Objective: to identify predictors of cerebral embolism associated with carotid angioplasty with stenting (CAS). Material and methods. A prospective exploratory research included 46 patients (age from 44 to 81 years, median 65 years) with atherosclerotic stenosis of the internal carotid artery, who underwent CAS and were treated at the Scientific Center of Neurology (Moscow). The study did not include patients with restenosis, stroke with severe disability, contraindications for antiplatelet therapy, statins, and MRI examination. All patients underwent preoperative ultrasonographic (US) examination and postoperative histological examination of particles in carotid stent embolic protection devices. The state of the brain was assessed before and 24 hours after CAS using diffusion-weighted MRI. To identify predictors of the development of cerebral embolism, the clinical characteristics of patients, together with ultrasonographic and morphological data, were examined in a multivariate statistical analysis.Results. Preoperative US signal from an atherosclerotic plaque of high (estimated above 35 dB) intensity was associated with dense matter (in a protective device) of the "fibrosis with calcification" and "calcification" type and with a high probability (80%; 95% confidence interval 71–85% ) predicted intraoperative embolization of cerebral vessels with the acute ischemic lesions (AIL) formation. In a low (not higher than 35 dB) intensity of the preoperative ultrasound signal, the probability of AIL formation was statistically significantly lower (50%). Conclusion. There is a direct correlation between the intensity of the ultrasound signal and the density of the substance in the protective device. A high intensity of the preoperative ultrasound signal (estimated above 35 dB) is an unfavorable predictor of AIL, associated with CAS (with a probability of about 80%).</p></abstract><trans-abstract xml:lang="ru"><p>Стентирование сонных артерий является действенным методом улучшения церебральной перфузии; оценка рисков церебральной эмболии, связанной с этим вмешательством, остается актуальной темой исследований. Цель исследования – выявить предикторы образования церебральной эмболии, связанной с каротидной ангиопластикой со стентированием (КАС). Материал и методы. В проспективное поисковое исследование были последовательно включены находившиеся на лечении в ФГБНУ «Научный центр неврологии» (Москва) 46 больных (возраст от 44 лет до 81 года, медиана – 65 лет) с атеросклеротическим стенозом внутренней сонной артерии, которым была выполнена КАС. В исследование не включались пациенты с рестенозом, инсультом с тяжелой инвалидизацией, наличием противопоказаний к приему антиагрегантов, статинов и проведению МРТ-исследования. Всем пациентам было проведено предоперационное ультразвуковое (УЗ) исследование и послеоперационное гистологическое исследование частиц в противоэмболических защитных устройствах каротидных стентов. Состояние вещества головного мозга до и через 24 ч после КАС оценивалось с помощью диффузионно-взвешенной МРТ. Для выявления предикторов развития церебральной эмболии клинические характеристики пациентов вместе с УЗ- и морфологическими данными были исследованы в многофакторном статистическом анализе. Результаты. Предоперационный УЗ-сигнал от атеросклеротической бляшки высокой (оценочно выше 35 дБ) интенсивности ассоциировался с плотным веществом (в защитном устройстве) вида «фиброз с кальцинозом» и «кальцификат» и с высокой вероятностью (80%; 95% доверительный интервал 71–85%) прогнозировал интраоперационную эмболизацию сосудов мозга с появлением новых очагов ишемии (НОИ). При невысокой же (не выше 35 дБ) интенсивности предоперационного УЗ-сигнала вероятность образования НОИ была статистически значимо ниже (50%). Заключение. Интенсивность УЗ-сигнала и плотность вещества в защитном устройстве связаны прямой зависимостью. Высокая интенсивность предоперационного УЗ-сигнала (оценочно выше 35 дБ) является неблагоприятным предиктором образования (с вероятностью около 80%) НОИ, связанных с КАС.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>каротидный стеноз</kwd><kwd>стентирование сонной артерии</kwd><kwd>атеросклероз</kwd><kwd>церебральная эмболия</kwd><kwd>прогноз эмболии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carotid stenosis</kwd><kwd>stenting of the carotid artery</kwd><kwd>atherosclerosis</kwd><kwd>cerebral embolism</kwd><kwd>embolism prognosis</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">Алекян БГ, Покровский АВ, Карапетян НГ, Ревишвили АШ.
