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.

The cystic artery generally comes from the right hepatic artery. [1] Other variants of right hepatic artery includes: arising directly from the proximal or middle part of common hepatic artery, gastroduodenal artery, superior mesenteric artery, celiac axis, aorta, splenic artery, or left gastric artery instead of arising from proper hepatic ...
Radiation lobectomy: after gaining femoral artery access and advancing a catheter in the right hepatic artery (most often), 90 Y microspheres are infused in a lobar fashion, optimizing tumor and parenchymal coverage. Once the procedure has been completed, the patient is usually sent to the nuclear medicine department where a Bremsstrahlung scan ...
When superficial and deep branches of the cystic artery do not share a common origin, it is defined as a double cystic artery occurring with a frequency of 15%.. The deep branch consistently arises from the right hepatic artery which is generally also the source of origin of the superficial branch, however in some cases it has been found to initiate from the anterior segmental artery, middle ...
The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum, pancreas, and gallbladder. [ citation needed ] It arises from the celiac artery [ 1 ] and has the following branches: [ 2 ]
The cystic artery lies within the hepatobiliary triangle, which is used to locate it during a laparoscopic cholecystectomy. [4] [5] It may also contain an accessory right hepatic artery or an anomalous sectoral bile ducts. As a result, dissection in the triangle of Calot is ill-advised until the lateral-most structures have been cleared and ...
In 1972, surgical ligation of the hepatic artery was first used to treat recurrent hepatic tumors followed by infusion of 5-fluorouracil into the portal vein. Due to the liver's dual blood supply from the hepatic artery and portal vein, interruption of the flow through the hepatic artery was demonstrated to be safe in patients. Tumor ...
A less common, but more serious complication, is hepatic ischemia causing acute liver failure. While healthy livers are predominantly oxygenated by portal blood supply, long-standing portal hypertension results in compensatory hypertrophy of and increased reliance on the hepatic artery for oxygenation.
