双侧输卵管结扎术后异位妊娠35例分析

ANALYSIS OF 35 CASES IN ECTOPIC PREGNANCYAFTER BILATERAL LIGATION OF OVIDUCT

回顾性分析１９９２～１９９７年间我院诊治的３５例双侧输卵管结扎术后异位妊娠的临床资料，探讨其发病原因，误诊情况与ＭＲＩ在诊断中的作用，及新的治疗方法。提出排卵期结扎、单纯结扎、输卵管远段部位结扎等为结扎术后异位妊娠的医源性因素；ＭＲＩ能够区分不同时期的血液成份，能很好地显示异位妊娠的形态学特点；非异位妊娠侧输卵管应同时结扎加固或切除，以防止再次异位妊娠发生；米非司酮治疗异位妊娠用药剂量大。

It was reviewed in 35 cases in ectopic pregnancy after bilateral ligation of oviduct from 1992 to 1997 in our hospital.We explored its cause,misdiagnosis,MRI usefulness,and new theraputic methods.The medical causes contained ligation in ovulatory period,simple ligation,ligation in the distal part of oviduct.MRI could display blood elements in different period,so it visualized the pattern of ectopic pregnancy well.In order to avoid ectopic pregnancy again,that should be removed or ligation consolidation for oviduct in nonectopic pregency side at the same time.Because the dosage of mifepristone was great in the therapy of ectopic pregnancy,it should be under guard closely.
