摘要
目的分析合并帆状胎盘时妊娠不良结局与产前超声检查脐动脉血流收缩期峰值流速和舒张末期流速比值(S/D)的相关性。方法对经临床及病理检查证实的90例单胎妊娠合并帆状胎盘产妇的产前超声检查结果及临床资料进行回顾性分析,根据彩色多普勒超声检查脐动脉血流S/D测值将病例分为S/D增高组及S/D正常组(对照组),就产妇特征、新生儿出生体重及妊娠不良结局发生率比较组间差异。结果脐动脉血流S/D增高组21例,S/D正常组69例。S/D增高组平均新生儿出生体重(2603.8±834.5)g,低于对照组平均新生儿出生体重(3164.0±436.6)g,差异具有统计学意义(P<0.01)。S/D增高组的胎儿宫内窘迫所致急诊剖宫产率(9/21,42.9%)、早产发生率(7/21,33.3%)、小于孕龄儿出生率(10/21,47.6%)、新生儿低Apgar评分发生率(4/21,19.0%)这4项指标均高于对照组,差异具有统计学意义(P<0.01)。结论当产前超声检查提示帆状胎盘时,脐动脉血流S/D可被认为是预测妊娠结局的有效指标。
Objective To evaluate the role of umbilical artery Doppler ultrasound as a predictive marker of pregnancy outcome in patients with velamentous cord insertion （VCI）. Methods The prenatal color Doppler ultrasound findings and clinical data in 90 patients with singleton pregnancies with clinically and pathologically diagnosed as VCI were retrospectively reviewed. The cases were divided into elevated S/D group and control group according to the ratio of peak-systolic to end-diastolic blood flow velocities （S/D） in the umbilical artery. Maternal characteristics, birth weight and incidence of adverse pregnancy outcome were compared between groups. Results The S/D of umbilical artery were elevated in 21 cases and normal in 69 cases. Mean birth weight in elevated Slid group （2603.8 ＋ 834.5 ） g was lower than those in control group （3164.0 ＋ 436.6） g, and the difference was statistically significant （P 〈 0.01 ）. In elevated S/D group, the incidences of emergency cesarean section caused by feta! distress （9/21,42.9%） , preterm birth cases （7/21,33.3%）, small for gestational age infants （ 10/21,47.6% ） and low Apgar score （4/21,19.0%） in elevated S/D group were higher than those in the control group with statistically significant difference （P 〈 0.01 ）. Conclusion The S/D of umbilical artery is recommended to be used as an effective predictor of pregnancy outcome in diagnosis of VCI during prenatal ultrasound examination.
