Ultrasound-guided catheterization of the portal vein in 11 cows using the Seldinger technique.
Catheterization of the portal vein using the Seldinger technique [Acta Radiol. (1958) 38, 368] was performed in 11 cows. Ultrasound-guided percutaneous portocentesis, using a 25-cm, 14-gauge steel cannula, was performed from the 10th, 11th or 12th intercostal space on the right side. A stylet was placed through the cannula, which was then removed, and a polyurethane balloon-tipped catheter was advanced over the stylet into the portal vein and sutured to the skin (Seldinger, 1952). ⋯ Generally, the severity of the lesions was mild. The results of this study demonstrated that ultrasound-guided percutaneous catheterization of the portal vein, using the Seldinger technique, is possible in cows. The catheter may be left in place for collection of blood samples for up to 15 days.
