Pulmonary thromboembolism in β-thalassemia intermedia: Are we aware of this complication?

We describe a case of pulmonary thromboembolism in a 61-year-old woman with β-thalassemia intermedia and no other risk factors for thrombosis. Thromboembolism was documented by perfusion lung scan. We review the literature on this uncommon complication of thalassemia intermedia and discuss the pathogenesis and treatment options. A significant relationship between pulmonary thromboembolism and pulmonary hypertension in these patients was noted.
