目的：探讨选择性输卵管造影与再通术治疗输卵管阻塞的临床价值，验证改进后再通器械的可行性。方法：对６０例１１６条输卵管阻塞引起不孕症患者在透视下，用改进后器械行选择性输卵管造影及再通术。结果：其中近端输卵管再通率９３．８％；总有效率８１．８％；受孕率３１．７％；未发生严重并发症。结论：选择性输卵管造影对病变的诊断效果高于传统的子宫碘油造影，用改进后同轴导管行选择性输卵管造影与再通术方法简便易行，安全可靠，成本低廉
Objective: To explore the clinical value of selective salpingography and recanalization in the treatment of tubal obstruction, and to verify the feasibility of the improved instrumentation. Methods: Sixty cases of 116 tubal obstruction caused by infertility patients under fluoroscopy, with improved equipment selective salpingography and recanalization. Results: The proximal tubal recanalization rate was 93.8%; the total effective rate was 81.8%; the conception rate was 31.7%; no serious complications occurred. Conclusions: Selective fallopian tube angiography is more effective in diagnosing lesions than traditional utero lipiodol. With the improved coaxial catheter, selective salpingography and recanalization are simple, safe and reliable, with low cost
