【Abstract】 Objective To evaluate the efficacy and safety of ultrasound-guided percutaneous umbilical blood sampling. Methods Eight hundred and seventy-two pregnancies with proper indications underwent ultrasound-guided percutaneous umbilical sampling. The data of each procedure were prospectively collected and subsequently analyzed for successful rate and pregnancy outcomes. Results Of 872 ultrasound-guided percutaneous umbilical sampling, 62.7% were done successfully at the first attempt, 36.0% were done successfully by two to four attempts. 31.4% fetuses had mild procedure-related complications and 0.3% fetuses had severe complications. Conclusion We should improve the efficacy and safety of ultrasound-guided percutaneous umbilical sampling and make it a correct, safe and effective procedure for prenatal diagnosis.更多还原
