OVER the past two decades, Interventional Radiology has developed into an essential provider of percutaneous creation and management of access in hemodialysis patients. The role of interventional radiology in this patient population has developed into a broad range of procedures, including catheter placement and management, preoperative imaging for access, screening of and prophylactic intervention for failing hemodialysis conduits and fistulas, treatment of thrombosed conduits and fistulas, and salvage procedures designed to enhance the maturation of native fistulas. The development and proliferation of these interventions has been accomplished almost exclusively by interventional radiologists. These interventions are so integral to the care of the patient receiving hemodialysis treatment that they are strongly supported by the Dialysis Outcomes Quality Initiative (DOQI) Vascular Access Guidelines, published in 1997 (1) and updated in 2001 (2). Undoubtedly, the last thing interventional radiologists want to hear is the rumbling of another turf battle, but that is precisely what is happening in the area of hemodialysis access interventions. For many years, a very small group of nephrologists “borrowed” from our well-recognized name and began calling themselves “interventional nephrologists.” Until recently, the “interventional nephrology” movement was a small blip on the radar screen, but now, for a variety of reasons discussed herein, there is increased interest in this area from the nephrology community. Gradually, throughout the late 1990s, manuscripts published by “interventional nephrologists” became more frequent, billing for percutaneous procedures by the same specialists increased, and attention to this subject at nephrology meetings increased dramatically. In fact, there has been a hands-on course in “interventional nephrology” at the American Society of Nephrology meeting for the past three years. The year 2000 marked a turning point, and arguably the true onset of the “turf battle” over hemodialysis access interventions. In January of that year, the American Society of Nephrology and Renal Physicians Association published a document outlining training guidelines for nephrology fellowships, which include “interventional nephrology,” clearly defined and covering the entire spectrum of interventions currently performed by interventional radiologists in this patient population (3). Later in the year, the formation of the American Society of Interventional Nephrology was announced. Also during 2000, a proliferation of freestanding “interventional nephrology” centers, largely Baxter’s RMS Lifelines, allowed nephrologists to bypass hospital credentials committees by performing interventions outside of the hospital setting. Until this point, nephrologists had largely been unable to receive credentials for percutaneous interventions precisely because of their lack of training, which was obvious to even the most liberal credentials committee. “Training centers” are now available to nephrologists in several places throughout the country (4,5) where a 2-week course is considered “acceptable training” to allow performance of these procedures. The quote at the beginning of this Commentary reflects this sentiment. To make matters worse, medical device manufacturers are promoting the concept, offering 1and 2-day “training courses” to nephrologists, cardiologists, and surgeons; one of the authors of this article has been approached repeatedly to provide such “training.” If this sounds far-fetched, or if the reader is thinking, “this won’t happen here,” consider the following: Late this year, the Society of Cardiovascular & Interventional Radiology (SCVIR) From the Department of Radiology (S.O.T.), University of Pennsylvania Medical Center, Philadelphia, Pennsylvania; Department of Radiology (R.D.G.), Washington Hospital Center, Washington, DC; Department of Radiology (M.B.), Swedish Covenant Hospital, Chicago, Illinois, and Department of Radiology (S.A.), Open Access Vascular Access Center, Miami, Florida.
