Hepatic artery embolization, also known as trans-arterial embolization (TAE), is one of the several therapeutic methods to treat primary liver tumors or metastases to the liver. The embolization therapy can reduce the size of the tumor, and decrease the tumor's impact such its hormone production, effectively decreasing symptoms.
Hence, arterial treatment targets the tumor while normal liver is relatively spared. Embolization induces ischemic necrosis of tumor causing a failure of the transmembrane pump, resulting in a greater absorption of cytotoxic agents by the tumor cells. Tissue concentration of agents within the tumor is greater than 40 times that of the ...
Transarterial bland embolization (TAE, also known as HAE) is a catheter-based tumor treatment of the liver.In this procedure, embolizing agents (e.g., polyvinyl alcohol, gelfoam, acrylic copolymer gelatin particles, embospheres) can be delivered through the tumor's feeding artery in order to completely occlude the tumor's blood supply.
A new treatment for liver cancer which isolates the organ and “bathes” it in chemotherapy has been found to be effective in almost 90% of patients. The procedure being pioneered in the UK at ...
Transarterial embolization (TAE)/bland embolization: Injection of embolic material (microparticles, alcohol, glue) through a catheter into the arteries feeding a tumor in order to completely occlude the tumor's blood supply and cause cell death. The most common indication is for treatment of unresectable liver cancer (hepatocellular carcinoma ...
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
Portal vein embolization (PVE) is a preoperative procedure performed in interventional radiology to initiate hypertrophy of the anticipated future liver remnant a couple weeks prior to a major liver resection procedure. The procedure involves injecting the right or left portal vein with embolic material to occlude portal blood flow.
Following embolization of the yttrium-90 glass microspheres in tumorous liver tissue, the beta radiation emitted provides a therapeutic effect. The microspheres are delivered into the liver tumor through a catheter placed into the hepatic artery that supplies blood to the tumor. This is usually performed in a hospital's radiology suite and ...
