Повышение пульсационного индекса интракраниального венозного кровотока и потока ликвора на уровне большого затылочного отверстия, уменьшение артериовенозной задержки и индекса интракраниального комплаенса свидетельствуют о нарушении характера распределения пульсационной волны и снижении податливости/растяжимости головного мозга на фоне повышенного внутричерепного давления.</p></sec><sec><title>Цель</title><p>Цель. Оценить параметры гемо- и ликвородинамики у пациентов с синдромом идиопатической внутричерепной гипертензии по данным фазо-контрастной МРТ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. На МР-томографе Ingenia 3.0Т (Philips, США) обследованы 18 пациентов с синдромом внутричерепной гипертензии и 20 пациентов группы контроля. Использованы рутинный протокол и методика фазо-контрастной МРТ для оценки количественных показателей гемо- и ликвородинамики. Измерены скоростные показатели потоков крови и ликвора для различных структур (ликворные пространства на уровне водопровода мозга, большого затылочного отверстия и шейной области, артерии, вены, прямой и верхний сагиттальный синусы). Рассчитаны объемы крови и ликвора, пульсационный индекс, артериовенозная задержка, индекс интракраниального комплаенса. Достоверность различий между группами контроля и пациентов оценена с применением U-критерия Манна – Уитни.</p></sec><sec><title>Результаты</title><p>Результаты. В группе пациентов выявлены тенденция к увеличению систолического пика объемной скорости ликвора на уровне большого затылочного отверстия без значимого изменения объема пульсирующего ликвора, достоверное увеличение пульсационного индекса ликвора на шейном уровне на 11,88% (p&lt;0,05). Определены тенденция к увеличению объема венозной крови на интракраниальном уровне, а также достоверное увеличение пульсационного индекса на уровне прямого и верхнего сагиттального синусов в 1,3 раза (p&gt;&lt;0,01 и p&gt;&lt;0,05 соответственно). На интракраниальном уровне отмечены сокращение времени артериовенозной задержки в 1,9 раза (p&gt;&lt;0,05) и достоверное уменьшение индекса интракраниального комплаенса в 1,2 раза (p&gt;&lt;0,05). Заключение Оценены показатели гемо- и ликвородинамики у пациентов с синдромом идиопатической внутричерепной гипертензии. В группе пациентов выявлено нарушение параметров ликвородинамики и характера распространения пульсовой волны в интракраниальных отделах. Изменения могут свидетельствовать о снижении податливости/увеличении жесткости мозговой ткани на фоне повышения внутричерепного давления и вероятного диффузного застоя интерстициальной жидкости.

An increase in the pulsatility index of intracranial venous blood flow and cerebrospinal fluid flow at the foramen magnum level, and a decrease in arteriovenous delay and an intracranial compliance index indicate disturbances in the pulse wave distribution, and a decrease in compliance/extensibility of the brain due to increased intracranial pressure.</p></sec><sec><title>Aim</title><p>Aim. To assess the parameters of hemodynamics and cerebrospinal fluid dynamics in patients with idiopathic intracranial hypertension syndrome according to phase-contrast MRI.</p></sec><sec><title>Methods</title><p>Methods. The study included 18 patients with idiopathic intracranial hypertension syndrome and 20 controls, all patient were examined using the Ingenia 3,0T MRI scanner. The analysis was performed using phase-contrast MRI to assess quantitative parameters of hemodynamics and cerebrospinal fluid (CSF) dynamics in 14 different structures. The blood and CSF volumes, pulsatility index (PI), arterio-venous delay, and intracranial compliance index were calculated. The Mann-Whitney U-test reliability was used to assess the differences between the controls and patients.</p></sec><sec><title>Results</title><p>Results. The group of patients had an increased CSF systolic peak at the foramen magnum without significant changes in CSF volume, and significantly increased CSF PI at the cervical level by 11.88% (p&lt;0,05). There was a tendency toward an increase in the intracranial venous blood volume, as well as a tendency toward significant increase in PI at the straight and superior sagittal sinuses by 1,3 times (p&gt;&lt;0,01, p&gt;&lt;0,05). Moreover, there was a reduction of intracranial arterio-venous delay by 1,9 times (p&gt;&lt;0,05), and a significant decrease in the intracranial compliance index by 1,2 times (p&gt;&lt;0,05). Conclusion We have assessed the parameters of hemodynamics and CSF dynamics in patients with idiopathic intracranial hypertension and revealed disturbances in CSF dynamics and pulse wave propagation in the intracranial regions. Such changes may indicate a decrease in compliance/increase in stiffness of the brain tissue due to an increase in intracranial pressure and a possible diffuse stagnation of interstitial fluid.
