3. Treatment
More bilateral pelvic blood cancer, it should also be within the artery on both sides regret chemoembolization, the use of drugs according to histological type. Embolic agent for the chemotherapy drugs commonly used in oil emulsion and gelatin sponge reflect, to try to line superselective catheterization, reduce the related organ and tissue damage, when the catheter tip embolization must be more than superior gluteal artery branch, or buttocks will occur is difficult to intolerable pain.
