This research evaluated a long-term passability and geometric stability in the area of plasty at the first-second days and after 6, 12, 48 months after surgical reconstruction in 35 patients, who underwent endarectomy. The plasty of arteriotomic opening was performed using autovenous patch (segment of saphenous vein) in 19 patients. An application of synthetical patch (Carotid patch 6 mm) was carried out in 16 cases. According to obtained data, an increase of diameter in bifurcation area of arteria carotis was revealed in group of patients with autovenous plasty 15 (78,95%) at the first 12 months after operation. There weren’t observed any enlargement of the plasty area in following period. The diameter of bifurcation area has reached 2,0 cm in mean diameter OSA 0,74 cm in 5 patients out of 19 (26%). A dilatation of anastomosis area was detected in 5 patients out of 16 (31,25%) in group with plasty of arteriotomic opening by synthetical patch. All patients with dilatation anastomosis had arterial hypertension, which was one of the main factors of dilatation development of plasty area.
