To lower blood pressure in select patients with very high (diastolic BP > 110) blood pressure and to preserve renal function (prevent kidney failure requiring dialysis) when the arteries to the kidneys are found to have narrowings.
First your doctor performs a complete history and physical exam. Then the initial study ordered may be a Renal artery duplex examination or a nuclear medicine scan. Ultimately, a renal artery arteriogram is required to further define the narrowings in the renal arteries.
Depending on the patient’s anatomy and overall health, several options may be considered. The narrowed renal arteries can be opened with a balloon procedure in carefully selected cases. In other patients a bypass is a more durable option. A bypass can be performed from a nearby artery to beyond the narrowed area of the renal artery.
