. We have introduced and evaluated several modifications of the conventional venovenous bypass (VVBP) in 29 adult patients under‐going liver transplantation (OLT). A percutaneous technique for insertion of a jugular venous return cannula and a femoral vein cannula was applied. The inferior mesenteric vein (IMV) was used for splanchnic decompression, which facilitated dissection of the recipient liver and allowed portal anastomosis to be performed without disconnecting the portal bypass. A heat exchanger was introduced into the bypass circuit to prevent heat loss. The percutaneous technique prevented complications related to dissection in the axilla and groin. Hemodynamic characteristics corresponded to those found using the traditional technique. Complications related to the VVBP were seen in only one patient in whom the femoral cathe‐ter was accidentally introduced into the femoral artery. We conclude that percutaneous cannulas, use of the IMV for splanchnic ecompression and the introduction of a heat exchanger offer significant benefits and that they are safe and reliable.
