【摘要】：目的探讨单羊膜囊双胎妊娠的产前超声特征。方法回顾性分析40例单羊膜囊双胎妊娠的产前超声声像图特征与产后结局。结果产前超声共检出40例单羊膜囊双胎妊娠,均经产后证实。胎儿畸形发生率为47.5%(19/40),其中双胎反向动脉灌注序列征7例(17.5%);联体双胎5例(12.5%),均为胸脐联胎;双胎腹裂1例(2.5%),胎儿心脏发育异常5例(12.5%),单一胎儿露脑畸形1例(2.5%)。胎死宫内4例,占妊娠总数的10%,其中2例脐带缠绕,2周后复查,均胎死宫内。除胎儿心脏发育异常双胎引产后未做尸解,余均引产后证实。仅17例(42.5%)单羊膜囊双胎妊娠胎儿产前超声检查未见异常。结论单羊膜囊双胎妊娠的胎儿畸形发生率及病死率较高,通过孕早期的超声检查对单羊膜囊双胎妊娠进行早期诊断,中孕期进行胎儿畸形筛查并加强中晚孕期超声监测,降低畸形胎儿出生率及胎儿病死率。
[Abstract]:Objective to investigate the characteristics of prenatal ultrasound in single amniotic sac twin pregnancy. Methods 40 cases of single amniotic sac twin pregnancy were analyzed retrospectively. The incidence of fetal malformation was 47. 5% and 19 / 40% respectively, in which 7 cases had reverse arterial perfusion sequence sign of twins, 5 cases of conjoined twins were associated with thoracic and umbilical cord, and 5 cases of conjoined twins were associated with thorax and umbilical cord. There were 1 case with abdominal fissure, 5 cases with abnormal development of fetal heart, 1 case with single fetal dew-brain malformation, 4 cases with intrauterine fetal death, accounting for 10% of the total number of pregnancies, 2 cases with umbilical cord twining were reviewed after 2 weeks. All were born dead in the uterus. No autopsy was done after induced labor of the twins with abnormal fetal heart development. Only 17 cases of single amniotic capsule twin pregnancy had no abnormal prenatal ultrasound examination. Conclusion the fetal malformation rate and mortality rate of single amniotic capsule twin pregnancy are higher than that of single amniotic capsule twin pregnancy. The early diagnosis of single amniotic sac twin pregnancy was carried out by ultrasonic examination in the early pregnancy. The fetal malformation was screened during the middle and late pregnancy and the ultrasonic monitoring during the middle and late pregnancy was strengthened to reduce the birth rate of the abnormal fetus and the fetal fatality rate.
