摘　　要：目的分析产前超声对血管前置的诊断价值,并分析预后。方法回顾性分析2018年1月-2022年10月于江西省妇幼保健院经手术及病理证实的41例血管前置孕妇临床资料,全部孕妇均接受产前超声检查,查阅资料,计算产前超声对血管前置的检出率,比较孕中期、孕晚期血管前置的检出情况;并记录血管前置的产前超声图像;进行病例追踪,分析血管前置孕妇的妊娠结局、预后情况。结果经手术及病例证实的41例血管前置病例中,产前超声共检出38例血管前置,检出率为92.68%;其中有24例孕中期首诊(63.16%),14例孕晚期首诊(36.84%);24例于孕中期首诊为血管前置孕妇,同时进行孕晚期超声检查,结果显示,孕中期血管前置的检出率高于孕晚期,差异有统计学意义(P<0.05)。38例经超声诊断为血管前置的孕妇均行剖宫产术分娩,其中5例急诊剖宫产,剩余33例孕妇均择期行剖宫产术,母婴预后良好;该组病例中,足月儿16例、>34周早产儿22例、≤34周早产儿3例。结论产前超声能够有效检出血管前置,其中孕中期诊断是最佳时间,可提高检出率;孕妇经剖宫产术分娩后母胎预后良好。Objective To analyze the diagnostic value of prenatal ultrasound in vascular previa and to analyze the prognosis.Methods Clinical data of 41 pregnant women with vascular previa confirmed by surgery and pathology in our hospital from January 2018 to October 2022 were collected.All pregnant women underwent prenatal ultrasound examination.The data were consulted,and the detection rate of vascular previa by prenatal ultrasound was calculated,and the detection situation of vascular previa in the second and third trimesters was compared.Prenatal ultrasound images of vascular previa were recorded.The pregnancy outcome and prognosis of pregnant women with vascular previa were analyzed by case tracking.Results Among 41 cases of vascular previa confirmed by operation and case,38 cases were detected by prenatal ultrasonography,the detection rate was 92.68%.There were 24 cases(63.16%)in the second trimester and 14 cases(36.84%)in the third trimester.24 cases were first diagnosed as vascular previa in the second trimester,and ultrasound examination in the third trimester showed that the detection rate of vascular previa in the second trimester was higher than that in the third trimester,and the difference was statistically significant(P<0.05).38 pregnant women diagnosed with vascular previa by ultrasound underwent cesarean section for delivery,including 5 cases of emergency cesarean section,and the remaining 33 cases were delivered by cesarean section at selected time,and the prognosis was good.There were 16 full-term infants,22 preterm infants>34 weeks,and 3 preterm infants≤34 weeks.Conclusion Prenatal ultrasound can effectively detect vascular previa,and the second trimester diagnosis is the best time to improve the detection rate.The prognosis of mother and fetus after delivery by cesarean section is good.
