METHOD FOR FORMING A microvascular anastomosis

机译:形成微血管吻合的方法

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely to vascular surgery. One fixing suture is applied on both donor and recipient vessels in lateral walls of vessels. After that, on the wall of recipient vessel performed is transversal cut with size 2-3 mm × 0.5-1.0 cm above anastomosis zone. Through said cut catheter provided with strent is introduced into vessel lumen. Stent is guided into lumen of donor vessel in such a way that half of stent is in donor vessel, and half is in recipient vessel. Catheter is removed ensuring stent extension with its opening under the impact of vessel lumen. Vessels in anastomosis zone are fixed with interrupted sutures, 2-3 suturess are applied in area of performed transversal cut.;EFFECT: method makes it possible to ensure contact of vessels with homogeneous layers on anastomosis line; absence of anastomised vessels of muscular envelope or adventitial cover in lumen; smoothness of vessel surface in anastomosis zone and absence of bends; to prevent injuries in anastomosis area and along vessel length due to absence in stent of perforating as well as cutting ability; to avoid contact of blood passing through vessel with threads; to support specified diameter of vessel lumen, which facilitates normal blood flow in place of connection; to provide possibility of applying even both in thickness and in distance from vessel edge, stitches; to ensure reduction of time of anoxia of vessel and fed by it tissues due to reduction of surgery time.;1 dwg, 2 ex
