Определить значение эластографии печени и селезенки в диагностике внепеченочной обструкции воротной вены - «нецирротического» тромбоза воротной вены (ТВВ). Материал и методы. В группу исследования были включены 19 пациентов в возрасте от 21 года до 76 лет с наличием ТВВ, установленным на основании результатов мультиспиральной компьютерной томографической ангиографии, у которых отсутствовали опухоли печени / панкреатобилиарной зоны и цирроз печени (ЦП). Группу сравнения составили 23 больных HCV-ЦП класса А по Child-Pugh. В обеих группах оценивали анамнез портальной гипертензии; уровень тромбоцитов, альбумина, аланиновой и аспарагиновой аминотрансфераз; протромбиновый тест по международному нормализованному отношению; размер варикозно-расширенных вен пищевода (ВРВП); продольный размер селезенки по результатам ультразвукового исследования (УЗИ); плотность печени и селезенки. Результаты. Группа пациентов с «нецирротическим» ТВВ характеризовалась наличием клинически значимой портальной гипертензии (ВРВП, спленомегалия и гиперспленизм). Причинами развития ТВВ служили системные факторы: миелопролиферативные заболевания, мутация G20210A в гене протромбина, и локальные факторы: осложнения после оперативных вмешательств на панкреатобилиарной системе, омфалит и пупочный сепсис в раннем неонатальном периоде. Девять пациентов в течение 1-2 лет до поступления в клинику находились под наблюдением в различных медицинских учреждениях с диагнозом «криптогенный цирроз печени». Показатели плотности печени у всех пациентов составили от 2,8 до 11,5 кПа. Степень выраженности ВРВП имела тенденцию к нарастанию с увеличением показателей плотности селезенки. При сравнении групп больных с «нецирротическим» ТВВ и с HCV-ЦП класса А по Child-Pugh выявлены статистически значимые различия между ними по уровню аминотрансфераз, которые были повышены в 1,5-2 раза у больных ЦП (р&lt;0,0001). По показателям белоксинтетической функции печени и выраженности тромбоцитопении группы не различались. ВРВП статистически значимо чаще выявляли у больных с «нецирротическим» ТВВ, чем в группе сравнения (р=0,028). Установлены статистически значимые различия между группами по показателям плотности печени: у пациентов с «нецирротическим» ТВВ медиана плотности печени составила 5,6 кПа, у больных ЦП - 20,6 кПа (p&lt;0,0001). Выводы. Проведение эластографии печени целесообразно у больных с впервые выявленной портальной гипертензией и ТВВ. Для дифференциального диагноза между ТВВ, обусловленным ЦП и «нецирротическими» причинами, можно использовать точку разделения 11,5 кПа. Для построения многофакторной модели необходимо дальнейшее проведение исследований с большим числом пациентов. Диагностическое значение исследования плотности селезенки как метода неинвазивной оценки выраженности портальной гипертензии у больных с «нецирротическим» ТВВ подтверждают опубликованные данные. Для определения точки разделения с целью прогнозирования развития ВРВП и кровотечений у больных этой категории требуются большее число пациентов и учет «вмешивающихся» факторов.</p></abstract><trans-abstract xml:lang="en"><p>Aim of investigation. To estimate diagnostic value of liver and spleen elastography in patients with extrahepatic portal vein obstruction - non-cirrhotic portal vein thrombosis (PVT). Material and methods. The study group: 19 patients (Age 21-76 years) with PVT diagnosed by multispiral computed angiography without liver/pancreatobiliary tumors and/or liver cirrhosis (LC). The comparison group included 23 patients with LC Child-Pugh class A. Past history of portal hypertension, platelet count, serum albumin level, alanine and aspartate aminotransferase level; prothrombin according to international normalization ratio; grade of esophageal varices (EV); spleen longitudinal size according to abdominal ultrasound, liver and spleen stiffness were evaluated in both groups. Results. The group of patients with non-cirrhotic PVT was characterized by presence of clinically significant portal hypertension (EV, splenomegaly and hypersplenism). Following causes for PVT were established: systemic factors - myeloproliferative diseases, G20210A prothrombin gene mutation, and local factors: complications after pancreatobiliary surgery, omphalitis and neonatal umbilical sepsis. Nine patients, 1 to 2 years prior to hospitalization, were previously misclassified as «cryptogenic liver cirrhosis» in various medical institutions. Liver stiffness in PVT group was 2,8-11,5 kPa. The grade of EV tended to increase along with progression of the spleen stiffness. Statistically significant difference in serum aminotransferases levels in non-cirrhotic PVT vs Child-Pugh class A HCV-LC was observed: enzyme levels were 1,5-2 fold higher in LC (р&lt;0,0001). No differences in the protein-synthetic liver function and severity of thrombocytopenia were found. Prevalence of EV was higher in non-cirrhotic group (р=0,028).) Statistically significant differences between groups in a liver stiffness were revealed: in non-cirrhotic PVT patients the median liver stiffness was 5,6 kPa, in LC patients it was 20,6 kPa, (p&lt;0,0001). Conclusions. Liver elastography is rational in patients with primary diagnosed portal hypertension and PVT. For the differential diagnosis between LC-related PVT and the non-cirrhotic PVT the cut-off value of 11,5 kPa can be applied. Plotting of multifactorial model requires further studies with larger number of patients. Diagnostic value of spleen stiffness measurement as method for noninvasive diagnostic of degree of portal hypertension in non-cirrhotic PVT has been confirmed by the published data. Estimation of a cut-off value to predict EV development and EV bleeding in these patients requires larger number of patients and considering confounding factors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эластография</kwd><kwd>печень</kwd><kwd>селезенка</kwd><kwd>диагностика</kwd><kwd>внепеченочная обструкция воротной вены</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">de Franchis R. on behalf of the Baveno VI Faculty, Expanding consensus in portal hypertension.
