目的探讨产前超声检查诊断血管前置的意义及方法。方法回顾性分析11例妊娠合并血管前置产前超声声像图表现及胎儿结局。结果 11例血管前置中,诊断符合7例(其中中孕诊断5例,晚孕诊断2例),择期剖宫产7例,无围产儿死亡;漏诊3例(其中中孕1例、晚孕2例),误诊2例(均为晚孕),因胎儿窘迫、孕妇阴道流血急诊剖宫产4例,其中两例新生儿窒息。结论中孕是诊断血管前置的最佳时期,经腹超声检查胎盘、胎盘脐带插入口、宫颈内口并叠加彩色多普勒是诊断血管前置的常规方法,对宫颈内口显示不满意时结合经阴道或经会阴彩色多普勒超声检查可有效降低血管前置漏诊误诊率,有效改善围产儿结局。
Objective To investigate the significance and methods of prenatal ultrasonography in the diagnosis of vascular anterior. Methods Retrospective analysis of 11 cases of prenatal ultrasound prenatal ultrasound imaging and fetal outcome. Results Among the 11 cases, the diagnosis was performed in 7 cases (5 cases were diagnosed in the second trimester and 2 cases were diagnosed in the second trimester), and 7 cases were elective cesarean. No perinatal death was found. Three cases missed diagnosis (1 in the second trimester, 2 cases of pregnancy) and 2 cases of misdiagnosis (both of which were late pregnancies). Due to fetal distress, 4 cases of emergency cesarean section were discharged by vaginal bleeding in pregnant women, of which 2 cases were neonatal asphyxia. Conclusions The second trimester of pregnancy is the best time to diagnose the blood vessel. Transabdominal ultrasonography is the routine method of diagnosing the blood vessel previa by examining the placenta, placenta umbilical cord insertion mouth, cervical internal mouth and color Doppler. Combined with transvaginal or perineal color Doppler ultrasound can effectively reduce the misdiagnosis rate of vascular anterior missed diagnosis, and effectively improve the perinatal outcome.
