Hemodynamic measurements included wedged hepatic vein (WHVP) and inferior vena cava (IVCP), and, in 12 patients, portal vein pressure (PVP). Hepatic vein pressure gradient (HVPG: WHVP\u2013IVCP) and portal vein pressure gradient (PVPG: PVP\u2013IVCP) were calculated.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> Nodular regenerative hyperplasia was associated in 24 patients with various diseases (oxaliplatin chemotherapy, treatment with purine antagonists, post liver transplantation, hematologic and rheumatologic conditions and HIV infection). Liver function parameters were either completely normal or slightly impaired. Patients were referred for gastroesophageal varices (<jats:italic>n<\/jats:italic>\u2003=\u200318), and\/or ascites (<jats:italic>n<\/jats:italic>\u2003=\u200311), and\/or splenomegaly (<jats:italic>n<\/jats:italic>\u2003=\u200320). In patients with varices or ascites, HVPG was lower than 10\u2003mmHg (a cut\u2010off point for the presence of varices and\/or ascites) in 15\/21, suggesting a pre\u2010sinusoidal component to their PHT confirmed by a PVP higher than 12\u2003mmHg in 12\/12 patients.<\/jats:p><jats:p>The mean difference between HVPG and PVPG was 8.7\u2003mmHg in these patients. Ten patients were treated by transjugular intrahepatic portosystemic shunt. None of them re\u2010bled, and one presented transient hepatic encephalopathy.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> Presinusoidal PHT associated with NRH is probably related to compression of portal venules by the regenerative nodules. In patients with HTP and a HVPG &lt;\u200310\u2003mmHg, the diagnosis of NRH must be suspected and PVP measured, which is important in the management of these patients.<\/jats:p>","DOI":"10.1111\/j.1440-1746.2012.07168.x","type":"journal-article","created":{"date-parts":[[2012,5,3]],"date-time":"2012-05-03T16:15:50Z","timestamp":1336061750000},"page":"1336-1340","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Hepatic hemodynamics in 24 patients with nodular regenerative hyperplasia and symptomatic portal hypertension"],"prefix":"10.1111","volume":"27","author":[{"given":"Julien","family":"Bissonnette","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre","family":"G\u00e9n\u00e9reux","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean","family":"C\u00f4t\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bich","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Perreault","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louis","family":"Bouchard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilles","family":"Pomier\u2010Layrargues","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,7,23]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/hep.1840110512"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.1996.d01-412.x"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/hep.21258"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/MEG.0b013e3283360021"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v17.i11.1400"},{"key":"e_1_2_5_7_2","first-page":"1012","article-title":"Hepatic hemodynamics in a patient with nodular regenerative hyperplasia","volume":"91","author":"Ueno S","year":"1996","journal-title":"Am.
