However, these shunts can promote the development of some complications: total discharge of the portal blood into the inferior vena cava can also cause some complications such as minimal manifestations of pulmonary arterial hypertension, decreased portal perfusion of the liver (PPP), hyperammonemia, and latent hepatic encephalopathy. An alternative to SRA is distal splenorenal anastomosis (DSRA), which is a selective PSS and which maintains PPL, thus reducing a risk of developing the listed complications. However, in practice, its use is limited due to high frequency of anastomotic thrombosis and ascites/chyloperitoneum at the early postoperative period.</p> <p><bold>AIM</bold>: Prevention of all the above-mentioned complications of artificial PSS continues to be a pressing issue in modern paediatric surgery. However, we have proposed a new curative option — reconstruction of the SRA into a DSRA, which reduced the risk of all mentioned complications, thereby improving the quality of patients’ life.</p> <p><bold>METHODS</bold>: From February 2020 to May 2024, 54 children were operated on with this type of surgery. The goal was to change the direction of the mesenteric venous blood flow (in SRA it is directed towards the anastomosis) towards the liver by clipping/ligating the splenic vein to the right of the anastomosis. All children, before and after the anastomosis reconstruction, underwent a comprehensive examination in full or in part, including a biochemical blood test, magnetic resonance imaging of the brain, echocardiography, ultrasound of the abdominal organs, angiography, esophagogastroduodenoscopy, neuropsychological examination (36 patients were followed-up at late stages after the surgery).</p> <p><bold>RESULTS</bold>: On a comparative findings, improvement of cognitive functions was seen in 60% of children, relief of hyperammonemia — in 71%, relief of signs of manganese salts accumulation of in the central nervous system — in 43%, improvement of hemodynamic parameters according to echocardiography — in 75%, improvement of PPL — in 78%. No patients had anastomotic thrombosis. Ascites/chyloperitoneum was registered only in 5% of cases.</p> <p><bold>CONCLUSION</bold>: The developed surgical technique is a promising one for it prevents/treats complications of artificial PSS, such as pulmonary arterial hypertension, decreased PPL, hepatic encephalopathy, anastomotic thrombosis and ascites.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold>. На сегодняшний день у детей с портальной гипертензией наиболее эффективным методом лечения являются операции сосудистого шунтирования. По ряду причин на практике преимущественно используются спленоренальные анастомозы (СРА), которые являются тотальными портосистемными шунтами (ПСШ). Однако при них тотальный сброс портальной крови в нижнюю полую вену приводит к таким осложнениям, как минимальные проявления лёгочной артериальной гипертензии, уменьшение портальной перфузии печени (ППП), гипераммониемия и скрытая печёночная энцефалопатия. Альтернатива СРА — дистальный СРА (ДСРА), который является селективным ПСШ и поддерживает ППП, снижая риск развития перечисленных осложнений. Однако на практике его применение ограничено из-за высокой частоты тромбоза анастомоза, асцита или хилоперитонеума в раннем послеоперационном периоде.</p> <p><bold>Цель</bold>. Профилактика всех вышеупомянутых осложнений искусственных ПСШ продолжает оставаться актуальной проблемой в современной детской хирургии. Однако нами предложен новый метод лечения — реконструкция СРА в ДСРА — позволивший снизить риск осложнений и улучшить качество жизни пациентов.</p> <p><bold>Методы</bold>. С февраля 2020 по май 2024 года данная операция выполнена 54 пациентам. Вмешательство заключалось в смене направления мезентериального венозного кровотока в сторону печени (при СРА он направлен к анастомозу) путём клипирования или лигирования селезёночной вены справа от анастомоза. Всем детям до и после реконструкции анастомоза полностью или частично проводилось комплексное обследование, включающее биохимический анализ крови, магнитно-резонансную томографию головного мозга, эхокардиографию и ультразвуковое исследование органов брюшной полости, ангиографию, эзофагогастродуоденоскопию, нейропсихологическое обследование (в поздние сроки после операции контрольное обследование прошли 36 пациентов).</p> <p><bold>Результаты</bold>. При сравнительном анализе улучшение когнитивных функций отмечалось у 60% детей, купирование гипераммониемии — у 71%, купирование признаков накопления солей марганца в центральной нервной системе — у 43%, улучшение показателей гемодинамики по данным эхокардиоскопии — у 75%, улучшение ППП — у 78%. Тромбоза анастомоза не наблюдалось ни у кого. Асцит или хилоперитонеум отмечались лишь в 5% случаев.</p> <p><bold>Заключение</bold>. Разработанная операция является многообещающим методом профилактики и лечения таких осложнений искусственных ПСШ, как лёгочная артериальная гипертензия, снижение ППП, печёночная энцефалопатия, тромбоз анастомоза и асцит.</p></trans-abstract><kwd-group xml:lang="en"><kwd>children</kwd><kwd>portal hypertension</kwd><kwd>splenorenal anastomoses</kwd><kwd>anastomotic reconstruction</kwd><kwd>portal liver perfusion</kwd><kwd>hyperammonemia</kwd><kwd>hepatic encephalopathy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>портальная гипертензия</kwd><kwd>спленоренальные анастомозы</kwd><kwd>реконструкция анастомоза</kwd><kwd>портальная перфузия печени</kwd><kwd>гипераммониемия</kwd><kwd>печёночная энцефалопатия</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российское общество симуляционного обучения в медицине</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Society for Simulation Education in Medicine</institution></institution-wrap></funding-source><award-id>2412–37/22</award-id></award-group><funding-statement xml:lang="ru">Исследование проведено при поддержке гранта («Хирургические методы профилактики жизнеугрожающих осложнений у детей»; соглашение 2412-37/22, дата: 30.03.2022г.) и при технической помощи группы компаний «Р-Фарм»</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Patel N, Grieve A, Hiddema J, et al.
