Reno-vascular disease in polycythaemia rubra vera.

Hypertension and polycythaemia rubra vera commonly occur in the same patient. This is regarded as coincidence and the hypertension does not respond to correction of polycythaemia. We report a case of renal artery stenosis occurring simultaneously with polycythaemia rubra vera and suggest that renovascular occlusive disease should be excluded in such patients with refractory hypertension.
