title: New surgical technique for portal venous port system in Swine.
abstract: The need for serial blood sampling and continuous infusion using the portal vein for experimental surgery and pharmacological studies is evident. As suitable animal models are rare, we established a new technique to implant a permanent vascular access device to the portal vein in swine. All operations in study animals (n=8) were technically feasible due to a regularly detected side branch of the portal vein within the inferior pancreatic region; complications did not occur. Mean operation time was 48+/-17 min. This study clearly shows that the portal venous access is feasible and can be achieved safely using the inferior pancreatic vein for a permanent vascular access port system.
