METHOD AND DEVICE FOR PREVENTING ANEURYSM OCCURRENCE IN REPAIRING AORTA AND LARGE ARTERIES

摘要

FIELD: medicine; medical engineering.;SUBSTANCE: method involves creating central end-to-end anastomosis of blood vessel and synthetic prosthesis. Porous titanium nickelide device of 50-65% porosity and pore size of 50-200 mcm, is conducted through peripheral vascular prosthesis end. The cylindrical device is not shorter as 25 mm and has longitudinal slit. The device is set in a way that the slit and anastomosis line are overlapped with the cylinder at distance not shorter than by 5 mm and aorta segment adjacent to the prosthesis at 25 mm long distance. The longitudinal slit is arranged on blood vessel wall with slightest deviation and fixed on both sides with 2-3 sutures.;EFFECT: accelerated operation time; reduced risk of traumatic complications.;2 cl, 2 dwg
