Pathological changes of the vascular walls in patients with varicose disease of the lower extremities after endovasal laser obliteration and radiofrequency ablation
Abstract
In modern surgery the most effective ways of treating varicose veins of the lower extremities is endovascular method of surgical treatment. We conducted a comparison of the pathological changes of the venous walls in patients with varicose disease of lower limb after endovenous laser treatment and radiofrequency ablation. Microscope slides was prepared by a standard method. Performed microscopy and photographed histological specimens. Morphometry was performed. Determined that after endovenous laser coagulation dominated coagulative necrosis which extended up to 1/3 of the average of the middle layer of the vein, and in patients after radiofrequency ablation depth of necrosis was within endothelial and subendothelial layer, characteristic was the detachment of the endothelium from the lungs of the vessel lumen.
