FIELD: medicine, cardio-vascular surgery. ^ SUBSTANCE: the trunk of pulmonary artery with a valve should be isolated and dissected together with a muscular fragment by forming it due to capturing muscular part of outlet department of right ventricle. Moreover, it is necessary to cut a muscular part of proximal fragment of pulmonary autograft according to the sizes being correspondent to the defect of aortal root. Then one should implant the pulmonary autograft into aortal position. With muscular fragment one should close the defect of aortal root by applying the sutures through surrounding tissues in area of previously localized commissures by suturing with a blanket suture the autograft's bottom and tissues of aortal foundation from commissure up to commissure. Then, alternately, it is important to reimplant the mouths of coronary arteries and form distal anastomosis between autograft and ascending aortal department, and a biological conduit should be implanted into the position of pulmonary trunk. The innovation in question enables to fulfill adequate substitution of aortal valve with a valuable own valve of pulmonary artery, close the defects of aortal walls, the areas of mitral-aortal contact, fibrous aortal ring with a muscular fragment, reconstruct anatomy and function of aortal root and, also, decrease the number of vitally dangerous complications; moreover, in such patients the intake of anticoagulants is excluded in remote period. ^ EFFECT: higher efficiency. ^ 4 dwg, 1 ex |
