Проведены исследование когнитивных показателей и сцинтиграфия головного мозга у 45 пациентов с МФА коронарных и прецеребральных артерий до и после реваскуляризации этих сосудистых бассейнов. Критериями включения в исследование явились: планирующаяся реваскуляризация коронарных и прецеребральных артерий, подписанное информированное добровольное согласие на участие в исследовании. Критерии исключения: отказ пациента, наличие у него заболеваний, препятствующих проведению обследований. Исследование когнитивных функций выполняли на программно-аппаратном комплексе Status-PF за 1–2 дня до операции и через 5–7 дней после нее. Сохранность мозгового кровотока оценивали методом однофотонной эмиссионной компьютерной томографии с использованием липофильного радиофармацевтического препарата 99mTc-HMPAO «Церетек».Результаты. Частота ранней ПОКД у больных после изолированного коронарного шунтирования (КШ) составила 73,3%, у пациентов после симультанной операции КШ и каротидной эндартерэктомии (КЭА) – 72,5% (р ˃ 0,05). Показатель рМК у пациентов группы изолированного КШ по сравнению с группой симультанной операции КШ и КЭА был выше в височных областях справа и слева (р = 0,01 и р = 0,04), в правой лобной доле (р = 0,03), правой теменной доле (р=0,005), а также в затылочных долях справа и слева (р = 0,03 и р = 0,03). В послеоперационном периоде по сравнению с дооперационным значением в группе изолированного КШ снижался уровень перфузии в правой теменной области (р = 0,01), в правой и левой затылочных областях (р = 0,01 и р = 0,01). У пациентов группы симультанного вмешательства значение показателей рМК значимо не менялись в раннем послеоперационном периоде. Перфузия правой теменной области была выше у больных после изолированного КШ по сравнению с данным показателем у пациентов после симультанной операции КШ и КЭА (р = 0,04). Наибольший вклад в развитие ранней ПОКД у больных после изолированного КШ внесли показатели рМК левой височной области (р = 0,025), у пациентов после симультанной операции КШ и КЭА – в правой теменной зоне (р = 0,04) в раннем послеоперационном периоде.Заключение. Оценка перфузии головного мозга у кардиохирургических пациентов до и после операции может использоваться для выявления зон, пострадавших при проводимых вмешательствах, а также быть методом контроля безопасности операций и оценки применяемых способов профилактики для предотвращения развития ПОКД.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to study the contribution of regional cerebral blood flow (rCBF) indicators to the diagnosis of early postoperative cognitive dysfunction (POCD) in patients with multifocal atherosclerosis (MFA) with heart and brain revascularization.Material and methods. The study involved 45 patients with MFA of coronary and precerebral arteries. We analyzed patients’ cognitive indicators and conducted brain scintigraphy before and after revascularization. The criteria for inclusion in the study were: scheduled combined revascularization of coronary and precerebral arteries; signed informed consent to participate in the study. Criteria for exclusion were: refusal to participate in the study, diseases that would prevent examination. The study of cognitive functions was performed using flow was assessed by single-photon emission computed tomography using lipophilic radiopharmaceutical 99mTc-HMPAO “Ceretec”.Results. The frequency of early POCD in the isolated coronary artery bypass grafting (CABG) group was 73.3%, in the combined carotid endarterectomy (СEA) and CABG group it was 72.5% (p ˃ 0.05). The rCBF index in the isolated CABG group compared with the combined СEA and CABG group was higher in the right and left temporal lobes (p = 0.01 and p = 0.04), in the right frontal lobe (p = 0.03), right parietal lobe (p = 0.005), and in the right and left occipital lobes (p = 0.03 and p = 0.03). In the postoperative period, in the isolated CABG group, right parietal lobe perfusion (p = 0.01), and right and left occipital lobe perfusion (p = 0.01 and p = 0.01) decreased compared to the baseline values. In the combined СEA and CABG group, in the early postoperative period, cerebral perfusion did not change significantly. Right parietal lobe perfusion was higher in the isolated CABG group compared with the combined CABG and СEA group (p = 0.04). The greatest contribution to the development of early POCD in patients after isolated CABG was made by the left temporal lobe perfusion (p = 0.025), in patients after combined CABG and СEA – by the right parietal lobe perfusion (p = 0.04) in the early postoperative period.Conclusion. Assessment of cerebral perfusion in patients before and after surgery can be used to identify areas affected during surgery, as a method for monitoring the safety of procedure, and as an assessment of the preventive methods against POCD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стеноз прецеребральных артерий</kwd><kwd>симультанная операция</kwd><kwd>коронарное шунтирование</kwd><kwd>каротидная эндартерэктомия</kwd><kwd>когнитивные функции</kwd><kwd>сцинтиграфия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>precerebral arteries stenosis</kwd><kwd>combined surgery</kwd><kwd>coronary artery bypass surgery</kwd><kwd>carotid endarterectomy</kwd><kwd>cognitive functions</kwd><kwd>scintigraphy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках фундаментальной темы НИИ КПССЗ «Мультифокальный атеросклероз и коморбидные состояния.
