Abstract
A 36-year-old male was evalued for treatment-resistant hypertension. A high platelet count 828. 109 l1, led to the diagnosis of essential thrombocythemia (ET). Aorto-renal angiography revealed critical bilateral renal artery stenosis and coronary angiography showed three-vessel disease. Percutaneous transluminal renal angioplasty was only partially successful. The patient received a 12-week course of busulphan and subsequently the thrombocyte count decreased to 200. 109 l1 Renal angiography 12 months later showed bilateral regression of the renal artery stenosis with lowering of the blood pressure to normal levels.
Key Words: Essential thrombocythemia hypertension regression of stenosis renal artery stenosis
