We expect to learn a great deal about how best to treat the millions of Americans with hypertension and atherosclerosis of the kidney arteries,, says co-principal investigator Timothy Murphy, MD, an interventional radiologist at Rhode Island Hospital and associate professor of diagnostic imaging at Brown Medical School.
The study is led by the following institutions: Medical College of Ohio, Rhode Island Hospital/Brown Medical School, University of Maryland, University of Virginia School of Medicine, University of Minnesota, Beth Israel Deaconess Medical Center, Harvard Clinical Research Institute, and Brigham and Women,s Hospital.
Explosive growth in renal artery interventional procedures; More cardiologists performing procedures, 1 Sept 2004 [cached]
In 1996 radiologists performed 4,700 renal artery interventional procedures (balloon angioplasty, stent or both), while cardiologists performed 2,380, said Timothy Murphy, MD, associate professor of radiology, Brown University Medical School, and lead author of the study.By 2000, cardiologists did 9,220 of these procedures (a 3.9-fold increase in annual volume) while radiologists increased the performance of this service to 7,660 (a 1.6-fold increase in annual volume)."It is important to note that cardiologists self-refer, and that could be one of the reasons why there is such a large increase in the number of procedures they are doing," Dr. Murphy said.
The greatest increase in the use of renal artery interventions occurred in the southeast (Alabama, Kentucky, Mississippi, North Carolina, South Carolina and Tennessee) with an increase from 22 per 100,000 Medicare beneficiaries in 1996 to 86 per 100,000 beneficiaries in 2000.The annual volume of renal artery interventions by cardiologists increased more than 15-fold in this region, Dr. Murphy said."If this growth rate by cardiologists in the southeast region continues, at the end of 10 years, every man, woman and child in these states will have had a renal artery stent," he said.
The lowest rate of increase was in the northeast (Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, Vermont): 18 per 100,000 beneficiaries in 1996 to 26 per 100,000 beneficiaries in 2000.The regional differences "prove there is no consensus on how these patients should be treated.Somebody is wrong.Patients are either being over or under treated," Dr. Murphy said.
"Blockages in the renal arteries is common, seen in 6-18% of patients undergoing coronary arteriography and in 16-40% of those patients undergoing aortography for aneurysms or peripheral vascular disease," Dr. Murphy said.The average hospital cost for a renal artery stent is about $10,000, Dr. Murphy said."If you look at these numbers, and you look at the mind-boggling growth in renal artery interventional procedures, you could be talking about several hundred million dollars, even up to more than a billion dollars annually to treat these patients," he said.
A multi-center clinical trial is scheduled to begin the end of this year to determine the best role for renal artery angioplasty.In the past, clinical trials have looked at its effect on hypertension, and have found little benefit, Dr. Murphy said.This trial will examine its affect on stroke, heart attack, heart failure and worsening renal function, he said.This study should help resolve the confusion regarding the need for renal artery stenting, he added.

Society of Interventional Radiology Names Timothy P. Murphy, M.D., FSIR, as 2011-12 President
CHICAGO, March 30, 2011 /PRNewswire-USNewswire/ -- Timothy P. Murphy, M.D., FSIR, an interventional radiologist and director of the Vascular Disease Research Center at Rhode Island Hospital in Providence, assumed office as the 2011-12 president of the Society of Interventional Radiology during its 36th Annual Scientific Meeting in Chicago, Ill. SIR is a national organization of nearly 4,700 doctors, scientists and allied health professionals dedicated to improving health care through minimally invasive treatments.
"The need is great to educate the public and hospital administrators on the safety and cost-effectiveness of interventional radiology treatments," said Murphy. "Strong interventional radiology programs are in the best interests of institutions, physicians and--above all--patients. Interventional radiology therapies are effective and a relatively low-cost option for surgical issues and complement the needs of accountable care organizations, or ACOs, very nicely," he added.
When asked about strategic goals, Murphy explained, "I see the strategic objectives of the Society of Interventional Radiology as having the ability to develop or adapt new procedures so that we can better serve patients; to validate those procedures so that we can show their value; to ensure reimbursement for the procedures; and to make certain that interventional radiologists are well-placed to provide those services indefinitely into the future."
"Interventional radiologists are caring professionals who play pivotal roles in patient care for many disease conditions. The diverse collection of critical services provided in a timely manner with a high degree of expertise by on-site interventional radiologists delivers tremendous value to a hospital," said Murphy. "Whether in a traditional hospital-based practice or subspecialty office-based environment, interventional radiologists are uniquely qualified to deliver the gamut of interventional medicine in a manner no other specialty can duplicate," he noted.
Murphy explained what he thinks are the most interesting developments in interventional radiology at this moment: the expanding role for interventional radiologists in acute stroke care, the opportunities afforded by miniaturized endovascular aneurysm repair, or EVAR, devices, and potential services that can be offered for chronic cerebrospinal venous insufficiency or CCSVI (where there is a blockage in the veins that drain blood from the brain and spinal cord and return it to the heart), and the interventional treatment of venous diseases like varicose veins and deep vein thrombosis.
Murphy holds a patent for a stent graft system and is widely published. He has authored and co-authored numerous scientific articles that have appeared in numerous medical journals including SIR's flagship publication, the Journal of Vascular and Interventional Radiology, and the Journal of the American Medical Association. He has contributed to pieces on angiography, cardiovascular care, stenting and deep vein thrombosis, among many others. Murphy has been active within SIR on numerous committees and has written many times for SIR on the logistics of clinical practice. He has served as a distinguished reviewer and associate editor for JVIR.
"Interventional radiologists will continue to offer patients and the health care system what no other specialty can: the most in-depth knowledge of the least invasive treatments available using imaging guidance--treatments that offer less risk, less pain and less recovery time compared to open surgery--coupled with diagnostic and clinical experience across diseases and organ systems," said Murphy.
Murphy received his bachelor and medical degrees from Boston University. He completed an internship at Cambridge Hospital in Cambridge, Mass., and served his residency and chief residency at Rhode Island Hospital and the Alpert School of Medicine at Brown University.
The 2011-12 SIR president has held several academic positions at Brown University School of Medicine. He is a fellow of SIR, the American College of Radiology, the American Heart Association and the Society of Vascular Medicine. He is a member of the American Medical Association, the Massachusetts Medical Society, the Rhode Island Radiological Society; Murphy is also an American Heart Association Premium Professional Silver Heart member (in recognition for continued service).
