Application of interventional embolization of fallopian tube in the prevention of tubal stump pregnancy / 介入放射学杂志

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.
