[Studies and clinical experiences in the use of domestic blood vessel prostheses with increased thromboresistance].
The experimental and clinical data on the use of new native grafts with increased thromboresistance--the Vitlan and heparinized ones are presented. In all the acute and chronic experiments, the increased thromboresistance of both types of the grafts versus the common Fluorlon-Lavsan ones, and well-formed neointima with sufficient vascularization by the year 1 and 5 of follow-up were revealed. Complete organization of the external and internal capsules of the grafts was noted 5 mos later, no tissue reaction to Vitlan and heparinized grafts was revealed. The Vitlan grafts were used in 19 patients. Good immediate and long-term results were obtained in reconstruction of the aorto-femoral, aorto-pulmonary and femoro-popliteal segments with the grafts of 10 and 8 mm in diameter. All the Vitlan shunts of the femoro-popliteal segment with 6 mm diameter were thrombosed 1-6 mos after the operation. The heparinized grafts with 8 mm diameter at the femoro-popliteal position were used in 28 patients, good long-term results were noted in 27.
