Chemoembolization. Chemoembolization is a two tiered attack on tumor cells. First, chemotherapy drugs are directly injected into the arteries that supply the tumors. Next, the arteries are embolized, or occluded, by particles, this cuts off the blood flow to the tumors.
Anoxia and chemo. With this technique a catheter is advanced through the blood vessels directly to the ones feeding the tumor. Chemotherapy mixed with particles is then given that will block off the blood vessels. This keeps the chemo agent in the tumor helping to kill the tumor and cutting off the bllood supply helps kill the tumor as well. Not all tumor can be treated this way and treatment response can vary.
