Cardiac (congestive) hepatopathy, wherein outflow obstruction occurs secondary to backflow from a failing heart, and Budd Chiari syndrome, wherein obstruction of outflow occurs secondary to obstruction, usually thrombotic, have overlapping features, including sinusoidal dilation with emphasis upon the central vein, space of Disse erythrocytes, centrilobular inflammation, hemorrhage, bile ductules, and hemosiderin, and portal inflammation, fibrosis and bile ductular reaction. Centrilobular dropout/necrosis is more common in Budd Chiari syndrome, while peri-central venous and sinusoidal fibrosis are more common in cardiac hepatopathy. In end stage liver, fibrosis for cardiac hepatopathy comprises stellate centrizonal fibrous with haphazard spread, as opposed to the more frequent nodular cirrhosis in Budd-Chiari. Clinical findings are important to take into account, as cardiac failure is usually well known at the time of diagnosis as are the clinical predictors of Budd Chiari syndrome, prothrombotic states, myeloproliferative diseases, and oral contraceptive use. <ref name=pmid27681331 >{{cite journal |author=Gonzalez RS, Gilger MA, Huh WJ, Washington MK |title=The spectrum of histologic findings in hepatic outflow obstruction |journal= Arch Pathol Lab Med |volume=141 |issue= |pages=98 |year=2017 |pmid= 27681331 ||doi= 10.5858/arpa.2015-0388-OA |url=http http://www.archivesofpathology.org/doi/10.5858/arpa.2015-0388-OA?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%3dpubmed&code=coap-site }}</ref> | |||

Patient with congestive heart failure and stage I fibrosis. A. Dilated and undilated sinusoidal regions. B. Thrombi in sinusoids; glycogenated nuclei likely reflect patient’s diabetes mellitus. C. Dilated portal vein. D. Reticulin shows black lines of bridging, too thick for collapse. E. Trichrome shows space of Disse collagenization (pericellular fibrosis). F. Trichrome shows bridge beginning off to right; when it is more than a mere spike, it is a bridge. | |||
