Selective tubal angiography can clearly show the site of tubal obstruction and can avoid false obstruction caused by muscle spasm in the horn of the uterus in conventional hysterosalpingography, with a diagnostic accuracy of 96%. Interventional recanalization is immediately available for patients with tubal obstruction. Both procedures are accompanied by the administration of tubal medication and perfusion. Interventional recanalization of tubal obstruction is the least invasive and least expensive method of recanalization of tubal obstruction. The procedure is intuitive, visualized, safe, less painful, less expensive, with high success rate of recanalization and high conception rate, which is a better treatment for tubal obstruction and has a high reference and guiding meaning for future treatments of choice (such as laparoscopy, IVF, etc.). The operation time is usually only about 20 minutes, and some patients can also choose painless (under anesthesia) surgery. 1.
