Peculiar imaging findings were not pathognomonic for any of the known congenital and acquired portal vein anomalies: absence of a normal extrahepatic portal vein; splenic and mesenteric veins merging into a dilated left gastric vein; presence of an aberrant mesenteric venous collateral with a stenotic connection with the intrahepatic right portal branch; and absence of porto-systemic shunt. The case was successfully managed with percutaneous transhepatic portography and angioplasty.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Prompt non-invasive imaging characterization allowed to understand the singular vascular abnormality and mini-invasive interventional radiology management resolved portal hypertension and variceal bleeding.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s42155-021-00239-1","type":"journal-article","created":{"date-parts":[[2021,6,7]],"date-time":"2021-06-07T05:02:38Z","timestamp":1623042158000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Percutaneous transhepatic treatment of a unique portal vein malformation with portal hypertension in a pediatric patient"],"prefix":"10.1186","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4935-8110","authenticated-orcid":false,"given":"Paolo","family":"Marra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ludovico","family":"Dulcetta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia","family":"Pellegrinelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorenzo","family":"D\u2019Antiga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandro","family":"Sironi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,6,7]]},"reference":[{"issue":"3","key":"239_CR1","doi-asserted-by":"publisher","first-page":"842","DOI":"10.1148\/rg.2019180146","volume":"39","author":"BK Albers","year":"2019","unstructured":"Albers BK, Khanna G (2019) Vascular anomalies of the pediatric liver.
