[Development of a modified bypass system for bridging the anhepatic phase in orthotopic liver transplantation].

The tube-system of the biopump equipment (Bio-medicus, Minnesota/USA) is an essential part of the veno-venous bypass during liver-grafting. In this system turbulences of the blood flow have be avoided because of the unability of heparinization. Any conjunctions parts of the system are areas of potential flow-changes. The number of junctions in the tube-system increase the risk of blood clotting with consecutive intraoperative complications by embolisms. This paper describes a new tube-system with integrated lines for pressure measurements in order to minimize these problems.
