Clinical use of Jostra Rota Flow centrifugal pump: the first case report in Japan.

: A Jostra Rota Flow centrifugal blood pump was clinically applied for a cardiopulmonary bypass (CPB) of an ascending aortic replacement for type A aortic dissection. The patient was a 68-year-old female with Stanford type A, DeBakey type II thrombosed aortic dissection complicated by cardiac tamponade and moderate aortic regurgitation. The surgery was carried out on December 22, 1998. The air inside the pump was easily and quickly removed, and its mode of control was excellent. The pump flow during the operation was maintained at about 2.2 l/m2. Total CPB time was 179 minutes. Macroscopically and microscopically, there were no thrombi inside the pump, after usage. The postoperative course was uneventful. The clinical use of this pump was the first case in Japan. This pump is excellent in the ease by which it's controlled due to its compact size and low weight. Furthermore, the Rota Flow console can be fully integrated in the HL-20 heart-lung machine, and these systems have pulsatile flow mode possibility. This pump is suitable not only for the main pump of CPB but also circulatory support.
