METHOD FOR PROXIMAL ANASTOMOSIS APPLICATION IN CASE OF SUPRA-CORONARY PROSTHETICS OF ASCENDING AORTA Russian patent published in 2017 - IPC A61B17/00 A61B17/11 

FIELD: medicine.

SUBSTANCE: ends of the corrugated synthetic tube and the proximal end of the aorta are connected after its transverse intersection above the sinotubular junction level. Beforehand, the tube end is turned out all around the perimeter. Through the inverted end of the tube, three U-shaped sutures are drawn. The threads of each suture are drawn from the space between the main tube and the outwardly turned portion thereof, 1-2 mm away from the bending line. The anastomosing end of the tube is placed inside the aorta root. The threads of the superimposed sutures are directed through the anastomosed aortic department. A 4-6 mm wide strip is cut from Teflon felt; the strip length corresponds to the length of the anastomosis circumference. The strip is located outside the aorta along the anastomosis circumference. Threads of superimposed seams are conducted through the strip. The inverted end of the tube and strip are fixed by tying the imposed suture threads to the inner and outer surfaces of the aortic wall, respectively. An anastomosis line is formed with a continuous mattress suture. At that, the edge of the inverted tube section, the edge of the aorta and the felt strip are connected. Then the final sealing of the anastomosis is carried out, applying a continuous twisted suture to the indicated sections.

EFFECT: method allows to increase the strength and tightness of the proximal anastomosis at supracoronary aortic prosthetics, simplify the technique of its application, reduce intraoperative blood loss due to hemorrhages along the suture line, prevent joint eruption due to double anastomosis strengthening from the inside - by the inverted part of the prosthesis and externally - by the Teflon strip.
