Management and conduct of vascular diseases of the portal system

Aneurysms and thromboses of the portal vein are rare pathologies of the portal system that commonly follow an asymptomatic course. The vast majority of cases are diagnosed as incidental findings during imaging studies. Symptoms of aneurysms are the result of mass effects, while thrombosis symptoms are a function of the liver's ability to form a collateral circulation network in the thrombosis. The scant experience with such cases poses a dilemma for patient management and so the vast majority of authors choose an expectant approach with rigorous patient surveillance and only intervene in symptomatic patients. We report one case of an aneurysm of the portal vein and one case of portal vein thrombosis and discuss management and observation of these patients.
