With the improvement of medical technology, more and more diseases can be treated with minimally invasive interventions to obtain better results. In gynecological diseases, there are many such diseases that require surgical removal of the uterus to cure, but now interventional treatment can achieve the same effect and preserve the uterus, however, because interventional treatment is relatively new to the general public compared to medical surgery, many people are not aware of this method. Now we will briefly introduce it here. Uterine fibroids are the most common benign gynecological tumors, known as the “first tumor of women”, and are most common in women between the ages of 30 and 50 during their reproductive years. The traditional treatment is hysterectomy. Instead of removing the uterus, the uterine artery embolization method of interventional therapy can be used to remove the fibroid while preserving the uterus, especially for young or fertile women. It requires only a rice-sized puncture in the femoral artery and a catheter to the uterine artery, which is then blocked with drugs. After the embolization of the uterine artery, the fibroid will be deprived of blood and oxygen, then necrosis, volume shrinkage and the body slowly absorbed or just fall off. In contrast, normal uterine tissue is able to tolerate ischemia and hypoxia, and because the uterus has abundant collateral circulation, a new blood supply can be established in a relatively short time, thus uterine necrosis does not occur. As a result, the fibroids are treated and the uterus is preserved, with a rice-sized wound that does not even need to be sterilized after surgery, at most a band-aid. 2, adenomyosis Uterine adenomyosis may be less heard of, it refers to the endometrial glands and interstitial invasion of the myometrium to form a diffuse or limited lesion. In layman’s terms, this means that the endometrium has grown in the wrong place and has run into the myometrium. Adenomyosis usually occurs in menstruating women in their 30s and 50s, but occasionally it can be seen in young, infertile women. It has the typical symptom of secondary dysmenorrhea, which is usually severe and affects rest and work, often requiring strong painkillers to relieve it. If the lesion is severe, the pain can occur even during menstruation and is often described by patients as “pain worse than death”. In the past, adenomyosis was difficult to treat because of the ineffectiveness of medication and surgical treatment, which usually required removal of the uterus to cure the disease. Now it is possible to solve the problem without removing the uterus, similar to the surgery for fibroids, with an uncomplicated “uterine artery embolization”. Most of the fibroids are vascular diseases and the growth of the lesions requires blood supply and stimulation of estrogen, progesterone and other growth factors in the blood. The use of uterine artery embolization can block its blood vessels with drugs for the purpose of starving it out. Because the myometrium is resistant to hypoxia, while the endometrium that grows in the wrong place is not, it can achieve a better treatment effect. 3, postpartum hemorrhage I believe that many women who have given birth know that, for women, postpartum hemorrhage after childbirth is a threshold, if there is no timely treatment is likely to lose their lives. The surgical removal of the uterus is often used, but it is difficult for the mother and her family to make a decision immediately because of the series of consequences after the removal of the uterus, and therefore the condition is often delayed. Because this is an emergency situation, unlike general diseases, you can choose to go to some large hospitals, if the hospital does not have an interventional department, the only way to use hysterectomy. As long as the hospital has an interventional department, generally when encountering this situation, the interventional doctor will be asked to see if uterine artery embolization can be performed to stop the bleeding. Scar pregnancy, placenta praevia and placenta implantation Scar pregnancy: it is a woman who has a history of cesarean delivery and the gestational sac lodges in the original scar of the uterus during her second pregnancy, which often leads to heavy vaginal bleeding and late uterine rupture, which is as dangerous as ectopic pregnancy and is one of the biggest headaches for obstetricians. Anterior placenta: The placenta is implanted in the lower part of the uterus or over the inner cervical opening, before the fetal previa. It is in the middle to late pregnancy and can present with mild to severe vaginal bleeding; it is a serious complication of pregnancy and can endanger the life of mother and child if not treated properly. Placental implantation: It is the penetration of placental villi into the myometrium of the uterine wall and occurs in early pregnancy when the placenta is implanted rather than in late pregnancy. It is one of the serious complications of obstetrics and is very likely to cause severe postpartum hemorrhage. These disorders are listed together because they all have a similar presentation: the potential to cause severe hemorrhage. All of these diseases can be treated with interventional therapy, i.e. uterine artery embolization, to block the blood vessels before further treatment, effectively avoiding hemorrhage without the fear of being faced with the painful choice of whether to remove the uterus or not.
