It is the most common benign tumor in women of reproductive age, and is the “first tumor” in gynecology. Patients with uterine fibroids may experience frequent menstruation, excessive menstruation and prolonged menstruation, which may lead to secondary anemia and decrease in physical fitness. It can lead to infertility or miscarriage, and the literature reports that 20-40% of patients with leiomyosarcoma are infertile. Some patients may experience dysmenorrhea, and some patients may experience lumbosacral pain. It can cause obstructive labor during pregnancy and delivery, causing much pain and danger to mother and child. If you know you have fibroids, you need further treatment if conservative treatment has not worked and you have a tendency to increase in size. If you are older, have significant symptoms, and do not wish to preserve your uterus, you may opt for surgical removal. If you are interested in preserving your uterus and fertility and are afraid of surgical treatment, you can choose the minimally invasive treatment method – uterine artery embolization. 1.What is uterine artery embolization? Uterine artery embolization refers to selective insertion of a catheter into the uterine artery under the guidance of medical imaging equipment to embolize the blood supplying artery of the fibroid, which causes ischemia and necrosis of the fibroid, resulting in the shrinkage and disappearance of the fibroid, thus achieving the purpose of treatment. After uterine artery embolization, both the uterus and the myoma are in a state of acute ischemia, but later they have distinctly different pathological changes. The myoma tissue is necrotic due to the persistent ischemia, first in the superficial layer where it is actively growing, and then gradually inwards, and finally the myoma tissue is completely necrotic and is absorbed by the body and expelled. The opposite is true for the normal tissue of the uterus. The distal vessels of the uterus are rich in traffic arteries, which are not open under normal conditions, and after embolization these traffic arteries open and can obtain a small amount of blood through the ovarian artery and the internal pubic artery, which is sufficient to maintain the uterus. By these two opposite pathological changes, the purpose of treating the myoma and preserving the uterus at the same time is achieved. Uterine artery embolization is suitable for all types and sizes of fibroids (including huge and multiple fibroids), and it is still effective for fibroids that recur after surgery and for which other methods of treatment are ineffective, and is the treatment of choice for patients who require preservation of the uterus and reproductive function. It has the following advantages: (1) the use of arterial cannula for drug injection, which is less traumatic; (2) avoiding the removal of the uterus, preserving the reproductive function and secondary female sex characteristics; (3) less painful, less side effects, faster recovery and shorter hospital stay, usually only 5-6 days; (4) simpler and cheaper than traditional surgical treatment, without blood transfusion; (5) significantly higher pregnancy rate after treatment; (6) a series of symptoms after treatment. (6) A series of symptoms significantly improve or disappear after treatment. In particular, apart from treating uterine fibroids and adenomyosis, radio-interventional therapy is also a good treatment for other gynecological diseases, such as infusion chemotherapy with embolization for gynecological malignancies, interventional tubal revascularization for infertility, interventional ectopic pregnancy (ectopic pregnancy) inactivation treatment, embolization of uterine artery for a variety of obstetric and gynecological bleeding such as postpartum bleeding, gynecological tumor bleeding, traumatic bleeding, etc. bleeding, etc.
