При этом аневризмы могут возникать на любых церебральных артериях, в том числе на аномальных. В клиническом наблюдении представлен случай разрыва аневризмы, расположенной в дистальном сегменте гипертрофированной медиальной лобно-базальной артерии. Сложность клинического случая состояла в том, что у пациента также имелась аневризма средней мозговой артерии, разрыв которой по данным заключения из первичного сосудистого центра явился причиной субарахноидального кровоизлияния, при этом аневризма лобно-базальной артерии выявлена не была. Только после перевода пациента в региональный сосудистый центр и прицельного пересмотра ангиограмм при подготовке пациента к операции выявлена дистальная аневризма лобно-базальной артерии, которая по данным интраоперационной картины явилась причиной кровоизлияния.</p></abstract><trans-abstract xml:lang="en"><p>Cerebral aneurysms are most often located on the proximal segments of the arteries of the circle of Willis, with some predisposition towards the anterior communicating artery. However, aneurysms can develop on any cerebral arteries including abnormal ones. In this clinical observation, a case of rupture of an aneurysm located in the distal segment of the hypertrophied medial frontobasal artery is presented. The case was complicated by the presence of an aneurysm on the middle cerebral artery, the rupture of which, according to the conclusion from the primary vascular center, caused subarachnoid hemorrhage, while an aneurysm of the frontobasal artery was not detected. It was only after the patient was transferred to a regional vascular center and a targeted review of angiograms during the preparation of the patient for surgery that a distal aneurysm of the frontobasal artery was detected, which, according to the intraoperative picture, was the cause of the hemorrhage.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аневризма</kwd><kwd>субарахноидальное кровоизлияние</kwd><kwd>передняя мозговая артерия</kwd><kwd>медиальная лобно-базальная артерия</kwd><kwd>глазнично-лобная артерия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aneurysm</kwd><kwd>subarachnoid hemorrhage</kwd><kwd>anterior cerebral artery</kwd><kwd>medial frontobasal artery</kwd><kwd>orbitofrontal artery</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">Крылов В.В., Дашьян В.Г., Шатохин Т.А. и др.
