Аневризмы задней нижней мозжечковой артерии - достаточно редкая сосудистая патология как среди интракраниальных аневризм, так и находящихся в вертебробазилярном бассейне. В связи с близостью каудальной группы нервов микрохирургическое лечение может сопровождаться развитием бульбарных нарушений, поэтому методом выбора применительно к аневризмам устья задней нижней мозжечковой артерии служит эндоваскулярная окклюзия. Однако анатомические особенности аневризмы в вертебробазилярном бассейне и их индивидуальные характеристики нередко затрудняют антеградную катетеризацию артерии. В таких случаях должны применяться альтернативные методы, один из которых - трансциркулярный доступ через заднюю соединительную артерию.</p><p>Цель исследования - представить результат эндоваскулярного лечения пациентки со сложной аневризмой задней нижней мозжечковой артерии, выполненного в условиях стент-ассистенции через трансциркулярный доступ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В статье проведен анализ результатов лечения пациентки в ФГБУ «Федеральный центр нейрохирургии» Минздрава России (Новосибирск). Оперативное вмешательство заключалось в эндоваскулярной окклюзии аневризмы устья правой задней нижней мозжечковой артерии со стент-ассистенцией. Особенностью данного случая служил острый угол отхождения задней нижней мозжечковой артерии от позвоночной артерии, что существенно затрудняло прямую эндоваскулярную катетеризацию аневризмы и повышало риски интраоперационных осложнений. В качестве доступа выбран трансциркулярный подход через заднюю соединительную артерию. Через 6 мес после выписки проведено контрольное обследование пациентки.</p></sec><sec><title>Результаты</title><p>Результаты. После вмешательства отмечены отличные результаты: клинический (отсутствие нового неврологического дефицита) и ангиографический (полная облитерация по классификации степени окклюзии аневризмы Raymond-Roy Occlusion Classification - Raymond Roy I) как на момент выписки пациентки, так и во время динамического наблюдения по результатам контрольных ангиограмм.</p></sec><sec><title>Заключение</title><p>Заключение. Использование трансциркулярного эндоваскулярного доступа к проксимальной аневризме задней нижней мозжечковой артерии позволило получить хороший результат хирургического лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Aneurysms of the posterior inferior cerebellar artery are a rare vascular pathology among both intracranial aneurysms and aneurysms of the vertebrobasilar territory. Due to the proximity of the caudal nerves, microsurgical treatment may be accompanied by the development of bulbar disorders, so endovascular occlusion is the method of choice for aneurysms of origin of the posterior inferior cerebellar artery. However, anatomical features in the vertebrobasilar territory and individual characteristics of the aneurysm often make antegrade catheterization of the artery difficult. In such cases, alternative methods should be used, one of which is transcircular access through the posterior communicating artery.</p></sec><sec><title>Aim</title><p>Aim. To present the result of endovascular treatment of a patient with complex aneurysm of the posterior inferior cerebellar artery, performed with through a transcirculation approach.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The article analyzes the results of the patient's treatment at the Federal Neurosurgical Center (Novosibirsk) of the Ministry of Health of Russia. Surgical intervention consisted of endovascular occlusion of the aneurysm of the right posterior inferior cerebellar artery with stent-assistance. A specific feature of this case was the acute angle of posterior inferior cerebellar artery discharge from the vertebral artery, which significantly hampered the direct endovascular catheterization of the aneurysm and increased the risks of intraoperative complications. A transcirculation approach through the posterior communicating artery was chosen as an access. After discharge, the patient underwent a follow-up examination 6 months later.</p></sec><sec><title>Results</title><p>Results. Excellent clinical and angiographic results (occlusion classification (RROC - Raymond Roy I) were noted both at the time of the patient's discharge and during follow-up based on the results of control angiograms.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of transcirculation endovascular access to the proximal aneurysm of the posterior inferior cerebellar artery made it possible to obtain a good result of surgical treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аневризма задней нижней мозжечковой артерии</kwd><kwd>трансциркулярный доступ</kwd><kwd>эндоваскулярная окклюзия аневризмы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>posterior inferior cerebellar artery aneurysm</kwd><kwd>transcirculation access</kwd><kwd>endovascular aneurysm occlusion</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">Mascitelli J.R., Yaeger K., Wei D. et al.
