目的 改制微导管同轴法再通提高输卵管阻塞病人的治愈率。方法 将改制微导管插入至输卵管近端入口，应用推注的压力分离粘连。对于阻塞较严重的病人，直接进入导丝再通，在推注及导丝的反复作用下，大部分阻塞的输卵管均可复通。结果 复通率为９２ ．６％ （３６５／３９４） ，２００ 例受治者中有８２ 例怀孕，占４１％ 。结论 改制微导管配合同轴导管行选择性输卵管复通术，输卵管复通率明显高于文献报道，特别为无法治疗的伞端受阻病人，提供了复通及受孕的机会。
Objective To modify the microcatheter coax method to improve the cure rate of tubal occlusion patients. Methods The modified microcatheter was inserted into the proximal tubal entrance, and the pressure was used to separate the adhesions. For more serious obstruction of patients directly into the guide wire recanalization, repeated in the injection and guide wire, most of the obstruction of the fallopian tubes can be recanalization. Resuscitation rate was 92. 6% (365/394), 82 of 200 subjects were pregnant, accounting for 41%. Conclusions The selective microcatheter with coax cannula underwent selective tubal recanalization, tubal recanalization rate was significantly higher than reported in the literature, especially for the treatment of patients with umbrella-side obstruction, provides the opportunity for recanalization and conception.
