Portal vein thrombosis (PVT) is an uncommon cause of presinusoidal portal hypertension. Among various hepatoportal disorders, noncirrhotic portal hypertension conditions such as idiopathic portal hypertension (IPH) are considered to have a close relation with PVT. PVT is known to have several predisposing conditions, including infection, malignancies, and coagulation disorders. There is growing interest and recognition that deficiencies in proteins C and S are associated with a hypercoagulable state. These deficiencies are regarded as key factors of systemic hypercoagulability and recurrent venous thromboembolism. We report the case of a 19-year-old male diagnosed as IPH with PVT and combined deficiencies in proteins C and S.
