Obstetrics and gynecology interventional treatment belongs to the category of minimally invasive medicine, and minimally invasive technology is a major trend in the development of future clinical medical procedures. Obstetrics and gynecology interventional treatment is a “non-surgical” method of diagnosing and treating related diseases through percutaneous puncture techniques under the guidance of imaging methods, such as interventional recanalization, drug perfusion, vascular embolization or puncture biopsy, and vasodilation and angioplasty. Interventional therapy has opened up new treatment pathways, especially for conditions that were previously considered incurable or difficult to treat, and is simple, safe, less invasive, less comorbid, and more effective, which is welcomed by patients. Interventional treatment gives obstetrics and gynecology patients the opportunity to choose the treatment, and under certain conditions can avoid the pain of open abdomen or hysterectomy, improve the effectiveness of disease treatment, and truly appreciate the minimally invasive advantages of interventional treatment. Main indications: i. Interventional recanalization treatment for tubal obstruction and selective tubal angiography (FTR + SSG), which gives drug infusion while unblocking the fallopian tubes, is the treatment of choice for proximal tubal obstruction. The procedure is performed on an outpatient basis and is basically non-invasive. It takes about 20 minutes to perform and you can go home after a short rest after the procedure. Interventional embolization of hydrosalpinx: Before IVF, hydrosalpinx needs to be treated by embolization of the proximal part of the isthmus with a microspring coil, which can be done on an outpatient basis. Embolization significantly reduces miscarriage due to reflux of the fluid and improves the success rate, and significantly reduces the risk of ectopic pregnancy. In the past, tubectomy or tuboplasty and ostomy were performed laparoscopically or openly, which required hospitalization and was relatively expensive. Uterine fibroids and adenomyosis (tumors): uterine artery embolization is effective in relieving dysmenorrhea caused by adenomyosis and improving the symptoms of anemia caused by fibroids. IV. Obstetrical and gynecological emergency bleeding and vascular malformation: uterine artery embolization as an alternative treatment to hysterectomy and drug therapy has the advantages of short treatment time, significant efficacy, no need to remove the uterus, no scar on the abdomen, less pain and easy tolerance by patients. V. Cervical/angle pregnancy, incisional pregnancy, placenta placement: uterine artery embolization is applied to the treatment of this disease and combined with postoperative uterine clearance, preserving the uterus and reproductive function while significantly reducing the risk of hemorrhage and shortening the hospital stay, with the advantages of simplicity, minimally invasive, less bleeding and faster recovery. Interventional treatment of gynecological malignant tumors: cervical cancer, endometrial cancer, choriocarcinoma, malignant staphyloma, ovarian cancer, vaginal cancer, vulvar cancer and other preoperative and postoperative adjuvant chemotherapy, etc.
