Существует несколько теорий корреляции между мальформацией Киари и сирингомиелией, однако точный механизм развития сирингомиелии остается предметом для дискуссии.</p><p>В статье описан клинический случай лечения ребенка с аномалией Киари I типа и сирингомиелией шейных и грудных сегментов спинного мозга, у которого после проведенной декомпрессии задней черепной ямки «полного объема» в раннем послеоперационном периоде возникло прогрессирование сирингомиелии с развитием грубого неврологического дефицита. Учитывая отсутствие стандартных подходов в лечении таких послеоперационных осложнений, принято решение о выжидательной тактике ведения пациента. С двадцатых суток послеоперационного периода у пациента отмечен полный регресс неврологического дефицита и положительная магнитно-резонансная томография (МРТ) динамика сирингомиелии.</p><p>Представленный клинический случай поднимает не только вопросы патофизиологии прогрессирования сирингомиелии после выполнения декомпрессии задней черепной ямки «полного объема», но и определение тактики ведения пациента в случае осложнённого послеоперационного течения заболевания. Интерес представленного клинического случая заключается в том, что описано редко встречающееся усугубление сирингомиелии с нарастанием неврологической симптоматики в раннем послеоперационном периоде после выполнения декомпрессии задней черепной ямки «полного объема».</p><p>Основываясь на данных нашего наблюдения, выжидательная тактика ведения пациента, несмотря на прогрессирование сирингомиелии с усугублением неврологического дефицита, после декомпрессии задней черепной ямки позволила добиться благополучного отдаленного результата течения заболевания, связанного с аномалией Киари I типа.</p></abstract><trans-abstract xml:lang="en"><p>Today, an Arnold-Chiari malformation is defined as a developmental pathology of the craniovertebral junction manifested by a discrepancy between the volume and contents of the posterior cranial fossa, which in turn leads to compression of neurological structures and changes in the cerebrospinal fluid circulation. There are several theories of the correlation between Chiari malformation and syringomyelia, but the exact mechanism of syringomyelia development remains unclear.</p><p>This article describes a clinical case of treatment of a child with Chiari I malformation and syringomyelia within the cervical and thoracic segments of the spinal cord; after complete posterior fossa decompression, syringomyelia progressed in the early postoperative period with the development of a severe neurological deficiency. Since there is no standard treatment of such postoperative complications, a decision was made on the expectant management of the patient. From the twentieth day of the postoperative period, the patient showed complete regression of the neurological deficiency and positive MRI dynamics of syringomyelia.</p><p>The presented clinical case raises such issues as not only the pathophysiology of syringomyelia progression after complete posterior fossa decompression, but also the determination of patient management tactics in case of a complicated postoperative course of the disease.</p><p>The presented clinical case is of interest due to the rarely described aggravation of syringomyelia with enhancing neurological symptoms in the early postoperative period after complete posterior fossa decompression. Our observation suggests that the expectant management of the patient, despite syringomyelia progression with neurological deficiency aggravation after posterior fossa decompression, allowed a favorable long-term outcome of Chiari I malformation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прогрессирование сирингомиелии</kwd><kwd>аномалия Киари I</kwd><kwd>аномалия краниовертебрального перехода</kwd><kwd>декомпрессия задней черепной ямки.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>syringomyelia progression</kwd><kwd>Chiari I malformation</kwd><kwd>craniovertebral junction anomaly</kwd><kwd>posterior fossa decompression</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">Tubbs RS, Beckman J, Naftel RP, Chern JJ, Wellons JC, Rozzelle CJ, et al.
