Pathology of Noncirrhotic Portal Hypertension

  • I. R. Wanless


Portal hypertension is the result of obstruction to the hepatic vasculature. The hepatic lesion most commonly associated with portal hypertension is cirrhosis. The principal feature which defines cirrhosis is the presence of fibrous septa which subdivide the surviving parenchyma into nodules. Septa arise after hepatocellular necrosis. Noncirrhotic portal hypertension (NCPH) develops after an injury that is more specifically directed to vessels or adjacent portal structures, so that septa are absent or minimal.
