[Abstract]:Objective To investigate the safety and efficacy of selective reduction of fetus with radiofrequency ablation (RFA) in the treatment of complicated multiple single chorionic pregnancy and analyze the factors influencing pregnancy outcome. The clinical data of complicated single chorionic multifetal pregnancies were recorded, including the age of the pregnant woman, the number of pregnancies, the gestational age, the mode of conception, the indication of reduction, the gestational age at the time of operation, the puncture, the number of cycles needed for the operation, the complications of mother and infant, the gestational age of delivery, the mode of delivery, the weight of the newborn and the postnatal growth and development of the fetus. Survival rate was the proportion of those who retained fetal survival in patients undergoing selective reduction by radiofrequency ablation. Factors affecting pregnancy outcome were analyzed. Differences between multiple sample rates were analyzed by Chi-square test and Fisher exact probability method. Kruskal-Wallis H-rank sum test was used to analyze multigroup measurements that did not meet the criteria for analysis of variance. Results From July 22, 2011 to March 16, 2017, a total of 71 cases of complicated multiple pregnancy received RFA treatment. Among them, 20 cases (28.2%) of triplets with single chorionic twins and above required fewer fetuses, 21 cases (29.6%) of single chorionic twins with one fetal malformation, and single chorionic twins with twin transfusion syndrome. Twenty patients (28.1%) had twin to twin transfusion syndrome (TTTS), seven patients (9.9%) had severe selective intrauterine growth restriction (sIUGR), and three patients (4.2%) had twin reversed arterial perfusion sequence (TRAP). The mean gestational age was (20.4 (+3.5) weeks (14.7-27.7 weeks). The success rate of puncture was 100% (71/71). 57 cases (71/71). One cycle was completely blocked, 11 cases needed two cycles, and 3 cycles. The average gestational age was (36.6 2.9) weeks (29.1 41.1 weeks), and the average birth weight was (2633 601) g (12.1) g (12. The preterm birth rate was 20.4% (11/54) before 34 weeks and 40.7% (22/54) before 37 weeks. No retinopathy, intracranial hemorrhage, necrotizing enterocolitis and severe neurological sequelae were found during the follow-up. Fetal survival rate, mean gestational age, average neonatal weight, abortion rate, fetal death in uterus were maintained among the groups with different surgical indications. There was no significant difference in the preterm birth rate and the preterm birth rate before 37 weeks, P value was 0.05; the difference between preterm birth rate before 34 weeks was statistically significant, P value was 0.05. The preterm birth rate before 34 weeks in the group of multiple pregnancy reduction, TTTS group and TRAP group was significantly higher than that in the group of single chorionic twin-one fetal malformation and sIUGR group. There was no correlation between the number of operation cycles and fetal survival rate, mean gestational weeks, average neonatal weight, abortion rate, preterm delivery rate before 34 weeks, preterm delivery rate before 37 weeks, P value was 0.05, but it was correlated with the intrauterine rate of fetal death, P value was 0.05, with the increase of circulation times, the intrauterine rate of fetal death gradually increased. Fetal reduction is a safe and effective method for the treatment of complicated single-cashmere multiple pregnancy. The indication of operation will affect the premature delivery rate before 34 weeks of fetal retention, and the number of cycles will affect the intrauterine fetal death rate.
