Glanzmann thrombasthenia complicated by frequent myeloproliferative neoplasm-related thromboembolism: thrombosis occurring regardless of αIIbβIII integrin deficiency.

A patient with Glanzmann Thrombasthenia developed recurrent venous thrombosis with a positive myeloproliferative neoplasm. This indicates that the platelet aIIbβIII integrin has no role in venous thrombosis. We discuss the other potential mechanisms that are involved. In addition, we describe the successful use of dabigatran in this patient.
