There are many factors leading to female infertility, among which tubal obstruction accounts for 20%-40%. Since interventional tubal recanalization has been used in clinical practice, promising results have been achieved in the treatment of tubal obstructive infertility. Patients are selected to have the procedure 4-7 days after menstruation. The day before the procedure, routine leucorrhoea examination is performed, except for mycosis fungoides. The patient was placed in a supine position on the imaging table in a lithotomy position, and the cervix was exposed with a speculum after routine disinfection and the 9F catheter was placed in the cervical canal under the supervision and guidance of the DSA machine. A 5F contrast catheter was fed into the uterine cavity via the 9F catheter, and then a diluted mixture of saline and contrast 11 was used to perform a hysterosalpingogram. After identifying the site of tubal obstruction, the 5F catheter was placed at the horn of the uterus, and a 3F catheter and guidewire were fed along the 5F catheter to unblock the obstructed area. After evacuation, the contrast agent was seen to diffuse more evenly in the abdominal cavity, and then the recanalization fluid (80,000 units of gentamicin, 5 mg of dexamethasone, and 4000 units of α-chymotrypsin) was injected through the 3F catheter. Interventional recanalization of interstitial and narrow tubal obstruction is more effective because these two sites are anatomically closer to the uterine cavity and have a high rate of catheter guidewire placement, recanalization and conception rates. Obstruction of the abdominal and umbilical portions of the fallopian tube is slightly more difficult because these two areas are farther from the uterine cavity. The operator can gently use the guidewire with one hand while pushing the syringe with the other hand to percuss the obstructed area with fluid. The pressure may be increased as much as the patient can tolerate until the contrast agent is diffused through the abdominal cavity. This approach allows recanalization in most patients with jugular and cystic obstruction. After the procedure, the patient rests in bed for 6 to 8 hours, is given a 5-day sedative metronidazole glucose injection, and is prohibited from sexual intercourse for two weeks. In addition, tubal recanalization can be combined with Chinese herbal medicine treatment. Chinese herbal medicine can regulate endocrine and promote ovarian function, thus improving the conception rate. In conclusion, interventional recanalization plays a very important role in the treatment of tubal obstructive infertility. Interventional procedures require gentle and careful handling by the surgeon and focus on comprehensive treatment. For patients with successful recanalization, symptomatic anti-inflammatory treatment should be actively administered to reduce the occurrence of reinfection.
