Portal Vein Thrombosis and Budd-Chairi Syndrome Due to In-apparent Polycythaemia Vera

Portal vein thrombosis (PVT) is an uncommon finding in patients without cirrhosis. Budd-Chiari syndrome is caused by occlusion of the hepatic veins that drain the liver, and the underlying aetiology is difficult to determine.It is characterised by the classic triad of abdominal pain, ascites, and liver enlargement. Myeloproliferative diseases, particularly polycythemia vera, are the primary cause of this syndrome. The latter may result in multiple splanchnic thrombosis, including portal vein thrombosis, which is particularly significant for its clinical outcomes of ascites, esophageal varices, collateral vessel genesis, and so on. We present a case of a 37-year-old man who presented with severe abdominal pain, abdominal distension, and budd chairi syndrome caused by polycythemia Vera.
