目的:评价经腹旋转法脐静脉穿刺术在产前诊断胎儿染色体异常中的应用。方法:对56例孕妇在超声引导下行经腹旋转法脐静脉穿刺抽取脐血检查胎儿染色体核型,并观察手术的成功率和并发症。结果:56例脐静脉穿刺中,第一次抽不出脐静脉血、通过顺时钟旋转180°,再抽取脐静脉血成功的有20例;出现胎儿心动过缓2例,脐带出血9例。结论:经腹旋转法脐静脉穿刺术是一项安全、可靠的产前诊断技术。
Objective: To evaluate the application of transabdominal rotation umbilical vein puncture in prenatal diagnosis of fetal chromosomal abnormalities. Methods: Fifty - six pregnant women underwent ultrasound - guided umbilical cord blood transabdominal transfer to check the fetal karyotype and to observe the success rate and complications of the operation. Results: In 56 cases of umbilical vein puncture, no umbilical venous blood was drawn for the first time, and 20 cases of umbilical venous blood were drawn by clockwise rotation of 180 °. There were 2 cases of fetal bradycardia and 9 cases of umbilical cord bleeding. Conclusion: Transabdominal rotation of umbilical vein puncture is a safe and reliable prenatal diagnosis technique.
