Abstract: Изобретение относится к медицине, а именно к сосудистой хирургии. Выделяют аутовену из протяженных разрезов над предварительно размеченной аутовеной, с последовательной перевязкой и пересечением всех притоков. При этом аутовену отсекают в области сафенофеморального соустья, тогда как дистальную часть вены оставляют не пересеченной, сохраняя естественное течение крови по ней. Проксимальную часть аутовены выводят из раны. Накладывают дистальный анастомоз с подколенной или берцовой артерией. После наложения дистального анастомоза между реверсированной частью аутовены, без наложения узла на анастомоз, отсекают дистальный конец аутовены и перевязывают остающуюся часть. В просвет, отсеченной для шунта аутовены, устанавливают иглу Дебейки. Дистальный конец аутовены путем перевязки на игле временно фиксируют к оливе. К концу иглы присоединяют шприц со смесью физиологического раствора с гепарином с температурой 36-37°С, и с помощью шприца, не создавая высокого давления, проверяют герметичность аутовены и промывают ее от остатков крови. Затем аутовену проводят вдоль мышц, накладывают дистальный анастомоз, и после пуска кровотока завязываются узлы последовательно на проксимальном и дистальном анастомозе. Способ позволяет избежать ранних и поздних осложнений, связанных с тромбозом шунта и возвратом клиники ишемии, вернуть трудоспособность и улучшить качество жизни больных заболеваниями периферических артерий, после операции шунтирования реверсированной аутовеной. 1 пр.
