Forum Name: Dialysis

Question: Shunt in arm

 Cantante - Fri Jun 15, 2007 1:29 pm

My mother (62)has Wegener's and went into kidney failure and was on dialysis for 6 months before kidneys came back. Ironically, her kidneys came back a week after shunt was placed in her arm. Even though she is not on dialysis anymore, she still has the shunt in her arm and has recently noticed 2 knots along the scar of the shunt. Is this normal?

She is currently on Cytoxan, prednisone, renavite, and lasik pill.

User avatar Dear Cantante,
Without visually inspecting the arm, I can say that yes, frequently "knots" can be noted along the placement of the scar. An AV fistula (arteriovenous fistula) or shunt, is a surgically created shortcut or bypass from an artery to a vein for the purpose of dialysis. The anastamosis (joining) of the two vessels can be felt as scar tissue. The important thing is that there is a strong bruit or "thrill" felt along the scar line which indicated that the fistula is working. I am delighted on your mom's behalf that she has had renal recovery and the only caution I will remind you is that she should never have blood pressures or lab work done on that arm from here forward. The next time she has followup for the surgery, ask the surgeon about the "knots".
