Flipside of the dialysis argument

Although I don’t have the expertise to take a position in the debate about chronic cerebrospinal venous insufficiency, Stanbrook and Hébert’s aside about the common finding of venous stenosis in patients receiving dialysis 1 lends itself to a corollary. Since venous angioplasty of stenosed dialysis access veins is a common procedure with a low rate of complication, it is somewhat disingenuous for those railing against Zamboni’s treatment 2 to claim that it is new, unproven or potentially dangerous.
