Short- and long-term follow-up results of intima-preserving exoprosthetics of ascending aortic aneurism in 50 patients were studied. The group of control consisted of 54 patients, whom traditional linear prosthetics of ascending aortic aneurism had been performed. Time of artificial circulation and myocardial ischemia was significantly shorter in first group: 60,3±2,6 min and 21±1,7min, respectively. Patients of both groups showed no significant aortic distension postoperatively (34,5±0,7 - 36,6±0,8 mm). Thus, a dosed resection of the ascending aortic aneurism with intima-preserving exoprosthetics proved to be relatively simple and promising technique.
