Thrombocythemia and thrombosis of the adrenal vessels

The authors describe a case of primary thrombocythemia and thrombosis of the adrenal vessels which they were able to examine by arteriography of the renal and adrenal arteries, by adrenal CT and at autopsy following the patient’s death. The available research data and hypotheses concerning the pathogenesis of thrombosis and hemorrhage in thrombocythemia are reviewed, but the relationship between platelet number and function and the incidence of thrombotic and hemorrhagic complications has not yet been clearly established. Pathogenesis of thrombosis and hemorrhage in suprarenal vessels is not clear and the majority of authors postulate early venous damage.
