Experimental study on methods of hepatic artery occlusion and its application at different levels

Abstract

Proximal and peripheral hepatic artery occlusion (HAO) have been experimentally performed in 18 dogs, and biochemical and pathological changes were observed. Our results show that the damage done to normal hepatic tissue of the dog by peripheral HAO is far greater than that by proximal HAO. Feasibility and rationality of peripheral HAO are discussed. Meanwhile, we attempt to define the concept of peripheral HAO and permanent HAO. A new embolic is suggested and tried in this study.
