Tubal effusion has a great impact on IVF success rate. Research results show that the presence of tubal effusion decreases the IVF pregnancy rate by at least 50% and increases the spontaneous abortion rate by 2 times. In order to improve the pregnancy rate of IVF, the preoperative treatment of hydrocele has become the key. There are four methods: laparoscopic salpingo-oophorectomy, ligation, open window or ultrasound aspiration. The latter two methods are prone to recurrence after tubal effusion and have a higher likelihood of tubal pregnancy. (a) Advantages of interventional embolization for hydrosalpinx 1. avoiding the risk of surgery and anesthesia; 2. avoiding the impact on ovarian blood supply; 3. preventing the recurrence of tubal pregnancy and hydrosalpinx, and safe operation, minimal patient pain and short postoperative recovery period. (B) Indications for tubal interventional embolization 1. 1, hydrosalpinx on one or both tubes confirmed by imaging or ultrasound; 2, patients eligible for IVF; 3, other patients requiring tubal embolization. (3) Contraindications for tubal interventional embolization 1.Acute or subacute inflammation of internal and external genital organs or chronic inflammation; 2.Serious systemic diseases that cannot tolerate the procedure; 3.Pregnancy and menstruation; 4.Postpartum, abortion, or within 6 weeks after curettage.
