Recently, Director Yu Lei of the Interventional Ward of the Cancer Center saw a young female patient with infertility due to tubal obstruction. Ms. Huang, 32 years old, has been infertile for many years due to tubal obstruction and has undergone several tubal lavage treatments without success. Based on her current condition, Director Yu Lei recommended interventional treatment. With the patient’s consent, her tubes were unblocked bilaterally by using COOK-FFC550 tubal reversal series catheter and guidewire under digital subtractor fluoroscopy, and the tubes were seen to be open immediately. The time required was only a few minutes. Currently, tubal obstruction is very common among gynecological diseases and often becomes an important cause of infertility for female patients, causing great distress to patients and families. Tubal obstruction is mainly caused by inflammation spreading upward through the endometrium, which first causes inflammatory changes in the mucosa of the fallopian tubes, degenerative changes in the epithelium of the fallopian tubes or shedding of the epithelium in patches, resulting in adhesion of the mucosa of the fallopian tubes, followed by atresia of the tubal lumen or umbrella. Traditional treatment is mainly tubal lavage or surgery. Although tubal lavage is easy to perform, the accuracy is poor and the results are unsatisfactory. According to the relevant literature, 99.6% of proximal tubal obstruction was opened after interventional recanalization treatment, and the postoperative pregnancy rate was 40.3%. These results suggest that the technique is worthy of promotion and application. In practice, it has been found that in cases of proximal tubal obstruction, the tube can be opened as long as the guidewire can pass through the obstructed segment, whereas in cases of distal obstruction combined with fluid in the umbilicus or heavy adhesions around the tube, opening is relatively difficult and recurrence is easy after surgery. Therefore, it is recommended that appropriate adjuvant treatment should be given after interventional tubal obstruction, such as routine lavage treatment and oral treatment with herbs to activate blood circulation and remove blood stasis within two months after surgery, in order to restore the function of the fallopian tubes as soon as possible and reduce the incidence of tubal reobstruction and ectopic pregnancy.
