When injecting, the dosage of injected drugs should be determined according to the patient's age, sex and tumor size. If the operation is improper, it will hinder the normal blood circulation due to sclerosis, so that the surrounding venous blood vessels will expand and the capillaries will expand; If the normal nutrient artery is injured by mistake, it will cause serious ischemia in the nutrient area of the artery, and even cause tissue necrosis and deformity. If the arteries and veins of important organs are damaged, there is a risk of disability. If the tumor is large and the injected drug dose is too small, the drug may enter the heart with the blood flow, which is life-threatening.
Pingyangmycin is often used to treat cavernous hemangioma by injection. Cavernous hemangioma is a congenital venous malformation, and the local venous vessels in the affected area thicken to form a tumor cavity. There is a lot of blood in the tumor cavity, which makes the normal subcutaneous muscle tissue around the tumor and the development of both sides of the body unbalanced. If the lesion belongs to the joint, it will lead to dysfunction. Therefore, it is necessary to be cautious when using Pingyangmycin to treat intra-articular hemangioma.
