The pulmonary hypertension developed without a surgical portal-systemic shunt, and at autopsy there was no evidence of a large spontaneous shunt. This association of pulmonary arterial hypertension and portal venous hypertension without either intrinsic liver disease or a large portal-systemic anastomosis has not been reported previously. Our case supports the concept that portal hypertension with its attendant portal-systemic collateral circulation may be the major predisposing cause of pulmonary hypertension both in intrinsic liver disease and extrahepatic portal vein obstruction.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1002\/hep.1840030419","type":"journal-article","created":{"date-parts":[[2010,7,5]],"date-time":"2010-07-05T12:08:19Z","timestamp":1278331699000},"page":"588-592","update-policy":"http:\/\/dx.doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":42,"title":["Primary Pulmonary Hypertension: An Unusual Case Associated with Extrahepatic Portal Hypertension"],"prefix":"10.1097","volume":"3","author":[{"given":"Mark D.","family":"Cohen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lewis J.","family":"Rubin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wayne E.","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer A.","family":"Cuthbert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"10.1002\/hep.1840030419-BIB1|cit1","doi-asserted-by":"crossref","first-page":"376","DOI":"10.1161\/01.CIR.22.3.376","article-title":"\u201cPrimary\u201c pulmonary hypertension with coexisting portal hypertension.
