The Bentall-DeBono operation was proposed in 1968. It is the «gold standard" of the aneurysm treatment of the ascending aorta and aortic insufficiency nevertheless this technique is fraught with a number of possible postoperative complications. We have proposed an improved method: two short (10 mm) jaws and «skirt"« formed from the distal portion of the prosthesis were sewed to valved conduit. 19 operations were done by the proposed method in all. The control group included 73 patients who had operation according to the standard technique. Duration of extracorporeal circulation, myocardial ischemia, blood loss were the following: 145.4±54.4 and 117.4±40.9 min; 106.4±30.2 and 77.5±22.5 min; 473±355 and 1853±940 ml respectively. The mortality rate was 5.2% and 10.9% respectively. Our experience shows the technical simplicity of the procedure and satisfactory postoperative results.
