(5) СПОСОБ ЗАГОТОВКИ ВЕНОЗНЫХ АЛЛОТРАНСПЛАНТАТОВ(5) METHOD FOR PREPARING VENOUS ALLOTRASPLATS
Изобретение относитс к медицине, а именно к сосудистой хирургии и быть использовано при лечении непроходимости кровеносного руспа.The invention relates to medicine, namely to vascular surgery, and to be used in the treatment of obstruction of the bloodstream.
Известен способ заготовки венозных аллотрансплантатов путем перев зки притоков магистральной вены, иссечени и помещени ее в консервирующую жидкость р .There is a known method of preparing venous allografts by bandaging the inflows of the main vein, dissecting it and placing it in a preserving fluid p.
Однако известный способ не обеспечивает нивелировки просветов сосудистых трансплантатов на их прот жении и тем самым не устран ет трудностей, св занных с осуществлением последующего соединени разнокалиберных соСУДов . Различи же в диаметрах соедин емых сосудов порождают значительные трудности при выполнении анастомоза и привод т к снижению его качества . Кроме того,в местах резкого изменени просвета кровеносного русла (по линии проксимального и дистального анастомозов) нарушаетс ламинарна структурность кровотока и возникают его завихрени . Все эти факторы повышают опасность развити тромбозов как одного из т желых осложнени после пластических вмешательств на кровеносных сосудах.However, the known method does not provide leveling of the lumens of the vascular grafts throughout them and thus does not eliminate the difficulties associated with the implementation of the subsequent connection of mixed calibers. Differences in the diameters of the connected vessels create considerable difficulties in the performance of the anastomosis and lead to a decrease in its quality. In addition, in places of abrupt changes in the lumen of the circulatory bed (along the line of the proximal and distal anastomoses), the laminar structure of the blood flow is disturbed and turbulence occurs. All of these factors increase the risk of developing thrombosis as one of the most severe complications after plastic surgery on blood vessels.
Цель изобретени - обеспечение нивелировки просветов сосудистых трансплантатов на их прот жении.The purpose of the invention is to provide leveling of the lumens of the vascular grafts throughout them.
Указанна цель достигаетс тем, что при осуществлении способа заготовки венозных аллотрансплантатов путем перев зки притоков магистральной вены, иссечени и помещени ее в консервирующую жидкость, трансплантат помещают в цилиндр с перфорированными стенками, концы трансплантата перев зывают, а в просвет вены нагнетают консервирующую жидкость до пределов, Обеспечивающих плотное соприкосновение стенок вены цилиндра, и затем цилиндр вместе с веной помещают в консервирующую жидкость на 10-15 дней.This goal is achieved by the fact that, in carrying out the method of preparing venous allografts by bandaging the inflows of the main vein, excision and placing it in a preserving fluid, the graft is placed in a cylinder with perforated walls, the ends of the graft are intertwined, and the preservative fluid is bound in the lumen of the graft, Providing a tight contact of the vein walls of the cylinder, and then the cylinder together with the vein is placed in a preservative liquid for 10-15 days.
