Study questions need for routine intervention in patients with renovascular disease
Date:10/13/2009

, Davis said. But the ability to detect the disease earlier does not mean that intervention should always be applied immediately upon detection, he added, because there is increasing evidence that not every case of renal artery stenosis will contribute to severe hypertension or poor kidney function.

"You can identify that the patient has stenosis, but not necessarily that it is causing, or is going to cause, a problem for that patient," Davis said. "The fact that you have stenosis doesn't necessarily mean you have to have something done about it."

In certain situations, management with medicine may be the most appropriate therapy, Davis said, adding that surgery or angioplasty with stenting could be considered when there is evidence that the condition is more serious, such as if blood pressure becomes increasingly difficult to manage with medication and/or if kidney function continues to decline.

The Centers for Medicare and Medicaid Services has not yet made any changes to the way it reimburses physicians and hospitals for treatment of renal artery stenosis. It is awaiting the results of several larger studies that are specifically designed to evaluate the usefulness of intervention for these patients.
