Clinic Comparative Analysis Between Uterine Arterial Embolization And Muscle Injection With Methotrexate Of Treatment Of Unruptured Ectopic Pregnancy

Objective: To explore the clinic value of treatment of uterine arterial embolization with Methotrexate for unruptured ectopic pregnancy .Material and methods: 46 patients diagnosed clinically as ectopic tubal pregnancy were arranged into 2 teams, A team (22patients) was treated by uterine arterial infusion with Methotrexate and embolization with gelfoam, B team (24patients) was treated by muscle injection with Methotrexate. The successful treatment rate, the changement of blood beta-HCG and sonography and the selective salpingography were observed during follow-up. The results were statistical analysed.Results: The successful rate of termination of ectopic pregnancy: A team (22patients) was 100% (22/22) while B team (24patients) was 75%( 18/24); The mean resolution time for reduction of beta-HCG concentratin was 15.27 ± 4.52 days in A team while 18.79±3.99 days in B team; the sonography showed the gestational sac of A team was abstracted in 27.95 ± 4.70 days and that of B team was abstracted in 30.56±5.88 days; the selective salpingography results were same in two teams: A(11/11) and B(8/8).Conclusion: The successful rate of Intra-uterinoarterial Infusion(IUAI) was higher than that of muscle injection with Methotrexate. The bloodbeta-HCG and the sonography were two objective ways of evaluating treatment of ectopic tubal pregnancy. IUAI was effective, reliable for treatment of tubal pregnancy, It would be an important method for termainating tubal pregnancy.
