Abstract

The present study was design to investigate the hepatic arteries branches and your intraparenchymal distribution in agoutis. Were studied ten agouti's livers, female and male from our colony (Núcleo de Estudos de Preservação de Animais Silvestres do Centro de Ciências Agrárias da Universidade Federal do Piauí - FUFPI/IBAMA 02/99). After injection with colored latex Neoprene 650 (DuPont do Brasil, Chemistry Industries), through the hepatic artery, eight livers were dissected through the visceral faces. The samples were fixed in 10% aqueous formaldehyde solution and after a minimum period of 48 hours. Two organs were injected with colored vinil acetate, following procedures of acid chloride corrosion in order to obtained vascular casts. The study shows that the agouti's hepatic arteries bifurcate into two principals branches, right and left (100%). In general, the right branches usually (80%) gave origin vessels that are responsible for the right medial, right lateral and caudate lobes's vascularization. The left branches normally (80%) give origin vessels that are responsible for the left medial, left lateral, quadrate lobes's vascularization, also to the caudate lobos (50%) and right lateral (20%). In this way, the vascular distribution of the hepatic artery is related to the organ's lobos; where the right and left branches have intraparenchymal distribution into the liver's lobos. This study gave support to the anatomic-surgery artery segmentation.
