Renal Artery (Kidney) Revascularization
Indication: 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.
Preoperative Evaluation: 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.
Procedure: 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.
Length of Stay: One to three day stay in the intensive care unit (ICU) followed by four to six days in a regular room.
Recovery: Four to six weeks with no driving for 10-14 days and no heavy lifting (over 15 lbs.) for six weeks.
