Can it get any better?

So with all the exciting preparations going on for Gma great adventure this Friday....she came home early from dialysis today.
Her access is clotted again!!! Her last clot was Sept. 13th. This is her first clot since getting the new graft! After she got home today I was reading up on the problem via the internet and found out that her new AVF has greater chances of clotting than her old one. It seems that human blood vessels produce something to help keep you from clotting. The stuff they did the new one out of is the same stuff they make teflon coating out of and because it is "teflon" it does not produce....anything! So, here I thought we'd have weeks, months, years of no problems...and yee haw....she clots! I'm trying to find out if there is something we should be doing to keep it from clotting.....haven't found anything out yet! One of her transporters says we might be leaving the bandage on to long after dialysis. Sounds to simple. Who knows!
Stay tuned....tomorrow I'll tell you how it all went!!!
