We aimed to present our long-term surveillance experience in patients with Budd-Chiari syndrome (BCS), and we retrospectively evaluated the natural history, results of thrombophilia studies, and the factors related to mortality.


Primary BCS is a rare form of vascular disease, secondary to underlying thrombophilia. Because of its rarity and heterogeneous nature, there is a scarcity of knowledge about the natural history of the disease.

Study and Results:

In 22 years, a total of 62 patients with primary BCS were followed in our tertiary hospital. We identified an acquired cause of BCS in 40 out of 62 patients (64.5%), whereas in 6 patients (9.7%), we found no identifiable cause. One or more thrombophilia causes were identified in 56 patients (90.3%). In 19 patients with myeloproliferative disease, 15 had Janus tyrosine kinase 2 mutation analysis and Janus tyrosine kinase 2 positivity was found in 10 patients. In regression analysis, portal vein thrombosis was found to be the only indicator of mortality, with an estimated instantaneous risk of 8.4.


In this study, we present one of the largest series of BCS in the English literature. We have shown that the multifactorial nature of underlying thrombophilia should be thoroughly investigated. In a patient with BCS, a clinician should be alert for the development or coexistence of portal vein thrombosis due to its deleterious effect on mortality.
