Сосудистые графты диаметром 2 мм изготавливали из поликапролактона (PCL) и смеси полигидроксибутирата/валерата (PHBV) и поликапролактона методом электроспиннинга. Модификацию графтов молекулами VEGF осуществляли двухфазным электроспиннингом. Морфологию изготовленных графтов оценивали методом сканирующей электронной микроскопии. Физико-механические свойства PCL и PHBV/PCL оценивали по результатам одноосного растяжения и исследования комплаентности. Для PCL/VEGF- и PHBV/PCL/VEGF-графтов проводили физико-механические испытания до и после имплантации в брюшную аорту крыс на срок 6 месяцев. Моделирование работы модифицированных графтов осуществляли методом конечных элементов в случае аортокоронарного шунтирования (АКШ).</p></sec><sec><title>Результаты</title><p>Результаты. PCL- и PHBV/PCL-графты по прочности не уступали внутренней грудной артерии человека, но обладали большей жесткостью и способностью к растяжению, а также по вязкоэластическим свойствам были приближены к нативным сосудам. Модификация графтов VEGF спообствовала снижению жесткости материалов. После 6 месяцев имплантации PCL/VEGF- и PHBV/PCL/ VEGF-графты интегрировались с тканями аорты, что способствовало изменению физико-механических свойств графтов в соответствии со свойствами нативного сосуда. Биомеханическое моделирование подтвердило возможность функционирования модифицированных графтов в позиции шунта при АКШ.</p></sec><sec><title>Заключение</title><p>Заключение. PCL/VEGF- и PHBV/PCL/VEGF-графты обладают удовлетворительными физико-механическими свойствами и потенциально пригодны для использования при реконструкции кровеносных сосудов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to evaluate the biomechanical remodeling of polymer grafts modified with vascular endothelial growth factor (VEGF) after implantation into rat abdominal aorta.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Vascular grafts of2 mmdiameter were fabricated by electrospinning from polycaprolactone (PCL) and a mixture of poly (3-hydroxybutyrate-co-3-hydroxyvalerate) and PCL. The grafts were modified with VEGF by biphasic electrospinning. Morphology of the grafts was assessed by scanning electron microscopy. Physico-mechanical properties of PCL and PHBV/PCL grafts were estimated using uniaxial tensile test and physiological circulating system equipped with state-of-theart ultrasound vascular wall tracking system. Physico-mechanical testing of PCL/VEGF and PHBV/PCL/VEGF was performed before and after implantation into rat abdominal aorta for 6 months. The modeling of coronary artery bypass grafting (CABG) was performed by finite element analysis for modified grafts.</p></sec><sec><title>Results</title><p>Results. Durability of PCL and PHBV/PCL grafts did not differ from that of human internal mammary artery; however, elasticity and stiffness of these grafts were higher compared to internal mammary artery. Viscoelastic properties of the grafts were comparable to those of native blood vessels. Modification of the grafts with VEGF reduced material stiffness. Six months postimplantation, PCL/VEGF and PHBV/PCL/VEGF were integrated with aortic tissue that induced changes in the physico-mechanical properties of the grafts similar to the native vessel. Biomechanical modeling confirmed the functioning of modified grafts in bypass position for CABG.</p></sec><sec><title>Conclusion</title><p>Conclusion. PCL/VEGF and PHBV/PCL/VEGF grafts have satisfactory physico-mechanical properties and can be potentially used in the reconstruction of blood vessels. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>поликапролактон</kwd><kwd>полигидроксибутират/валерат</kwd><kwd>сосудистый эндотелиальный фактор роста</kwd><kwd>сосудистый графт</kwd><kwd>электроспиннинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polycaprolactone</kwd><kwd>polyhydroxybutyrate/valerate</kwd><kwd>vascular endothelial growth factor</kwd><kwd>vascular graft</kwd><kwd>electrospinning</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">Roth GA, Forouzanfar MH, Moran AE, Barber R, Nguyen G, Feigin VL et al.
