Thrombophilia Profile in Budd-Chiari Syndrome and Splanchnic Vein Thrombosis: A Study from Western India.

AIM To estimate the prevalence of inherited prothrombotic risk factors in patients with splanchnic venous thrombosis (SVT) and Budd-Chiari syndrome (BCS) and to compare the risk factor profiles between these two groups. METHODS In this prospective study, patients with abdominal venous thrombosis were studied. The patients were divided into two groups on the basis of the veins involved; splanchnic venous thrombosis group [portal (PVT), splenic, superior mesenteric veins (SMV)] and Budd-Chiari group (hepatic vein, IVC thrombosis). Thrombophilia profile including protein C, protein S, antithrombin III, factor V Leiden mutation, activated protein C, factor VIII level, CD55, CD59, IgM cardiolipin, IgG cardiolipin, anti-β2 glycoprotein, JAK2 mutation, homocysteine levels, MTHFR and lupus anticoagulant was done in all patients. RESULTS Out of 30 patients, 23 patients had SVT, 7 had BCS, including 2 of the 23 patients with SVT had mixed venous thrombosis, PVT and SMV thrombosis. Risk factors were found in 21/30 (70%) patients [17/23 (73.9%) of PVT. 4/7 (57.1% of BCS] and multiple risk factors were overall present in 8/23(34.7%) patients of SVT. CONCLUSIONS Hereditary risk factors play an important role in the etiopathogenesis of abdominal venous thrombosis and hyperhomocysteinemia and protein S deficiency are the most common risk factors.
