OVERLAPING METHOD OF RAST ANASTOMOSIS IN PROSTHETIC AORTA (OPTIONS) Russian patent published in 2018 - IPC A61B17/00 A61B17/11 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, specifically to cardiovascular surgery. In the presence of stratified or severely thinned less than 2 mm of the aortic wall, an anastomosis is formed by using a felt strip. From the outside of the anastomosed aortic section, a felt strip is circularly laid. A continuous suture seam from the back wall of the anastomosis is applied, continuing it on the side and front walls. When forming the seam along the entire perimeter of the anastomosis, each stitch of the seam is performed as follows: a puncture of the prosthesis from the inside out, retreating from its edge by 1–2 mm; further, a puncture of the aortic wall from the inside out to the opposite of the graft out of the prosthesis is performed, retreating from its edge by 10–15 mm, and after puncturing from the outside of the aorta pierce the felt strip simultaneously is needled; after which the prosthesis is needled from the outside to the inside, retreating from its edge 10–15 mm and displacing the point of thrust along the line of anastomosis to the distance corresponding to the next stitch of the seam. After each imposed stitch, it is tightened and the part of the prosthesis is immersed in the aortic lumen. In the absence of thinning of the aortic wall, there is no need to use capping when applying seams. A continuous suture seam from the back wall of the anastomosis is applied, continuing it on the side and front walls. When forming the seam along the entire perimeter of the anastomosis, each stitch of the seam is performed in the following way: the prosthesis is pinched from the inside to the outside, retreating from its edge by 1–2 mm; further, a puncture of the aortic wall from the inside out to the opposite of the graft out of the prosthesis is performed, retreating from its edge by 10–15 mm; then the denture is needled from the outside inwards, away from its edge for 10–15 mm and shifting the point of injection through the anastomosis line to the distance corresponding to the next stitch of the seam. After each imposed stitch, it is tightened and the part of the prosthesis is immersed in the aortic lumen.

EFFECT: group of inventions allows to form a tight and stable to deformations distal anastomosis with aortic prosthetics.
