输卵管梗阻包括了2种类型，一种为输卵管纤维化、粘连造成的真性闭塞，另一种为输卵管腔内黏液栓、炎症造成的输卵管功能性梗阻。文章讨论的可介入疏通的输卵管疾病实为后者，而真性闭塞一般较难疏通，往往在治疗无果行辅助生殖技术前可酌情行介入栓塞处理。输卵管梗阻的主要原因是黏液、碎屑阻塞管腔，疏通成功率高，但针对输卵管中远段阻塞、输卵管既往损伤史、一些特殊的输卵管炎性病变时，介入治疗的适应证尚不明确。文章将探讨输卵管梗阻介入治疗中的普遍规则及个体化经验，以期使患者收益最大化，增加其自然受孕概率。

Tubal obstruction includes two types，one is true occlusion caused by tubal fibrosis and adhesions，and the other is tubal functional obstruction caused by mucus plugs and inflammation in the tubal lumen. The tubal diseases discussed in this article that are amenable to interventional evacuation are actually the latter，while true occlusions are generally more difficult to evacuate and are often treated with interventional embolisation prior to assisted reproduction after unsuccessful treatment. The main cause of tubal obstruction is obstruction of the lumen by mucus and debris，and the success rate of unblocking is high. However，the indications for interventional therapy are unclear in the cases of middle and distant tubal obstruction，the cases with history of previous tubal injuries，and those with specific tubal inflammatory lesions，and this article discusses the general rules and individualized experience in the interventional treatment of tubal infarction with a view to maximize the benefits for the patient and increase the chances of natural conception.
