Traditional methods of shutting down such aneurysms are not applicable. Treatment tactics remain a subject of debate. The presence of COVID-19 complicates the course of the disease and complicates the routing of the patient to a specialized hospital.</p><sec><title>Description of the case</title><p>Description of the case. A 36-year-old man with COVID-19 developed an ischemic stroke in the territory of the right middle cerebral artery (MСA), clinically manifested by dysarthria and pronounced left-sided hemiparesis. Cerebral angiography (CAG) revealed thrombosis of the parietal branch of the M2 segment of the right MСA with distal filling of the channel from the territory of the left MСA. After 3 months, according to the control CAG, recanalization of the M2 segment of the right MСA and fusiform aneurysm of this segment of the artery were diagnosed. To turn off the aneurysm, an intra-intracranial anastomosis was applied between the upper and lower M2 segments of the right MСA and an extra-intracranial anastomosis between the parietal branch of the right superficial temporal artery and the cortical branch from the territory of the compromised M3 segment of the MСA, the aneurysm was excised. The postoperative period was complicated by reinfection of SARS-CoV-2. After the treatment, the patient was discharged in a satisfactory condition without neurological deficit.</p></sec><sec><title>Discussion</title><p>Discussion. Resection of an aneurysm with revascularization of the distal bed can be considered as the method of choice in patients with distal aneurysms if it is impossible to apply traditional clipping. The presence of COVID-19 infection increases the risk of thrombotic complications, imposes increased requirements on the technique of performing vascular anastomoses.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Значительная часть дистальных церебральных аневризм относится к категории сложных. Традиционные методы выключения таких аневризм неприменимы. Тактика лечения остается предметом дискуссий. Наличие COVID-19 осложняет течение заболевания и усложняет маршрутизацию пациента в специализированный стационар.</p><sec><title>Описание случая</title><p>Описание случая. У мужчины 36 лет на фоне COVID-19 развился ишемический инсульт в бассейне правой средней мозговой артерии (СМА), клинически проявившийся дизартрией и выраженным левосторонним гемипарезом. Церебральная ангиография (ЦАГ) выявила тромбоз теменной ветви М2 сегмента правой СМА с дистальным заполнением русла из бассейна левой СМА. Через 3 месяца по данным контрольной ЦАГ диагностирована реканализация М2 сегмента правой СМА и фузиформная аневризма этого сегмента артерии. С целью выключения аневризмы наложен интра-интракраниальный анастомоз между верхним и нижним М2 сегментами правой СМА и экстра-интракраниальный анастомоз между теменной ветвью правой поверхностной височной артерии и корковой ветвью из бассейна компрометированного М3 сегмента СМА, аневризма иссечена. Послеоперационный период осложнился повторным инфицированием SARS-CoV-2. После проведенного лечения пациент выписан в удовлетворительном состоянии без неврологического дефицита.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Резекция аневризмы с реваскуляризацией дистального русла может рассматриваться как метод выбора у пациентов с дистальными аневризмами при невозможности применить традиционное клипирование. Наличие инфекции COVID-19 увеличивает риск тромботических осложнений, предъявляет повышенные требования к технике выполнения сосудистых анастомозов.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дистальная аневризма СМА</kwd><kwd>экстра-интракраниальное шунтирование</kwd><kwd>интра-интракраниальное шунтирование</kwd><kwd>лечение дистальных церебральных аневризм</kwd><kwd>церебральная ангиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>distal aneurysm of MCA</kwd><kwd>extra-intracranial bypass surgery</kwd><kwd>intra-intracranial bypass surgery</kwd><kwd>treatment of distal cerebral aneurysms</kwd><kwd>сerebral angiography</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">Rodríguez-Hernández A., Zador Z., Rodríguez-Mena R., Lawton M.T.
