摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to surgery. Perform preoperative ultrasound and Doppler study with the determination of the state of the vessels, the diameter of the vein and artery, the speed of blood flow. When conducting Doppler study, the resistivity index Ri is also determined in a sample with a clenched fist. Formation of arteriovenous fistula is performed at Ri value from 0.55 to 0.75. When the artery is cut at the anastomosis site, a transverse incision of 0.2–0.3 cm is first made and then the artery is dissected from its center along 1.0–1.2 cm. After the anastomosis is formed, an extravasal bandage is applied to the vein, anastomosis a vascular prosthesis of length of 1.5–2.0 cm is used as the extravasal bandage, which is previously dissected along, and then the vein is wrapped with the resulting web. At the same time, one side of the prosthesis is combined with the outer perimeter of the anastomosis and fixed, then the web walls are sewn along the vein, gradually reducing the diameter to 0.6–0.7 cm. Surplus of the web is excised.EFFECT: method allows to carry out preventive personalized prevention of high-flux arteriovenous fistulas, as a result it increases the duration and quality of life of this category of patients, reduces the need for inpatient treatment and surgical interventions, and reduces the risk of thrombosis.1 cl, 3 dwg, 2 exИзобретение относится к медицине, а именно к хирургии. Выполняют предоперационное УЗИ и доплерографическое исследование с определением состояния сосудов, диаметра вены и артерии, скорости кровотока. При проведении доплерографического исследования дополнительно определяют индекс резистивности Ri по пробе со сжатым кулаком. Формирование артериовенозной фистулы осуществляют при значении Ri от 0,55 до 0,75. При рассечении артерии в месте анастомоза сначала делают поперечный разрез 0,2-0,3 см, а затем от его центра рассекают артерию вдоль на 1,0-1,2 см. После формирования анастомоза на вен
