How is percutaneous alcohol injection done and how does it work? In this technique, pure alcohol is injected into liver cancers to kill the cancer cells. The alcohol is injected through the skin (percutaneously) into the tumor using a very thin needle with the help of ultrasound or CT visual guidance. Alcohol induces tumor destruction by drawing water out of tumor cells (dehydrating them) and thereby altering (denaturing) the structure of cellular proteins.It may take up to five or six sessions of injections to completely destroy the cancer. Which patients are treated with percutaneous alcohol injection? The ideal patient for alcohol injection has fewer than three Hepatocellular Carcinoma (HCC) tumors, each of which is:
Additionally, patients with HCC undergoing alcohol injection should have no signs of chronic liver failure, such as ascites or jaundice. (Patients with liver failure would not be able to tolerate the alcohol injections.) What are the side effects of percutaneous alcohol injection? The most common side effect of alcohol injection is leakage of alcohol onto the surface of the liver and into the abdominal cavity, thereby causing pain and fever. It is important that the location of the tumor relative to the adjacent blood vessels and bile ducts is clearly identified. The reason for needing to locate these structures is to avoid injuring them during the procedure and causing bleeding, bile duct inflammation, or bile leakage.
