However, nowadays it tends to be regarded mainly as a salvage procedure when standard shunting or endoscopic ventriculostomy is not feasible.</p><sec><title>Case report</title><p>Case report. A 5-year-old boy with obstructive hydrocephalus secondary to a cystic midbrain tumor underwent tumor resection combined with Torkildsen ventriculocisternostomy. Postoperatively, adjuvant radiotherapy was administered, resulting in long-term disease stabilization. At the age of 37 years, 32–33 years after surgery, he developed dysphagia, respiratory disturbances, cervico-occipital pain, and sensory impairment in the upper limbs. Magnetic resonance imaging demonstrated migration of the distal catheter tip with penetration into the upper cervical spinal cord segments and formation of a focal myelopathic lesion. A suboccipital craniotomy was performed; the migrated catheter segment was removed, the system was shortened, and the distal end was reimplanted into the cisterna magna with fixation to the dura mater. Complete regression of neurological deficits was achieved, with a favorable 10-year follow-up.</p></sec><sec><title>Discussion</title><p>Discussion. We report a rare delayed case of myelopathy caused by migration of the cisternal catheter tip more than 30 years after Torkildsen ventriculocisternostomy. This observation highlights the need for lifelong surveillance of patients who have undergone such procedures, strict adherence to surgical technique (appropriate catheter length selection and secure fixation), and timely surgical revision at the earliest signs of brainstem dysfunction or involvement of the upper cervical spinal cord.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Вентрикулоцистерностомия по Торкильдсену исторически была одним из основных методов лечения окклюзионной гидроцефалии, но сейчас рассматривается преимущественно как резервная процедура при ограниченных возможностях для стандартного шунтирования или эндоскопической вентрикулостомии.</p><sec><title>Описание случая</title><p>Описание случая. У мальчика 5 лет с окклюзионной гидроцефалией на фоне кистозной опухоли среднего мозга выполнено ее удаление с дополнением вентрикулоцистерностомией по Торкильдсену. После операции проведена дистанционная гамма-терапия, достигнута длительная стабилизация. Через 32–33 года, в возрасте 37 лет, возникли дисфагия, дыхательные нарушения, боли в шейно-затылочной области и расстройства чувствительности в руках. Магнитно-резонансная томография выявила миграцию дистального конца катетера с инвазией в верхние шейные сегменты спинного мозга и формированием очага миелопатии. Выполнена субокципитальная краниотомия, мигрировавший сегмент катетера удален, система укорочена, дистальный конец реимплантирован в большую затылочную цистерну с фиксацией к твердой мозговой оболочке. Отмечен полный регресс дефицита и благоприятный 10-летний катамнез.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Представлен редкий отсроченный случай миелопатии, обусловленной миграцией цистернального конца катетера более чем через 30 лет после вентрикулоцистерностомии по Торкильдсену. Наблюдение подчеркивает необходимость пожизненного мониторинга пациентов с такими вмешательствами, строгого соблюдения техники (подбор длины катетера, надежная фиксация) и своевременной хирургической коррекции при первых признаках стволовой симптоматики и поражения верхних шейных сегментов спинного мозга.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>опухоли ствола головного мозга</kwd><kwd>окклюзионная гидроцефалия</kwd><kwd>вентрикулоцистерностомия по Торкильдсену</kwd><kwd>реимплантация</kwd><kwd>катамнестическое наблюдение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>brainstem tumors</kwd><kwd>occlusive hydrocephalus</kwd><kwd>Torkildsen ventriculocisternostomy</kwd><kwd>reimplantation</kwd><kwd>long-term follow-up</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки (собственные ресурсы)</funding-statement><funding-statement xml:lang="en">The study was unfunded (own resources)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zinn P.O., Bozinov O., Burkhardt J.K., et al.
