Preoperative PVE is a very well tolerated procedure with extremely low mortality rates (0.1 percent) and technical failure rates (0.4 percent). [3] Complication rates from the procedure are low as well (2–3 percent) and include portal vein thrombosis, liver infarction, necrosis, infection, pneumothorax, and other risks as listed above. [3]
1990 – Radiofrequency ablation (RFA) technique for liver tumors. 1990s – Treatment of bone and kidney tumors by embolization. 1990s – RFA for soft tissue tumors, i.e., bone, breast, kidney, lung and liver cancer. 1997 – Intra-arterial delivery of tumor-killing viruses and gene therapy vectors to the liver.
The several types of hepatic artery treatments are based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70-80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the hepatic artery effectively blocked.

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.
Thus, in people with advanced liver disease the shunting of portal blood away from hepatocytes is usually well tolerated. However, in some cases suddenly shunting portal blood flow away from the liver may result in acute liver failure secondary to hepatic ischemia. [6] Acute hepatic dysfunction after TIPS may require emergent closure of the shunt.
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 ...
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [ 1 ] [ 2 ] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [ 3 ]
The LiMAx test is an innovative enzymatic liver function test. 13 C-methacetin, a selective metabolite of the liver specific cytochrome P450 1A2 is administered intravenously. Via the bloodstream the drug is transported to the liver and immediately metabolized to paracetamol and ultimately to 13 CO 2 (Fig. 1), which is in turn transported via ...
