[State of crural perforating veins after sclerosurgical interventions for lower limb varicose disease].

Analysed herein are the findings obtained by comprehensive examination of 106 patients presenting with grade C3 chronic venous insufficiency according to the CEAP classification. Localization, intensity and extent of refluxes of blood in the venous system of the affected extremity were determined by means of ultrasonographic angioscanning. Based on the obtained results, the patients were subdivided into two groups. Group One was composed of 87 (82.1%) patients found to have their perforant venous insufficiency caused by superficial hypervolemia due to sharply pronounced varicosity of superficial veins. Group Two comprised 19 (17.9%) patients who had developed perforant insufficiency secondary to superficial and deep blood refluxes. In 82 (77.3%) Group One patients, the scope of the operations was limited to elimination of the superficial blood reflux, with only five (4.7%) patients at the second stage of management had their perforant blood reflux removed. Group Two patients were subjected to single-stage removal of both superficial and perforant blood refluxes. Excellent therapeutic outcomes were observed in 49.1% of cases, with good and satisfactory results obtained in 41.5% and 9.4% of patients, respectively.
