All the grafts were patent during the whole period of implantation. Twelve months postimplantation, 25% of the grafts were intact, and 25% of the grafts had parietal thrombus only at anasthomotic sites and thrombusfree surface at all other sites Regarding other grafts, we revealed minor connective tissue hyperplasia in 41 7% of the grafts, and an inflammatory infiltrate in the part of the arterial wall in 8. 3% of the grafts. Using original technique of the morphological investigation, we found that polymer degradation was accompanied by the replacement of the graft wall by various cells (macrophages, fibroblast-like cells, epithelioid cells, and multinucleated giant cells) with the formation of extracellular matrix instead of the polymer scaffold Therefore, long-term patency and the results of the morphological study confirmed the possibility to use PHBV/PCL tubular polymer construct in the creation of small-diameter vascular grafts</p></abstract><trans-abstract xml:lang="ru"><p>Изучена интеграция с клетками и тканями организма биодеградируемых сосудистых графтов, изготовленных методом электроспиннинга из полигидроксибутирата/валерата и поликапролактона. Графты были имплантированы в брюшную часть аорты крыс линии Wistar на 12 мес. В течение всего срока имплантации графты оставались проходимы. При гистологическом исследовании 25% эксплантированных графтов не имели проблемных зон, в 25% графтов выявлена фиброзно-тромбоцитарная выстилка в зонах анастомозов, в 41,7% - незначительная гиперплазия соединительной ткани в просвете, в 8,3% - частичная воспалительная инфильтрация стенки При дополнительном морфологическом исследовании графтов по оригинальной методике авторов выявлено, что деградация полимера сопровождалась замещением стенки графтов клетками разных типов (макрофагами, фибробластоподобными, эпителиоидными и гигантскими многоядерными клетками) с формированием собственного внеклеточного матрикса на месте полимерного каркаса Таким образом, долгосрочная проходимость и результаты комплексного морфологического исследования подтвердили пригодность созданной трубчатой полимерной конструкции из полигидроксибутирата/валерата и поликапролактона выступать в качестве основы для создания различных вариантов гибридных сосудистых графтов малого диаметра.</p></trans-abstract><kwd-group xml:lang="en"><kwd>biocompatible biodegradable polymers</kwd><kwd>small-diameter vascular graft</kwd><kwd>morphological studies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>биосовместимые биодеградируемые полимеры</kwd><kwd>сосудистый имплант малого диаметра</kwd><kwd>морфологическое исследование</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Бокерия Л.А., Беришвили И.И., Солнышков Л.Э. и др.
