[Effectiveness of biological prosthesis for femoro-femoral bypass in high risk patients].

Aim: To compare synthetic and biological prostheses for femoral bypass surgery.

Material And Methods: There were 40 patients with critical ischemia of lower extremities due to atherosclerotic lesion of aorto-iliac segment and severe comorbidities. They were divided into 2 groups by 20 patients. C-shaped femoro-femoral bypass with synthetic polytetrafluoroethylene and lavsan prostheses was performed in the first group and S-shaped bypass procedure with biological prosthesis from the internal thoracic arteries of the bull - in the second group.

Results: Biological prosthesis is associated with reduced early postoperative morbidity by 10%, late graft thrombosis incidence by 20% and increased physical and psychological health by 7.1%.

Conclusion: S-shaped femoro-femoral bypass with a biological prosthesis from the internal thoracic arteries of the bull is pathogenetically substantiated and effective.
