Catheterization of the Mesenteric and Portal Vein in Calves

Abstract

Abstract Two types of catheters (double-lumen polyvinyl and silicone rubber) are described that allow dye injection into the anterior mesenteric vein and blood collection from the portal vein of calves. The catheters have been surgically established in 28 calves. The polyvinyl catheters were patent from 1 to 56 days, and the silicone rubber catheters were patent from 10 to 88 days. A unique method, utilizing a sharpened point of bone, was developed for introducing catheters into blood vessels.
