Renovascular hypertension

Renovascular hypertension can be caused by renal artery stenosis (atheroscl erosis or fibromuscular dysplasia), arteriitis, embolism, aneurysm, tumors, cysts, neurofibromatosis and artery stenosis after renal transplantation. This type of hypertension is probably based on renal hypoperfusion followed by stimulation of the renin-angiotensin-aldosterone system. The choice of diagnostic procedures includes Color duplex. ultrasonography and captoptil scintigraphy as screening methods. Arterial digital subtraction angiography is the golden standard for evaluation of renal artery stenosis, spiral-CT angiography and MRI angiography are also suitable for diagnosis of renal ar tery stenosis. Angioplasty is the treatment of choice in hemodynamic-releva nt artery stenosis. Surgical treatment is indicated in special cases. In or der to avoid possible complications of invasive diagnostic procedures inter ventional treatment management of renovascular hypertension should be perfo rmed in clinical centers for renal diseases and hypertension.
