ABSTRACT
Objective To investigate the clinical characteristics of tubal stump pregnancy, and to assess the value of interventional embolization in preventing tubal stump pregnancy. Methods Among the patients who were planned to receive preoperative treatment of hydrosalpinx before the performance of in vitro fertilization-embryo transfer (IVF-ET) at authors' hospital, 35 patients had stump of fallopian tube. Of the35 patients, previous surgery of unilateral fallopian tube was present in 28 and previous surgery of bilateral fallopian tubes in 7. The length of tubal stump ranged from 10mm to 45mm, with a mean of 25mm. Interventional embolization with micro-coils was carried out in all patients, after which IVF-ET was performed. The pregnancy rate and ectopic pregnancy rate were calculated. Results Embolization of both fallopian tubes was successfully accomplished in all 35 patients. The IVF-ET pregnancy rate was 48.5％ (17/35), and no tubal stump pregnancy occurred. Conclusion The use of interventional embolization to occlude tubal stump can effectively avoid the occurrence of tubal stump pregnancy.
ABSTRACT
Objective To explore the difference of the impact with different hydrosalpinx pretreatment methods in vitro fertiliza-tion-embryo transfer ﹝ IVF-ET ﹞.Methods 160 patients with routine IVF-ET’s hydrosalpinx were random divided into two groups :the first 80 patients undergoing routine bolt blocking the fallopian tubes for the study group;the other 80 patients with rou-tine salpingectomy as control group patients,after treatment,compare the difference on ovarian function between the two groups.Re-sults In the study group,although these difference,the average number of oocytes,fertilization rate,clinical pregnancy rate and other indicators,were not statistically significant (P>0.05),they were higher than the control group;early abortion rate was no significant difference either (P>0.05),but the tubal pregnancy rate was lower than the control group,and the difference was statis-tically significant (P<0.05).Conclusion Tubal bolt blocking technique is an effective method for hydrosalpinx pretreatment,and partly superior than gynecological surgery for keeping ovarian function and IVF-ET treatment targets.So,it has a broad application prospects in vitro fertilization-embryo transfer.
