[The pathogenesis and surgical treatment of trophic ulcers of the lower extremities against a background of varicose veins].

The state of the musculo-venous pump of lower extremities was studied in 72 patients with trophic ulcers caused by varicose disease. The methods used were: phlebotonometry, phleboplethysmography, US dopplerography, distal ascending and retrograde-femoral, popliteal and talocrural phlebography. It was established that ectasia and/or valve incompetence of deep and muscle veins of the lower extremities with the formation of blood refluxes along the profound, communicating and superficial veins underlie the disturbances of venous hemodynamics. The authors propose a scheme of pathogenesis of the varicose disease trophic ulcers and recommend to perform pathogenetically justified operations.
