摘　　要：目的:了解单脐动脉胎儿的转归,围生结局及处理方式。方法:回顾我院近4年170例单脐动脉胎儿的临床资料(经超声、MRI、羊水或脐血染色体检查、引产胎儿尸体解剖结果等),随访出生后婴儿情况并进行临床评估及分析。结果:单脐动脉合并其他结构畸形的发生率为49.3%,合并一种畸形的发生率为15.9%,合并多种畸形发生率为33.3%;单脐动脉胎儿合并染色体异常发生率为18.4%;行MRI检查37例,与超声结果相符29例,8例与超声结果有差异,与超声符合率为78.4%。结论:超声检查易早期诊断单脐动脉,单脐动脉具有胎儿畸形的高风险性。单脐动脉合并其他结构畸形者建议行胎儿染色体检查。超声、染色体检查诊断未发现合并畸形的胎儿出生后仍有异常可能。单脐动脉不是剖宫产指征。Objective：To study the prognosis,perinatal outcome and treatment method of fetal single umbilical artery （SUA）. Methods：The clinical data of 170 fetuses with single umbilical artery admitted to our hospital in the last four years were retrospectively reviewed. Ultrasound,nuclear magnetic resonance imaging （MRI）,chromosome examination from amniotic or umbilical cord and autopsy from abortion fetus were used for diagnosis of SUA. Follow-up was done upon live fetus after parturition. Results：One hundred and seventy fetuses with single umbilical artery were detected,the incidence was 0.9%.The incidence of SUA complicated with other abnormities was 49.5%,in which the incidence of complicating one and multiple abnormities was 15.9 % and 33.3%,respectively. The incidence of SUA complicated with abnormal chromosome was 18.4%.Thirty-seven fetuses with SUA were examined by MRI,in which twenty-nine were consistent with ultrasound results,the coincidence was 78.4%. Conclusions：Ultrasound can early diagnose SUA. Fetus with SUA has high risk of abnormality. Fetus with SUA and complicated with other abnormities should receive chromosome examination. Even ultrasound result and chromosome are normal,fetal anomaly may still occur. SUA is not the indication of cesarean section.
