Answer

For most patients with RVHT, with the exception of persons with fibromuscular dysplasia, it is unclear whether revascularization will be beneficial. Fibromuscular dysplasia responds well to angioplasty. The causes of renovascular hypertension include atherosclerosis, fibromuscular dysplasia, coarctation of the aorta, embolic renal artery occlusion, aneurysm of the renal artery, and diffuse arteritis. Additionally, causes of diffuse bilateral renal ischemia (eg, accelerated hypertension, vasculitis, hepatitis B, and IV drug abuse) may also lead to hypertension.
