Chronic non cirrhotic extrahepatic portal vein obstruction (EHPVO) refers to the cavernomatous transformation of the portal vein (the so-called "portal cavernoma") which occurs following acute thrombosis of the portal vein in the absence of recanalization. In adults, EHPVO mainly occurs following thrombosis, while in children it may be related to congenital malformations and/or neonatal umbilical venous catheterization. However, 50% of the cases of EHPVO remain idiopathic [1]. Risk factors and associated diseases should be investigated (chapter 1). Indeed, the presence of a thrombophilic alteration, in particular myeloproliferative neoplasm impacts prognosis and determine a causal treatment.
