Review article: the modern management of portal vein thrombosis Chawla Y; Duseja A; Dhiman RKAliment Pharmacol Ther 2009[Nov]; 30 (9): 881-94BACKGROUND: Portal vein thrombosis (PVT) is an important cause of portal hypertension. It may occur as such with or without associated cirrhosis and hepatocellular carcinoma. Information on its management is scanty. AIM: To provide an update on the modern management of portal vein thrombosis. Information on portal vein thrombosis in patients with and without cirrhosis and hepatocellular carcinoma is also updated. METHODS: A pubmed search was performed to identify the literature using search items portal vein thrombosis-aetiology and treatment and portal vein thrombosis in cirrhosis and hepatocellular carcinoma. RESULTS: Portal vein thrombosis occurs because of local inflammatory conditions in the abdomen and prothrombotic factors. Acute portal vein thrombosis is usually symptomatic when associated with cirrhosis and/or superior mesenteric vein thrombosis. Anticoagulation should be given for 3-6 months if detected early. If prothrombotic factors are identified, anticoagulation should be given lifelong. Chronic portal vein thrombosis usually presents with well tolerated upper gastrointestinal bleed. It is diagnosed by imaging, which demonstrates a portal cavernoma in place of a portal vein. Anticoagulation does not have a definite role, but bleeds can be treated with endotherapy or shunt surgery. Rarely liver transplantation may be considered. CONCLUSION: Role of anticoagulation in chronic portal vein thrombosis needs to be further studied.|Adult[MESH]|Anticoagulants/therapeutic use[MESH]|Carcinoma, Hepatocellular/complications[MESH]|Child[MESH]|Humans[MESH]|Hypertension, Portal/etiology[MESH]|Liver Cirrhosis/complications[MESH]|Liver Neoplasms/complications[MESH]|Portal Vein/*surgery[MESH]|Thrombectomy[MESH]|Thrombolytic Therapy[MESH]|Venous Thrombosis/diagnosis/*therapy[MESH] |
