The incidence of malignant tumors of uterus (endometrial cancer, cervical cancer, etc.) is increasing year by year, which seriously threatens women’s life and health. In the past, the treatment of gynecological malignant tumors mostly adopted comprehensive treatment methods, such as surgery, radiotherapy and chemotherapy. Due to the advantages of interventional therapy such as less damage, high efficacy and less side effects, it is increasingly applied in the treatment of uterine malignant tumors. In the early stage, bilateral internal iliac artery infusion chemotherapy was used for one-time infusion at regular doses, and later low-dose continuous arterial infusion chemotherapy was used. In recent years, in order to further improve the efficacy, uterine artery embolization was added along with arterial perfusion chemotherapy. The blood supply of uterine malignancy is mainly supplied by the uterine artery, a branch of the internal iliac artery. Arterial chemotherapy chemotherapy perfusion can make the drug concentration in pelvic tissues 10~100 times higher than that of intravenous administration, while the local drug concentration within a certain range increases by 1 times and the effect of killing tumor cells is enhanced by 10 times. Uterine artery chemotherapy infusion can increase the concentration of chemotherapy drugs in the local tissues of cancer cell tumors, improve the efficacy, and also reduce the toxic side effects of chemotherapy drugs on the whole body. At present, the most commonly used embolic agents for uterine artery embolization are iodinated oil, PVA pellets and gelatin sponge, among which gelatin sponge is the safest and most effective. The branch vessels below the level of the main uterine artery are embolized with gelatin sponge pellets, and then the main uterine artery is embolized with gelatin sponge strips to make embolization more complete. On the one hand, the gelatin sponge can adsorb part of the drugs to embolize the blood vessels, and the sponge continues to play the role of drugs in the blood vessels because of adsorbing part of the drugs, on the other hand, because of embolizing the bilateral uterine arteries or tumor blood supply arteries, the blood supply to the tumor area is reduced, and the blood transport of the cancer is blocked, resulting in ischemia and hypoxia of the cancer cells and degeneration and necrosis, and the mass shrinks or disappears, which is more conducive to surgical resection, and also enables some advanced cancer patients to have another chance of surgery. It also enables some advanced cancer patients to have another chance of surgery, and can achieve the purpose of hemostasis by embolizing blood vessels.
