|---|
Pulmonary hypertension is a common and debilitating condition which is increasingly being recognized in haematological patients. This is particularly so in haemolytic diseases like thalassaemia and myeloproliferative conditions like idiopathic myelofibrosis. Recently, splenectomy, which may be required for some of these conditions, have been linked to this complication although the exact pathophysiology is still not established. The manuscript explains the role of the less recognized lung megakaryocytes in the development of this complication.
