RESUMO
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.

A possibility of detection of BRAF mutation has been studied by means of polymerase chain reaction in punctate from the thyroid node with the aim of diagnostics of high-differentiated cancer on pre-operative stage. A study includes 94 patients with nodal lesions of the thyroid. According to cytological investigation of material, received by fine-needle aspiration biopsy, papillary thyroid cancer was revealed in 47 patients, follicular tumor-in 35 and nodal colloid goiter in 12 patients. In case of papillary thyroid cancer data of genetic analysis showed the following indices of sensitivity, specificity and diagnostic accuracy: 86%, 100% and 92% correspondingly. Detection of BRAF mutation could be used in pre-operative differential diagnostics of high-differentiated cancer and benign nodal lesions of the thyroid.
