Willcon, for me it all came about when the surgeon drew pretty diagrams on my chest and tummy, then sat me up, and all the diagrams on my tummy disappeared! He then suggested the presternal catheter, and I was so eager to do PD that I didn't give it a second thought. Sadly, many nephs don't mention PD because they have vested interests in hemo centers. It's all about the bucks for them.
