Portosystemic shunts are common findings in patients with cirrhosis, causing gastroesophageal varices, hepatic encephalopathy, and others. However, there is no consensus or literature describing how to manage asymptomatic patients with portosystemic shunts and normal liver.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>The patient was a 39-year-old female who underwent donor right hepatectomy for living donor liver transplantation. The patient was healthy by nature, however, developed hepatic encephalopathy after the surgery due to a development of portosystemic shunt. Portosystemic shunt stole portal blood flow, and imaging modalities revealed narrowing of the portal trunk, representing prolonged depletion of portal blood flow. Balloon-occluded retrograde transvenous obliteration (B-RTO) was performed for occlusion of the portosystemic shunt. B-RTO increased portal blood flow, and hepatic encephalopathy with hyperammonemia was successfully resolved without the outbreak of any other symptom of portal hypertension.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>A congenital portosystemic shunt itself is not a contraindication for donor hepatectomy, but perioperative endovascular shunts occlusion or intraoperative ligature of these shunts should be considered.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40792-022-01533-3","type":"journal-article","created":{"date-parts":[[2022,10,6]],"date-time":"2022-10-06T11:03:04Z","timestamp":1665054184000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Caution for living donor liver transplantation with congenital portosystemic shunt: a case report"],"prefix":"10.1186","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4070-7329","authenticated-orcid":false,"given":"Yoshihiro","family":"Nagao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsuya","family":"Toshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akinari","family":"Morinaga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Tomiyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukiko","family":"Kosai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomonari","family":"Shimagaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Tomino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huanlin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Kurihara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeo","family":"Toshima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazutoyo","family":"Morita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinji","family":"Itoh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noboru","family":"Harada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoharu","family":"Yoshizumi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,10,6]]},"reference":[{"issue":"34","key":"1533_CR1","first-page":"1113","volume":"47","author":"T Akahoshi","year":"2000","unstructured":"Akahoshi T, Nishizaki T, Wakasugi K, Mastuzaka T, Kume K, Yamamoto I, et al.
