Abstract：
Porto-sinusoidal vascular disease (PSVD) is the medical diagnosis for a patient who has portal hypertension in the absence of cirrhosis on liver biopsy. There are several specific histologic findings for PSVD, including obliterative portal venopathy, nodular regenerative hyperplasia, and incomplete septal fibrosis. Epidemiologic reports vary widely among regions; PSVD comprises less than 10% of causes of portal hypertension in Western countries but incidence has been found to be as high as 48% in India. There is an expansive list of etiologies that have been reported to cause PSVD.
