[Anatomo-radiological study of venous drainage of the pancreas in the dog].
The anatomic radiological patterns of the venous drainage of the pancreas were studied in 20 dogs, utilizing injection of Schlesinger mass by means of catheter placed on the cranial mesenteric, portal and splenic veins. The drainage of the cranial 2/3 of the right lobe of the pancreas is made by the cranial pancreaticoduodenal vein, while the caudal third is made by the caudal pancreaticoduodenal vein. There are communications between these two veins. The drainage of the angular pancreatic portion in made by venous branches which drain in the gastroduodenal vein. Conversely the drainage of the cranial portion of the left lobe is made by venous branches which drain in the gastroduodenal vein or in the portal vein. The caudal portion is drained by a variable number of veins which are tributary of the splenic vein and a communication between the venous branches from the caudal and cranial portion of this lobe are present in 8 of the 20 dogs studied. The authors emphasize the importance of the careful knowledge of the pancreatic venous anatomy in order to present misinterpretation of the physiological and physiopathological events observed in research which utilizes the dog as the experimental animal.
