The current status of surgical therapy for renal artery disease.
The first reports of surgically curable hypertension in the late 1930s led to enthusiasm among clinicians for removing kidneys with arterial stenosis in hypertensive patients. The development of vascular surgical techniques in the 1950s made it possible to achieve successful renal revascularization in many of these cases. However, the cause and effect relationship between a stenotic renal artery lesion and hypertension was poorly understood and many patients treated surgically had no improvement of blood pressure postoperatively. Continued experience in this field during the past two decades has significantly improved our understanding of the natural history and functional significance of renovascular disorders. Patients with renovascular hypertension can now be identified with a high degree of accuracy and successful renal revascularization is possible in most cases. Nevertheless, multiple factors must be weighed in determining whether medical or surgical therapy is more appropriate for a given patient. These include the causal relationship of renovascular disease to hypertension, the adequacy of blood pressure control with medical therapy, the natural history of untreated renovascular disease with particular regard for the risk of sustaining impaired renal function, the medical condition of the patient, the morbidity and results of surgical therapy, and the availability of other therapeutic options such as percutaneous transluminal dilatation.
