. The most common complication of the vascular access for hemodialysis, that can lead to its loss, is thrombosis. The method of choice in diagnosing fistula thrombosis is duplex ultrasound. Purpose : to study the ultrasound signs and changes in hemodynamics data in thrombosed fistulas and to determine the risk factors contributing to its development. Materials and methods . Duplex ultrasound was performed in 550 patients with vascular access for hemodialysis. Access thrombosis was detected in 12,0%, non-occlusive thrombosis was observed in 60,6%, occlusive thrombosis — in 39,4%. Thrombosis was significantly more common in women than in men (p=0,025). In patients with graft, thrombosis was more common (24,2%) than in those with arteriovenous fistula (11,2%), p=0,026. A correlation was found between the presence of significant vascular access stenosis, aneurysm of the outflow vein or graft, and the development of thrombosis (p<0,02). Duplex ultrasound allows to diagnose vascular access thrombosis and to determine the causes of its development.
