Hepatic Arterial Interventions

Hepatic arterial interventions comprise a plethora of procedures that have been curated over the years to treat the majority of hepatocellular pathologies. The contrasting dual blood supply of the liver makes the liver parenchyma remarkably tolerant to ischemia. Since the predominant supply of normal liver parenchyma is from the portal vein (60–70%), the hepatic arterial branches are more expendable. This, in addition to the fact that the majority of pathological entities of the liver receive their supply from the hepatic artery, makes hepatic artery interventions the standard of care for many hepatic pathologies. This chapter describe the various hepatic artery interventions in detail.
