В настоящее время в литературе описано множество вариантов патологии развития передней мозговой артерии, включая такие формы, как аплазия, гипоплазия, дупликация, трипликация и иные. Наличие срединной артерии мозолистого тела - редкая патология передней части виллизиева круга, частота ее встречаемости составляет 4,5-14,2 %. Примерно в 81 % случаев срединная артерия мозолистого тела сочетается с трифуркацией передней соединительной артерии. Встречаемость дистальных аневризм передних мозговых артерий составляет от 1,5 до 9,0 % от всех внутричерепных аневризм. Аневризмы срединной артерии мозолистого тела крайне редко упоминаются в литературе, авторам не удалось найти случаи описания дистальных аневризм данной локализации. Следует учитывать, что при проведении лучевой диагностики до одной трети всех случаев срединной артерии мозолистого тела остаются не выявленными. </p><p>Цель работы - представить клинический случай успешного оперативного лечения дистальной аневризмы срединной артерии мозолистого тела у больного К., 39 лет, проведенного с применением операционной нейронавигации.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Описан клинический случай оперативного лечения дистальной аневризмы срединной артерии мозолистого тела у больного К., 39 лет, на базе ГБУЗ «Городская клиническая больница № 1 им. Н.И. Пирогова» Департамента здравоохранения г. Москвы. Пациенту выполнена компьютерная томография головного мозга с контрастированием: только тогда были выявлены признаки мешотчатой аневризмы сегментов A2-3 срединной артерии мозолистого тела. Проведено оперативное лечение: костно-пластическая трепанация черепа (из бифронтальной краниотомии межполушарный доступ справа), микрохирургическое клипирование обнаруженной дистальной мешотчатой аневризмы срединной артерии мозолистого тела с применением нейронавигации. </p></sec><sec><title>Результаты</title><p>Результаты. Проведено хирургическое лечение в объеме клипирования аневризмы. Использование нейронавигации позволило провести минимальную энцефалотомию медиальных отделов лобных долей в проекции колена мозолистого тела. Селективная ангиография сосудов головного мозга (через 10 мес после операции) показала, что положение клипсы удовлетворительное, признаков реканализации аневризмы срединной артерии мозолистого тела не выявлено. </p></sec><sec><title>Выводы</title><p>Выводы. Более глубокое расположение срединной артерии мозолистого тела относительно обеих передних мозговых артерий и отсутствие естественных анатомических ориентиров затрудняют хирургический доступ к дистальным аневризмам срединной артерии мозолистого тела. Применение операционной навигации способствует решению данных проблем: позволяет выполнить минимальную по размеру краниотомию, выбрать корректный вектор доступа и сокращает операционное время.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. There are many variations of the developmental pathology of the anterior communicating artery with such forms as aplasia, hypoplasia, duplication, triplication and etc. The presence of the median artery of the corpus callosum is a rare pathology of the anterior part of the circle of Willis and, according to the literature the frequency is 4,5-14,2 %. About 81 % of cases, the occurrence of the median artery of the corpus callosum is combined with the presence of anterior communicating artery trifurcation. The incidence of distal anterior cerebral artery aneurysms has been estimated to be from 1.5 to 9.0 % of all intracranial aneurysms, while the median artery of the corpus callosum is rarely mentioned in the literature, the author of the article did not find cases of descriptions of distal anterior cerebral artery aneurysms in the PubMed. It should be borne in mind that when conducting radiation diagnostics, up to one third of all cases of the median artery of the corpus callosum remain undetected.</p></sec><sec><title>Aim</title><p>Aim. To present a clinical case of successful surgical treatment of a distal aneurysm of the median artery of the corpus callosum in a patient K., 39 years old, performed using surgical neuronavigation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A case report of the successful surgical management of 39-year-old patient with distal aneurysm of the median artery of the corpus callosum at the Sity Clinical Hospital No. 1 named after N.I. Pirogov of Moscow Healthcare Department. The patient had a saccular aneurysm of A2-3 segments of the median artery of the corpus callosum.</p></sec><sec><title>Results</title><p>Results. A microsurgical clipping of the distal aneurysm of the median artery of the corpus callosum using the right interhemispheric approach through the bifrontal craniotomy with a neuronavigational assistance was performed. The selective angiography of the intracranial arteries (10 mo after the clipping) no detected the signs of recanalization of the aneurysm.</p></sec><sec><title>Conclusion</title><p>Conclusion. The deeper placement of the median artery of the corpus callosum (as compared with the anterior cerebral arteries) and the missing of anatomical landmarks complicates the surgical approach to the distal aneurysms of the median artery of the corpus callosum. The instrumentation of neuronavigation made it possible to perform minimal craniotomy and safe encephalotomy of the medial aspects of the frontal lobes (at site of the genu the corpus callosum) and reduce the operating time.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>передняя мозговая артерия</kwd><kwd>срединная артерия мозолистого тела</kwd><kwd>трифуркация передней соединительной артерии</kwd><kwd>дистальная аневризма передней мозговой артерии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anterior communicating artery</kwd><kwd>median artery of the corpus callosum</kwd><kwd>anterior communicating artery trifurcation</kwd><kwd>distal anterior cerebral artery aneurysm</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">Ogawa A., Suzuki M., Sakurai Y., Yoshimoto T.
