Percutaneous transhepatic catheterization of the portal vein: A combined CT- and fluoroscopy-guided technique.

ABSTRACT

Combined CT- and fluoroscopy-guided transhepatic portal vein catheterization was performed in 44 patients selected for pancreatic islet cell transplantation. The method allowed catheterization with a single puncture attempt in 39 patients. In four patients two attempts and in one patient four attempts were necessary. One minor hematoma of the liver capsule occurred that required no further treatment. Compared with other methods the average number of puncture attempts was reduced.
