Multiple venous thromboses and membranous obstruction of inferior vena cava in association with hereditary protein C deficiency: a case report.

A forty year old male presented with multiple dilated venous channels over the whole body involving both inferior and superior vena caval territories, along with features of chronic liver disease and portal hypertension. On investigation, he was found to have membranous obstruction of the inferior vena cava (MOIVC) as well as obstruction of both brachiocephalic and right subclavian veins and 'hereditary protein C deficiency'. He was managed successfully by percutaneous transluminal balloon angioplasty for the inferior vena cava (IVC) obstruction and was doing well on follow-up.
