1.What is interventional technology? Interventional technology is a minimally invasive treatment technology that has been flourishing in recent years. It involves the use of certain small instruments or apparatus to enter the body cavity, such as the abdominal cavity or blood vessels, to complete certain operations for diagnostic and therapeutic purposes, commonly known as interventional ultrasound technology, interventional endoscopy technology, interventional radiology technology, etc. What we are referring to here is the vascular radiological interventional technique, which is to treat the disease by inserting tiny catheters and guidewires into selected blood vessels under the guidance of X-ray imaging equipment, specifically for the treatment of obstetric and gynecological diseases, the main procedure is uterine artery embolization. 2.What are the obstetrical and gynecological diseases that can be treated by interventional techniques? Interventional techniques were first applied to the treatment of gynecologic malignant tumors in 1950, and after nearly 50 years of research, they are now widely used in various fields of obstetrics and gynecology. It can improve the prognosis of cancer patients by directly injecting anti-cancer drugs into the blood vessels supplying the tumor and embolizing these vessels to improve the ability to kill cancer cells. In benign gynecological diseases, it can be used for uterine fibroids, adenomyosis, tubal pregnancy, cervical pregnancy and refractory functional uterine bleeding. It has become the preferred alternative to hysterectomy for uterine fibroids in developed countries. It can be used in adenomyosis to relieve intractable dysmenorrhea, excessive menstruation and reduce the size of the enlarged uterus; in rare cervical pregnancy, it can cause ischemia, necrosis and resorption or dislodgement of the abnormal growth, avoiding In rare cases of cervical pregnancy, it can cause ischemia, necrosis and resorption or dislodgement of the abnormal growths, avoiding the outcome of hysterectomy due to haemorrhage. In obstetrics, it can be applied to severe postpartum hemorrhage where drug treatment is ineffective, with immediate effect of hemostasis, saving the patient’s life and avoiding the trauma of hysterectomy. 3.What is the difference between interventional treatment and general surgical treatment? The most obvious advantage of interventional treatment for obstetric and gynecological diseases compared with traditional surgery is its minimally invasive nature. Firstly, the incision is very small, only a 2mm (rice grain) puncture is made in the skin of one thigh, which is minimal compared to the incision of about 10-15cm in general open surgery. Secondly, the damage to the body is minimal and the recovery is fast. The interventional procedure takes 30-60 minutes on average, only local anesthesia is needed, no abdomen is opened, no organs are removed, there is almost no bleeding or only a few milliliters during the whole procedure, and you can walk freely one day after the procedure. In addition to minimally invasive, interventional treatment also has the advantage of preserving the female reproductive organs. For severe postpartum hemorrhage, uterine fibroids, adenomyosis and other diseases, the traditional surgical treatment methods, whether transabdominal, transvaginal or laparoscopic, are mainly hysterectomy, while interventional treatment is achieved by injecting drugs into the uterine artery or embolization through cannulae, without removing the uterus, preserving an extremely important organ for women, which is of great significance. 4.Will interventional treatment embolize the blood supply artery of the uterus and cause necrosis or affect the endocrine function of the uterus? No. According to research, although interventional treatment embolizes the uterine artery, it only necroses the tumor cells with high oxygen demand, while normal uterine muscle cells can be supplied with blood through the opening of other small blood vessels without necrosis. Interventional treatment basically has no effect on women’s endocrine function, and normal menstrual cycle can be restored after the operation, and there have been cases of pregnancy and normal delivery again after interventional treatment. 5.What is the development direction of interventional therapy in the field of obstetrics and gynecology? With the popularization of interventional technology, it is expected to become the preferred treatment for benign diseases such as uterine fibroids and adenomyosis in the future, which will not only treat the disease but also preserve the uterus to meet the needs of patients and benefit the majority of women.
