chemiombolizáció

Chemiombolizáció, often referred to as chemoembolization, is a minimally invasive procedure used primarily in the treatment of certain types of cancer, particularly liver cancer. It involves delivering chemotherapy drugs directly to a tumor. The procedure begins with a radiologist inserting a thin, flexible tube called a catheter into an artery, usually in the groin. This catheter is then guided through the bloodstream to the blood vessels that supply the tumor. Once the catheter is in place, a contrast dye is injected to visualize the tumor's blood supply. Following this, chemotherapy drugs are infused directly into these vessels. Simultaneously, a blocking agent, such as tiny particles or gel foam, is injected to embolize, or block, the artery. This dual action aims to concentrate the chemotherapy at the tumor site, maximizing its effect while minimizing systemic side effects. The embolization also cuts off the tumor's blood supply, further hindering its growth. Chemiombolizáció is typically performed as an outpatient procedure or with a short hospital stay. It is often used for patients with unresectable tumors, meaning they cannot be surgically removed, or as a bridge to other treatments like transplantation. Potential risks include pain, fever, infection, and damage to surrounding healthy tissues.
