We all know that tubal intervention can unblock the fallopian tubes, improve the patency of the tubes, increase the patient’s chances of pregnancy, and help reduce the risk of ectopic pregnancy, which is one of the minimally invasive and effective means of treating tubal infertility. What is the clinical application value of tubal embolization? There are more patients who choose in vitro fertilization-embryo transfer (also known as IVF) for various reasons, which is relatively expensive and has a success rate of about 40-50%. Among the many reasons that affect the success rate of IVF-ET, tubal effusion is a very important one. Many studies in recent years have shown that the presence of tubal effusion significantly reduces the clinical pregnancy rate of IVF-ET, even plummeting by nearly half. Appropriate management of hydrosalpinx in IVF Currently, there are four main types of management, namely tubal resection, tubal ostomy, proximal tubal ligation, and aspiration of hydrosalpinx under ultrasound surveillance. Tubal ligation or resection may damage the tubal-ovarian artery arch, resulting in a reduced blood supply to the ipsilateral ovary and affecting the function of the ovary. Tubal ostomy and tubal aspiration reduce the risk of damaging the arteries supplying the ovary, but the possibility of postoperative tubal pregnancy and reoccurrence of hydrocele is extremely high. What is tubal interventional embolization? What are the advantages? Interventional tubal embolization is a mechanical embolization of the proximal fallopian tube using a platinum microspring coil. The microspring coil is delivered through a microcatheter to the interstitial tubules and isthmus to complete the embolization, which was first used primarily as a means of sterilization or permanent contraception. The platinum microspring coils are made of platinum alloy and are used clinically for embolization of tiny vessels. The microspring coils have fibrous villi attached to them, which increase the compatibility with the tubal lining, and aseptic inflammation occurs around the microspring coils after the procedure, which further enhances the effect of embolization. The advantages of interventional tubal embolization compared with several commonly used treatments for hydrosalpinx (such as tubal resection, ligation, stoma and aspiration) are that it does not damage the arterial arch in the tubal lining, does not affect the blood supply and function of the ovaries, is safe, non-invasive, does not require anesthesia and is done on an outpatient basis, and can significantly improve the clinical pregnancy rate of IVF in patients with hydrosalpinx while reducing the risk of ectopic pregnancy. It is a promising new interventional technique.
