Renal Artery

Abstract

Renovascular disease encompasses a wide range of etiologies and is recognized with increasing frequency given less invasive and widespread diagnostic imaging studies. Renovascular hypertension secondary to renal artery occlusive disease is the most common form of surgically correctable hypertension. Atherosclerotic renal artery disease accounts for approximately 95% of renovascular hypertension. Fibromuscular dysplasia is the most common nonatherosclerotic renal artery disease. Renal artery aneurysms are rare, however, can be life-threatening and should be repaired, particularly in women of childbearing age and those with associated hypertension. Surgical treatment continues to evolve and includes both endovascular and open techniques. Open techniques are generally reserved for unstable patients or endovascular failure.
