observed and monitored, once found fetal distress, timely clinical treatment.
