The reason why tumors grow rapidly is that there are abnormally thickened and increased arterial blood vessels providing oxygen and nutrients to the tumor. According to this principle, the doctor inserts a thin and flexible tube into the tumor’s blood supply artery from outside the body under X-ray fluoroscopy, and through this special tube, the chemotherapy drug is directly injected into the tumor lesion, so that the tumor tissue receives the impact killing effect of the highly concentrated chemotherapy drug to kill the tumor cells. At the same time, because the drugs are injected directly inside the tumor, while the tissue cells in other normal parts of the body receive less chemotherapy drugs, so it can play the role of improving the efficacy and reducing the systemic toxic side effects of chemotherapy drugs. At the same time, embolic agents can be injected through the catheter to embolize the artery that feeds the tumor and cut off the source of nutrition for tumor growth, so that the tumor is “starved to death”. Embolization is often carried out simultaneously with infusion chemotherapy to achieve the purpose of tumor inactivation. Application range 1.Commonly used in the treatment of benign and malignant tumors. Such as liver cancer, lung cancer, kidney cancer, bladder cancer, benign hepatic hemangioma, uterine fibroids, etc. 2.Hemorrhage caused by malignant tumor (hemoptysis of lung cancer, vomiting blood of stomach cancer, vaginal bleeding of cervical cancer, urinary blood of bladder cancer, ruptured bleeding of liver cancer, etc.), ruptured bleeding of liver and spleen after trauma, gastrointestinal bleeding, postpartum bleeding, etc. Arterial embolization, blocking the bleeding blood vessel with embolic substance, can rapidly stop bleeding. 3.It can cooperate with each other with surgery. For larger tumor, blocking the blood supply of tumor artery by embolization can pave the way for surgical resection to reduce intraoperative bleeding and shrink the tumor, which can help improve the rate of surgical resection.
