RESUMO
Protein C deficiency is a well recognized risk factor for development of venous thromboembolism but has never been reported to be associated with development of liver cirrhosis .We report a case of a 26 years old female who presented with multiple thrombosis involving superior mesenteric vein ,main portal vein and multiple cerebral veins. Liver biopsy done was reported as cirrhosis possibly due to Wilson’s disease. However no improvement was seen with D penicillamine and patient’s condition detiorated. Further, work up of patient revealed absence of Protein C levels in the plasma. So finally the case was diagnosed as Cirrhosis liver with Protein C deficiency as the likely etiology. We conclude that Protein C deficiency should be investigated in patients with cirrhosis with thrombotic lesions of unknown etiology.
