Морфофункциональная целостность структур стенки венозного кондуита при коронарном шунтировании является гарантом функционирования аутовенозных шунтов в отсроченном периоде. Выделение вены в лоскуте с окружающими тканями обеспечивает минимальное воздействие на вену с лучшими результатами в отдаленном периоде, но увеличивает риск раневых осложнений. Эндоскопическое выделение вены способствует значимому снижению раневых осложнений, но, по литературным данным, может отрицательно сказываться на проходимости шунтов вследствие влияния механических манипуляций и воздействия углекислого газа. Ранее нами был разработан метод эндоскопического выделения вены в лоскуте с окружающими тканями, не требующий инсуффляции углекислого газа.Цель исследования: оценка морфофункциональных изменений фрагментов вен, выделенных оригинальнымэндоскопическим методом, по сравнению с традиционным открытым забором.Материал и методы. На исследование отправлялись фрагменты большой подкожной вены после эндоскопического и открытого выделения. Из доступа в области колена открыто выделялся фрагмент вены 3–5 см, который использовался затем для биопсии контрольной группы. Далее вена выделялась эндоскопически, фрагменты этой части вены вошли в исследуемую группу. Проводилась световая микроскопия с окраской гематоксилином и эозином для оценки структурной целостности стенки вен, а также иммуногистохимическое определение экспрессии CD 31 и Е-кадгерина для оценки жизнеспособности и функциональности эндотелия.Результаты. По данным гистологического исследования, в сегментах, выделенных эндоскопическим путем, отмечен более сохранный эндотелий, по данным иммуногистохимии, более жизнеспособный эндотелий.</p></abstract><trans-abstract xml:lang="en"><p>Background. The morpho-functional integrity of the structures of the wall of the venous conduit during coronary artery bypass grafting is the guarantor of the functioning of autovenous bypass grafts in the long-term period. Allocating a vein in a flap with surrounding tissues ensures minimal effect on the vein with better results in the long-term, but it increases the risk of wound complications. Endoscopic vein harvesting contributes to a significant reduction in wound complications. However, according to literary data, this technique can negatively affect the bypass grafts passability due to the effects of mechanical manipulations and exposure to carbon dioxide. Previously, we developed a method for the endoscopic vein extraction in a flap with surrounding tissues that does not require carbon dioxide insufflation.Aim. The aim of the study was to assess the morphological and functional changes in the vein fragments harvested by the new original endoscopic method compared to the traditional open harvesting technique.Material and Methods. The fragments of the great saphenous vein were studied after endoscopic and open harvesting. From the access in the knee area, a 3–5 cm fragment of the vein was openly harvested and was then used for the biopsy in the control group. Next, the vein was harvested endoscopically and the fragments of this part of the vein comprised the study group. Light microscopy of the sections, stained with hematoxylin and eosin, was performed to assess the structural integrity of the venous walls; the expression of CD 31 and E-Cadherin was determined immunohistochemically to assess the viability and function of the endothelium.Results. The results of histological study suggested that the endothelium was more intact in the segments harvested endoscopically; moreover, immunohistochemistry data showed that the endothelium was more viable in these segments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коронарное шунтирование</kwd><kwd>минимально инвазивная хирургия</kwd><kwd>эндоскопия</kwd><kwd>морфология</kwd><kwd>иммуногистохимия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronary artery bypass surgery</kwd><kwd>minimally invasive surgery</kwd><kwd>endoscopy</kwd><kwd>morphology</kwd><kwd>immunohistochemistry</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dashwood M.R., Loesch A.
