The cost of a dialysis fistula is about$2000-3000. Dialysis fistulas are mainly for patients with uremia, who need hemodialysis for long-term survival, but if there is a risk of infection from long-term placement of a tube in the femoral or internal jugular vein, then an endovenous fistuloplasty in the forearm or lower extremity is required to reduce the risk of infection. The cost of endovenous fistuloplasty is about$2,000 to$3,000, and the procedure is covered by health insurance, so the cost is very limited. After endovenous fistuloplasty, it is important to avoid pressure on the fistula, to avoid taking blood pressure on this side, and to avoid weight-bearing on this side when lifting things. It is important to keep the area clean after the puncture to avoid infection. When the patient has diarrhea or is severely dehydrated due to heavy sweating, it is important to monitor the patency of the fistula to avoid blockage. It can be said that the arteriovenous fistula is the lifeline of the uremic patient and must be protected.
