Abstract
The invention relates to medicine, namely to cardiac surgery and can be used for effective prevention of bleeding, thrombosis, and fistula formation.The objective of the invention is to develop a method for implanting a composite conduit in ascending aortic aneurysm using supraannular prosthetics on patches with Π-shaped sutures, for effective 100% prevention of bleeding, thrombosis, and fistula formation.The technical result of the invention is to confer the following properties: effective 100% prevention of bleeding, thrombosis, and fistula formation.This technical result is achieved by threads pulled from the prosthesis cuff are applied to the outer surface of the aorta and are fixed on the patches, thereby effectively preventing bleeding due to complete wrapping and sealing of the cuff.Thrombosis does not occur due to complete isolation of the conduit cuff and absence of fixation sutures in the aorta lumen, preventing fistula formation.
