Hepatic arterial infusion (HAI) is a medical procedure that delivers chemotherapy directly to the liver.The procedure, mostly used in combination with systemic chemotherapy, plays a role in the treatment of liver metastases in patients with colorectal cancer (CRC). [1]
Using a system of catheters and filters, PHP isolates the liver from the circulatory system and infuses a chemotherapeutic agent directly to the liver via the hepatic artery. The venous effluent from the liver is then filtered outside of the body and the filtered blood is returned into the jugular vein.
TACE of liver tumors derives its beneficial effect by two primary mechanisms. [3] Most tumors within the liver are supplied by the proper hepatic artery, so arterial embolization preferentially interrupts the tumor's blood supply and stalls growth until neovascularization. Secondly, focused administration of chemotherapy allows for delivery of ...
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.

In medicine, vascular access is a means of accessing the bloodstream through the peripheral or central blood vessels in order to obtain blood or deliver medications including chemotherapy. A vascular access procedure involves insertion of a sterile plastic tube called a catheter into a blood vessel. Types of catheters can be either peripherally ...
From E. coli traced to slivered onions on McDonald's Quarter Pounders to mass recalls of frozen waffles due to listeria risk, foodborne illness seems ever-present in the headlines.
By attaching a chemotherapy drug to an antibody, doctors are able to deliver more potent cancer-fighting medicines directly into tumor cells, all while causing fewer side effects.. The ...
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 ...
