Interventional tubal revascularization via X-ray is performed by inserting a tubal catheter through the vagina, cervix, uterus and uterine horn into the fallopian tubes under the direct vision of a TV screen under a digital X-ray machine, performing selective imaging of the fallopian tubes, and then inserting a tubal guidewire through the tubal catheter into the fallopian tubes according to the specific site of blockage and the specific situation of the fallopian tubes. The procedure is performed by inserting a tubal guide wire into the fallopian tube through the catheter to reopen and separate the blocked tubes. It is mainly for patients with obstruction in the proximal part of the fallopian tube (interstitial part and isthmus). Advantages of treatment: 1, no surgery, no general anesthesia, painless, safe and effective; the success rate of recanalization is over 90%; 2, little damage, fast recovery, good effect, little disturbance to the body, protecting and preserving normal tissues and organs to the greatest extent; 3, outstanding efficacy: the treatment of interstitial tubal blockage and isthmus blockage directly replaces the original surgical operation, and can preserve the normal tissues.
