Description

Изобретение относитс  к медицине, а именно к протезированию сосудов искусственными трансплантатами.The invention relates to medicine, namely to vascular prosthetics with artificial grafts.

Цель изобретени  - снижение частоты послеоперационных осложнений при ал- лопротезировании путем повышени  атром- богенности протеза.The purpose of the invention is to reduce the incidence of postoperative complications in alloplastic prosthetics by increasing the prosthesis.

Способ осуществл ют следующим образом .The method is carried out as follows.

После резекции сегмента артерии в образовавшийс  дефект сосуда вшивают искусственный протез с предварительно надетым на него вторым протезом большего диаметра и длиной на 4-9 мм меньше первого . Кра  второго протеза приклеивают к вшитому протезу, а в пространство между ними ввод т раствор с эндотелиальными клетками.After resection of the artery segment, an artificial prosthesis is inserted into the resulting vascular defect with a second prosthesis of a larger diameter previously placed on it and a length of 4–9 mm less than the first. The edges of the second prosthesis are glued to the inserted prosthesis, and a solution with endothelial cells is introduced into the space between them.

Пример. Разрезом на шее у собаки выделены сонные артерии. Пережата обща  сонна  артери , резецирована на прот жении 60 мм. Образовавшийс  диастаз замещен фторлонлавсановым протезом диаметром 8 мм с предварительно надетым на него вторым протезом диаметром 10 мм, кра  которого приклеены к поверхности первого протеза с помощью медицинского кле , а длина на 6 мм меньше первого. Двойной протез заполнен физиологическим раствором с гепарином, после вшивани  по протезу кратковременно пущен кровоток, в течение 1-2 с. Через 6-7 мин после этого в пространство между протезами введена приготовленна  суспензи  эндотелиальных клеток с питательной средой. После этого кровоток восстановлен .Example. The dog's carotid arteries are cut through the neck. The common carotid artery was clamped, resected over 60 mm. The resulting diastasis is replaced by a 8 mm diameter fluorine coated prosthesis with a second 10 mm diameter prosthesis previously put on it, the edges of which are glued to the surface of the first prosthesis with medical adhesive, and the length is 6 mm less than the first. The double prosthesis is filled with physiological saline with heparin; after the lining along the prosthesis, the blood flow is briefly started for 1-2 s. After 6-7 minutes after this, a prepared suspension of endothelial cells with a nutrient medium was introduced into the space between the prostheses. After that, blood flow is restored.

Способ использован в 14 экспериментах , срок наблюдени  составил до 1.5 лет. Во всех случа х при контрольном исследовании получена качественна  выстилкаThe method was used in 14 experiments, the observation period was up to 1.5 years. In all cases, the control study obtained quality lining
