[Possibilities of improving the methods of making vascular prostheses using human umbilical veins]

In the experiment, the possibilities for intensification and acceleration of the umbilical vein tissue stabilization, increasing the strength and improving the plastic properties, increasing the resistance of biological grafts to thrombosis due to the use of the improved method of conservation according to the scheme: dynamic stabilization in the glutaraldehyde-enzyme-glutaraldehyde-heparin solution are studied. The developed biological grafts were used in 12 patients with occlusion of the arteries of the femoropopliteal segment. After 18 mos, the grafts are patent in 8 patients.
