Case ReportsOff-pump total arterial bypass grafting using bilateral mammary, gastroepiploic, and radial artery.
The indication for off-pump coronary artery bypass grafting (CABG) have been expanded as development of the off-pump device has progressed. We present a case of four-vessel revascularization with total arterial graft under a beating heart. All conduits were in situ or composite, and bypass was performed with aorta non-touch technique. Off-pump bypass using in situ quadruple arterial conduits may contribute to a reduction of incidence of perioperative strokes and reduction of the postoperative cardiac events.

Two types small and efficient ECMO oxygenators were developed utilizing the most up to date hollow fiber technology. Newly silicone hollow fibers possess sufficient mechanical strength while maintaining ultra thin walls of 50 micro meter. Two types of oxygenators were made with this fiber. ⋯ Additionally, comparative hemolysis tests were preformed with this new oxygenator and the Kolbow. The NIH value was 0.006 (g/100 L) for the type 1 oxygenator and 0.01 (g/100 L) for the Kolbow oxygenator. These results suggested that this ECMO oxygenator had sufficient gas exchange performance in spite of being smaller and induced minimal blood damage.
