An analysis of results of the endovenous laser coagulation combined with crossectomy was made in 170 patients with varicose veins of lower extremities (C(VI), C(II)-C(V)). Clinical and ultrasonic data were investigated during a period of 3-5 days (45 lower extremities) and followed up in 1-3 years after operation (194 lower extremities). Three years later the absence of reflux was observed in 95.9% of cases. In 51.1% of cases, 1-2 zones of parietal and segmental hemodynamical insignificant bloodstream were detected. A recanalization of the great saphenous vein along the whole length was revealed in 8 cases out of 194 (4.1%) patients. The bloodstream was provided by affluxes in the area of a shin and a wellhead afflux of the stump of the great suphenous vein. The ultrasonic picture of recanalization was similar to that observed in post-thrombophlebitic occlusion.
