摘要
目的研究分析导致胎儿脐动脉舒张末期血流断流的相关因素。方法将2010年5月—2016年7月出现脐动脉舒张末期血流断流的48例孕妇作为研究对象。所有孕妇均经超声检查确诊为脐动脉舒张末期血流断流。48例孕妇中,年龄最小者为20岁,最大者为38岁,平均年龄为(28.6±1.7)岁,孕周最短者为29周,最长者为38周,平均孕周为(34.5±0.8)周,48例孕妇9例收住本院产科治疗,39例转诊至上级医院治疗,全部进行电话或现场随访追踪,对其治疗后的效果和胎儿结果进行追踪汇总分析。结果 48例孕妇中,有9例经治疗胎儿脐动脉血流恢复正常S/D<3,有20例脐动脉舒张期可探及血流S/D>3,仍有19例无明显改善;胎儿结局方面,有1例胎儿畸形引产,有1例双胎妊娠一胎胎儿畸形胎死宫内,有2例新生儿窒息,其余44例结局良好。结论胎儿脐动脉舒张末期血流断流可导致胎儿在宫内发生缺氧状况,若不及时加以干预,围产儿死亡率高、新生儿窒息率高、早产率高、低体重儿几率高,胎儿脐动脉血流频谱舒张末期血流缺失或倒置提示胎儿随时有胎死宫内的危险,应该积极处理。
Objective To investigate the related factors of 48 cases of blood flow cutoff during the end-diastolic phase of fetal umbilical artery.Methods 48 cases of delivery women with blood flow cutoff during the end-diastolic phase of fetal umbilical artery admitted and treated in our hospital from May 2010 to July 2016 were selected as the research objects,all delivery women underwent the examination,and of 48 cases,the age was from 20 to 38 years old,(28.6±1.7)years old on average,and the pregnant week was from 29 to 38 weeks,(34.5±0.8)weeks on average,and 9 cases were admitted to the department of gynecology of 48 cases,39 cases were transferred to the upper hospital for treatment,all patients were for telephone follow-up and tracing on filed,and the treatment effect and fetal results were summarized and analyzed.Results Of 48 cases,9 cases recovered to normal S/D<3,the blood flow of 20 cases with diastolic phase of fetal umbilical artery could be probed S/D>3,19 cases had no obvious improvement,in terms of fetal outcome,1 case had the induction of fetal malformation,1 case had bigeminal pregnancy,2 cases had asphyxia neonatorum,and the outcomes of 44 cases were good.Conclusion The blood flow cutoff during the end-diastolic phase of fetal umbilical artery can lead to intrauterine hypoxia,if the intervention is not conducted in time,the high perinatal mortality,high asphyxia neonatorum rate,high premature birth rate,high low birth weight infants and blood flow loss or inversion of umbilical artery blood flow spectrum of fetus during the end-diastolic phase remind the risk of the intrauterine fetal death that should be handled actively.
