В современных исследованиях акцент делается на анализ гемодинамических изменений в печени при диффузных заболеваниях, а также на роль механизмов, повышающих артериальную перфузию при снижении портального кровотока. Диффузные заболевания печени со временем приводят к фиброзу и риску развития цирроза, и инвазивная биопсия остается единственным точным методом для стадирования у пациентов данной группы. Неинвазивные диагностические подходы, включая эластографию и шкалу оценки Child–Pugh, обеспечивают эффективную оценку степени тяжести цирроза печени.  Перфузионная КТ (ПКТ) позволяет определить функциональное состояние гепатоцитов и определить их микроциркуляцию. Метод безопасен, обладает высокой разрешающей способностью и предоставляет комплексные параметры перфузии печени. Широкодетекторные компьютерные томографы позволяют нивелировать различные артефакты, получить перфузионные изображения печени за один оборот рентгеновской трубки и расширяют диагностические возможности данной методики.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: оценка диагностической эффективности объемной ПКТ в определении степени выраженности гемодинамических нарушений у пациентов с портальной гипертензией (ПГ) с учетом уровня блока портального кровообращения.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В проспективном исследовании приняло участие 110 пациентов, разделенных на 4 группы: 63 пациента с циррозом печени (ЦП) (блок на уровне внутрипеченочного постсинусоидального кровообращения); 10 пациентов с фиброзом печени (ФП) (блок на уровне внутрипеченочного пресинусоидального кровообращения); 13 пациентов с ПГ внепеченочной этиологии (блок на уровне подпеченочного кровообращения), 24 пациента контрольной группы – доноры фрагмента печени. В рамках исследования оценивались показатели перфузии печени, такие как артериальная перфузия (AP), портальная перфузия (PP) и печеночно-перфузионный индекс (HPI).</p></sec><sec><title>Результаты</title><p>Результаты. Наиболее выраженные отклонения перфузии печени верифицированы при подпеченочном блоке (ВПГ) с существенным ростом печеночного индекса (35,6 ± 1,5%; p &lt; 0,001). При ЦП с постсинусоидальным блоком отмечено достоверное снижение портальной фракции (указать значения ПФ), компенсаторное увеличение артериального кровотока до 41,4 ± 0,7 мл/100 мл/мин и соответственно более высокий рост печеночного индекса (23,8 ± 0,4%; p &lt; 0,001). Парадоксальные изменения показателей перфузии с формированием гиперкинетического типа кровообращения и увеличением портального кровотока относительно нормативных значений до 169,4 ± 5,0 мл/100 мл/мин (p &lt; 0,01) получены при ФП.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты подтверждают диагностическую эффективность объемной КТ-перфузии и ее значимость в оценке, прогнозировании выраженности гемодинамических нарушений у пациентов с учетом уровня блока портального кровообращения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Modern studies focus on the analysis of hemodynamic changes in the liver in diffuse pathologies, as well as the role of mechanisms that increase arterial perfusion with a decrease in portal blood flow. Diffuse liver diseases eventually lead to fibrosis and the risk of cirrhosis, but invasive biopsy remains the only accurate method for staging. Non-invasive methods such as elastography and the Child–Pugh scale help assess the severity of liver cirrhosis. Perfusion CT (PCT) allows you to determine the functional state of hepatocytes and determine their microcirculation. The method is safe, has a high resolution and provides complex parameters of liver perfusion. Wide-detector CT allows you to level out various artifacts, obtain perfusion images of the liver in a single scan and expand the diagnostic capabilities of this technique.</p></sec><sec><title>The aim</title><p>The aim: to evaluate the diagnostic effectiveness of volumetric perfusion CT in determining the severity of hemodynamic disorders in patients with portal hypertension (PH), taking into account the level of blockage of the portal circulation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods.The prospective study involved 110 patients divided into four groups: 63 patients with liver cirrhosis (LC) (block at the level of the intrahepatic postsinusoidal circulation); 10 patients with liver fibrosis (LF) (block at the level of intrahepatic presinusoidal circulation); 13 patients with PH of extrahepatic etiology (block at the level of the subhepatic circulation), 24 patients in the control group, donors of the liver fragment. The study assessed liver perfusion parameters such as arterial perfusion (AP), portal perfusion (PP) and hepatic perfusion index (HPI).</p></sec><sec><title>Results</title><p>Results. The most pronounced deviations in liver perfusion were verified in subhepatic block (SHB), with a significant increase in the liver index (35.6 ± 1.5%; p &lt; 0.001). In cirrhosis with postsinusoidal block, there was a significant decrease in the portal fraction, a compensatory increase in arterial blood flow to 41.4 ± 0.7 ml/100 ml/min and, accordingly, a higher increase in the liver index (23.8 ± 0.4%; p &lt; 0.001). Paradoxical changes in perfusion parameters with the formation of a hyperkinetic type of blood circulation and an increase in portal blood flow relative to normative values up to 169.4 ± 5.0 ml/100 ml/min (p &lt; 0.01) were obtained in AF.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results confirm the diagnostic effectiveness of volumetric CT perfusion and its significance in assessing and predicting the severity of hemodynamic disorders in patients, taking into account the level of blockage of the portal circulation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>перфузионная КТ</kwd><kwd>цирроз печени</kwd><kwd>фиброз печени</kwd><kwd>портальная гипертензия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>perfusion CT</kwd><kwd>liver cirrhosis</kwd><kwd>liver fibrosis</kwd><kwd>portal hypertension</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">Li Y., Pan Q., Zhao H.
