Resumo
Estudou-se o comportamento do sistema portal hepático em 30 patos domésticos, adultos, machos e fêmeas. O sistema apresenta-se constituído por duas veias portais hepáticas: direita e esquerda. A veia portal hepática esquerda é formada por veias gástricas esquerdas (em número de 1 a 2), veias da margem ventral do ventrículo, veia pilórica e veia proventricular caudal. A veia portal hepática direita é formada pela veia mesentérica caudal, veia mesentérica cranial, veia proventrículo-esplênica e veia gastropancreaticoduodenal. A veia mesentérica caudal recebe tributárias do mesorreto, cloaca e junção ileocecocólica. A veia mesentérica cranial recebe tributárias jejunais (em número de 12 a 21) e se anastomosa com a veia mesentérica caudal, formando a veia mesentérica comum. A veia pancreaticoduodenal recebe duas veias gástricas direitas, constituindo assim a veia gastropancreaticoduodenal. A veia proventrículo-esplênica é formada pelas veias proventriculares dorsal e direita e pelas veias esplênicas.
In this research a study on the course of the portal hepatic system in 30 adult domestic ducks, male and female was performed. The portal venous system consists of two portal hepatic veins: right and left. The left portal hepatic vein is formed by left gastric veins (in a number varying from 1 to 2), veins from the ventral margin of the gizzard, piloric vein and caudal proventricular vein. The right portal hepatic vein is formed by the caudal mesenteric vein, cranial mesenteric vein, proventricular-spleenic vein and gastro-pancreatic-duodenal vein. The mesenteric caudal vein takes in tributaries from the mesorectum, cloaca and ileo-cecum-colic junction. The cranial mesenteric vein takes in jejunal tributaries (in number varying from 12 to 21) and forms anastomosys with the caudal mesenteric vein, which results in the common mesenteric vein. The pancreatic-duodenal vein receives two right gastric veins, this way forming the gastro-pancreatic-duodenal vein. The proventricular-spleenic vein is formed by the dorsal and right proventricular vein and by the spleenic veins.
