To study this problem is an important step in making an adequate choice of treatment modality in children with PH regarding the risk of HE development in future.</p> <p><bold>METHODS</bold>: This paper analyzes the results of studies of ammonia content in venous blood in 173 children, of whom 153 had PH (most had undergone vascular bypass surgery).</p> <p><bold>RESULTS</bold>: The analysis performed has shown that the risk of hyperammonemia in non-operated patients with PH is low, but it increases after certain vascular bypass surgeries on the portal system vessels. To the least extent, this applies to the physiological mesoprotal shunt (MPS) and selective distal splenorenal anastomosis (DSRA), and to the greatest extent — to total portosystemic shunts: splenorenal anastomoses (SRA) (side-to-side splenorenal anastomosis, splenosuprarenal anastomoses) and mesocaval shunt (MCS).</p> <p><bold>CONCLUSION</bold>: Our findings have confirm advantages (low risk of hyperammonemia in childhood) of the mesoportal shunt and distal splenorenal anastomosis compared to splenorenal anastomoses and mesocaval H-shunt. At the same time, the study proves the effectiveness of reconstruction of the splenorenal anastomosis into a distal splenorenal anastomosis in reducing the level of ammonia in the blood (this operation was developed at the N.F. Filatov Children's City Clinical Hospital).</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold>. Развитие гипераммониемии и последующей печёночной энцефалопатии после операций портосистемного шунтирования (ПСШ) у детей с портальной гипертензией (ПГ) продолжает оставаться актуальной проблемой в современной детской хирургии.</p> <p><bold>Цель</bold>. В настоящее время крайне мало данных о распространённости гипераммониемии после различных операций сосудистого шунтирования в больших группах пациентов с ПГ. Изучение этой проблемы может помочь в выборе метода лечения детей с ПГ с учётом риска развития печёночной энцефалопатии в будущем.</p> <p><bold>Методы</bold>. В работе проанализированы результаты исследований содержания аммиака в венозной крови у 173 детей, из которых 153 с ПГ (у большинства пациентов выполнена операция сосудистого шунтирования).</p> <p><bold>Результаты</bold>. Согласно данным анализа, у неоперированных пациентов с ПГ риск гипераммониемии мал, однако он повышается после применения определённых операций сосудистого шунтирования на сосудах портальной системы. В наименьшей степени это распространяется на физиологический мезопортальный шунт и селективный дистальный спленоренальный анастомоз, а в наибольшей степени — на тотальные портосистемные шунты: спленоренальные анастомозы (спленоренальный анастомоз «бок-в-бок», спленосупраренальные анастомозы) и мезокавальный Н-шунт.</p> <p><bold>Заключение</bold>. Наши данные подтверждают преимущества (низкий риск развития гипераммониемии в детском возрасте) мезопортального шунта и дистального спленоренального анастомоза по сравнению со спленоренальными анастомозами и мезокавальным Н-шунтом. Одновременно исследование доказывает эффективность реконструкции спленоренального анастомоза в дистальный спленоренальный анастомоз в снижении уровня аммиака в крови (данная операция разработана в ДГКБ им. Н.Ф. Филатова).</p></trans-abstract><kwd-group xml:lang="en"><kwd>hyperammonemia</kwd><kwd>portal hypertension</kwd><kwd>vascular bypass operations</kwd><kwd>children</kwd><kwd>splenorenal anastomoses</kwd><kwd>anastomotic reconstruction</kwd><kwd>mesoportal shunt</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гипераммониемия</kwd><kwd>портальная гипертензия</kwd><kwd>операции сосудистого шунтирования</kwd><kwd>дети</kwd><kwd>спленоренальные анастомозы</kwd><kwd>реконструкция анастомоза</kwd><kwd>мезопортальный шунт</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство г.
