ABSTRACT
Objective To observe the pregnancy by transvaginal double slit cervical pregnancy outcome after ligation,and evaluate its clinical application value.Methods The clinical data of 80 cases with cervical incompe-tence were analyzed.All patients had pregnant metaphase inevitable abortion history,the average abortion pregnant was 21.7 week.According to different treatment methods,80 cases were divided into two groups,treatment group (40 cases)in non pregnant women with silk thread woven tape by double vagina and cervix cerclage,another group of 40 cases in 15 -20 weeks of pregnancy by using polypropylene McDonald method with cerclage.The operation,preg-nancy cervical tube length and pregnancy outcome were observed.Results The average operation time and bleeding volume between the two groups had no statistically significant differences.The pregnancy cervical average length of the treatment group was 4.6(4.8 ±0.5)cm,which was significantly longer than 3.9(3.1 ±0.8)cm of the control group (t =2.732,P <0.05).In the treatment group,the full -term delivery rate,preterm delivery rate,mean gestational age at delivery were 55.0%(22 /40),40.0%(16 /40),35.8 weeks,the average abortion was extended 14.1 weeks com-pared with preoperation,fetal survival rate was 90.0%(36 /40),neonatal birth weight was (3 100.0 ±200.0)g;28 gestational weeks following the inevitable abortion rate was 2.5%(1 /40).In the control group,the term delivery rate was 35.0%(14 /40),the rate of premature birth was 50.0%(20 /40),and the rate of abortion was 15.0%(6 /40)in 28 weeks.Mean gestational age at delivery was 33.2 weeks,which was extended 11.5 weeks compared with preoperative average abortion,fetal survival rate was 85.0% (34 /40),neonatal body mass was (2 900.0 ±300.0)g. The term delivery rate,fetal survival rate and neonatal weight in the treatment group were higher than those in the con-trol group.Conclusion Pregnant by double vagina and cervix cerclage treatment cervical function can maintain preg-nancy,cervical length,prolong the time of pregnancy and improve the perinatal survival rate,simple operation,take out stitches convenient,it is worthy of clinical application.
