METHOD OF VASCULAR ANASTOMOSIS APPLICATION Russian patent published in 2020 - IPC A61B17/00 A61B17/11 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to vascular surgery. Vascular end-to-side anastomosis is applied between an autovenous graft and an artery by means of a viscous vascular suture with atraumatic non-absorbable monofilament with two needles at the ends with cutting the flap from the artery wall in the anastomosis beginning area. Autovenous transplant is cut out with a longitudinal flap whose length is equal to the length of the circumference of the cross-section of the autologous transplant, and the width is equal to its diameter. On the surface of the autovenous graft, diametrically opposite to the flap, a longitudinal incision is made, length of which is equal to length of circumference of autovenous graft cross-section when dividing the edges of the incision. Cut has the rhomb shape. Long incision is made on an artery and lengthwise is equal to a longitudinal incision on the autovenous transplant. Additionally, a transverse incision is made on the arteries, the length of which is equal to ½ of the circumference of the cross-section of the autovenous transplant, which is located T-shaped relative to the longitudinal incision. Hole matching the longitudinal flap on the autovenous transplant is additionally cut out on the arteries; the arterial opening looks like a rhomb when dividing the edges of the incision. Vascular anastomosis is formed, an autovenous transplant is sutured to the artery so that the anastomosis starts in the region of longitudinal incisions, and the end - in the region of the rhombus nearest to the operator to the artery.

EFFECT: method enables eliminating the risk of anastomotic narrowing, reducing the time of anastomosis, reducing the risk of shun thrombosis or arteriovenous fistula and achieving good clinical outcomes.
