Thirteen participating sites-- including academic, community-based, inpatient and freestanding outpatient dialysis centers-- enrolled 190 patients (69 men, 121 women) with failing arteriovenous (AV) grafts in this study, said Haskal. Ninety-seven patients received stent grafts, with 93 undergoing balloon angioplasty (percutaneous transluminal angioplasty or PTA). There were no significant differences between graft and PTA groups with respect to demographics or relevant medical history. Nearly 51 percent of dialysis accesses treated with stent grafts remained open at six months, as compared to just 23 percent of those treated with balloon angioplasties. Treating physicians had a nearly 94 percent success rate at implanting the stent grafts. There were no differences in adverse events between the two approaches.
"Interventional radiologists work to keep access to the circulatory system open to ensure that patients with end-stage renal disease can continue to receive regular life-saving dialysis," noted Society of Interventional Radiology President Brian F. Stainken, M.D., FSIR, who represents the national organization of nearly 4,500 doctors, scientists and allied health professionals dedicated to improving health care through minimally invasive treatments. "This study is another example of the way in which interventional radiologists pioneer advances to improve health care for patients-- in this case, specifically for kidney failure patients," added Stainken, an interventional radiologist who is also president of the Imaging Network of Rhode Island and chair of the diagnostic imaging department at Roger Williams Medical Center in Providence, R.I.
When kidneys fail-- called chronic kidney or end-stage renal disease-- treatment in the form of regular dialysis (or hemodialysis) is needed to replace the kidney's job of ridding the body of toxic waste products to maintain fluid, electrolyte and acidbase balance. Before dialysis can beg
