Аллографт лёгочной артерии консервирован в растворе «Кустодиол» и сохранён в условиях умеренной гипотермии (+4°C) до 60 суток. Выполнены гистологические срезы толщиной 3–6 мкм, которые окрашивали гематоксилином и эозином, пентахромной окраской по Мовату — Расселу. Оценивалось состояние мышечно-эластического слоя стенки лёгочной артерии. Гистологическое исследование показало, что через 1–2 суток консервации структура мышечно-эластического слоя донорской легочной артерии сохранена; к 3–4 суткам появились гиперхромия ядер, отёк межклеточного матрикса, истончение внутренней эластической мембраны. С 5–6 суток выявлены первые признаки гибели гладкомышечных клеток, расслоение мышечной оболочки. К 8–10 суткам усилились дезорганизация эластического каркаса, отёк и набухание мышечно-эластического слоя стенки лёгочной артерии, определялись явные признаки гибели гладкомышечных клеток. К 16–18 суткам эластические волокна стали фрагментированными. К 30 суткам нарастали некробиотические изменения клеток, отмечена гомогенизация внутренней эластической мембраны. К 50–60 суткам сохранялись лишь единичные группы гладкомышечных клеток, эластический каркас был конденсирован и фрагментирован. Результат: изменения мышечно-эластического слоя аллографта лёгочной артерии характеризуются постепенной гибелью гладкомышечных клеток с отёком и дезорганизацией стромы на фоне относительного сохранения эластического каркаса. Структурная целостность и жизнеспособность ткани донорской легочной артерии сохраняются до 6 суток консервации в растворе «Кустодиол» при +4°C.</p></abstract><trans-abstract xml:lang="en"><p>A study was conducted on segments of the pulmonary artery retrieved from donors following the confirmation of brain death. The pulmonary artery allograft was preserved in «Custodiol» solution and stored under conditions of moderate hypothermia (+4°C) for up to 60 days. Histological sections 3–6 μm thick were prepared and stained with haematoxylin and eosin, and with the Movat–Russell pentachrome stain. The condition of the muscular-elastic layer of the pulmonary artery wall was assessed.Histological examination showed that after 1–2 days of preservation, the structure of the muscular-elastic layer of the donor pulmonary artery was preserved; by days 3–4, nuclear hyperchromia, oedema of the intercellular matrix and thinning of the internal elastic membrane had appeared. From days 5–6, the first signs of smooth muscle cell death and delamination of the muscular layer were observed. By days 8–10, the disorganisation of the elastic framework, oedema and swelling of the muscular-elastic layer of the pulmonary artery wall had intensified, and clear signs of smooth muscle cell death were evident. By days 16–18, the elastic fibres had become fragmented. By day 30, necrobiotic changes in the cells were increasing, and homogenisation of the internal elastic membrane was observed. By days 50–60, only isolated groups of smooth muscle cells remained; the elastic framework was condensed and fragmented.Consequently, changes in the muscular-elastic layer of the pulmonary artery allograft are characterised by the gradual death of smooth muscle cells, accompanied by oedema and disorganisation of the stroma, against a background of relative preservation of the elastic framework. The structural integrity and viability of the donor pulmonary artery tissue are maintained for up to 6 days of preservation in «Custodiol» solution at +4°C.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сосудистый аллографт</kwd><kwd>лёгочная артерия</kwd><kwd>консервация</kwd><kwd>гипотермия</kwd><kwd>жизнеспособность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vascular allograft</kwd><kwd>pulmonary artery</kwd><kwd>preservation</kwd><kwd>hypothermia</kwd><kwd>viability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках финансирования РНТП «Разработать и внедрить метод органосохраняющего хирургического лечения заболеваний или патологических состояний, требующих реконструкции или замещение лёгочной артерии при резекциях лёгких» по договору № РНТП-11/2025 от 24.03.2025 г.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Использование сосудистых графтов / К.
