Перенесший паллиативную резекцию тонкой кишки пациент готовился к проведению первого сеанса трансартериальной химиоэмболизации (ТАХЭ) печени, когда по данным УЗИ и МРТ в брюшной полости была обнаружена свободная жидкость. Все наиболее вероятные причины асцита (отсевы опухоли по брюшине, правожелудочковая сердечная недостаточность как проявление «карциноидного сердца», портальная гипертензия компрессионной природы вследствие сдавления ветвей воротной вены опухолевыми узлами или эластического фиброза сосудов) были последовательно отвергнуты. Случайной находкой при ангиографическом исследовании оказалось патологическое соустье между одной из ветвей верхней брыжеечной артерии и верхней брыжеечной веной, возникшее после резекции тонкой кишки и явившееся причиной портальной гипертензии, проявляющейся асцитом. Фистула была окклюзирована металлическими спиралями, после чего свободная жидкость перестала определяться, и больному были проведены запланированные сеансы ТАХЭ печени с эффектом.</p></abstract><trans-abstract xml:lang="en"><p>   A case of ascites developed in disseminated neuroendocrine small bowel tumor G1 (Ki-67 2 %) patient due to the unlikeliest of the possible reasons, i.e. iatrogenic mesenteric arterioportal fistula, is presented in the paper. The patient after palliative small bowel resection was preparing for the liver transarterial chemoembolization (TACE) when the fluid accumulation was revealed in the peritoneal cavity at ultrasound and MR imaging. The probable ascites etiologies (peritoneal carcinomatosis, carcinoid right heart failure, portal hypertension due to tumor compression or vascular elastic fibrosis) were consistently ruled out. The fistulation between the superior mesenteric arterial branch and the superior mesenteric vein developed shot after small bowel surgery and maintaining portal ascites was occasionally found at superior mesentericography. The ascites vanished after fistula occlusion with the metal coils, and the patient proceeded to the planned liver TACE therapies with good effect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нейроэндокринная опухоль</kwd><kwd>подвздошная кишка</kwd><kwd>метастазы в печени</kwd><kwd>трансартериальная химиоэмболизация</kwd><kwd>циторедукция</kwd><kwd>интервенционная радиология</kwd><kwd>мезентеральная артериопортальная фистула</kwd><kwd>асцит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ileum neuroendocrine tumor</kwd><kwd>liver metastases</kwd><kwd>transarterial chemoembolization</kwd><kwd>cytoreduction</kwd><kwd>interventional radiology</kwd><kwd>ascites</kwd><kwd>arterioportal fistula</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study had no sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ayantunde A., Parsons S.
