Tubal obstruction is a common cause of female infertility, accounting for about 30% of female infertility. The treatment of tubal infertility is a difficult problem of infertility. With the continuous development of interventional radiology technology, selective tubal imaging and recanalization has become an effective method of clinical treatment of tubal obstruction infertility. Its principle is: through the uterine cavity imaging and tubal selective imaging clearly diagnosed tubal obstruction, and then use special tubal recanalization instruments (coaxial catheter, guide wire system) using high-pressure liquids, mechanical micro-force and other means to make the obstructed section reopen, after the operation with the uterine cavity irrigation, anti-inflammatory and other auxiliary treatments to maintain the usual, and then the rate of pregnancy can reach about 60%. Interventional tubal recanalization brings new hope to infertility patients with its minimally invasive, safe, efficient and low cost.
