Non-cirrhotic portal hypertension (NCPH) is mainly related to vascular disorders in the portal system, granuloma formation with periportal fibrosis or genetic alterations affecting the hepatobiliary system. For the diagnosis of the so-called idiopathic NCPH, it is essential to rule out chronic liver diseases associated with progression to cirrhosis as viral hepatitis B and C, alcoholic and non-alcoholic fatty liver, autoimmune disease, hereditary hemochromatosis, Wilson's disease as well as primary biliary cirrhosis and primary sclerosing cholagitis. This mini review will focus on the most common types of NCPH, excluding the idiopathic NCPH. Primary Budd-Chiari syndrome, characterized by obstruction of hepatic venous outflow, must be distinguished from sinusoidal obstruction syndrome, a cause of portal hypertension associated with exposure to toxic plants or therapeutic agents. Noninvasive imaging methods usually help the diagnosis of both Budd-Chiari syndrome and portal thrombosis, the later a relatively frequent cause NCPH. Clinical presentation and management of these vascular disorders are evaluated. Schistosomiasis, a worldwide spread endemic parasitic disease, may evolve to severe forms of the disease with huge spleen and gastroesophageal varices due to presinusoidal portal hypertension. Although management of acute upper gastrointestinal bleeding is similar to that of cirrhosis, prevention of rebleeding differs. Instead of portosystemic shunt procedures, the esophagogastric devascularization with splenectomy is the accepted surgical alternative. Its association with endoscopic therapy is suggested to be the best option for PH due to schistosomiasis. In conclusion, the prompt diagnosis of the disorder leading to non-cirrhotic portal hypertension is essential for its correct management.
