AV Fistula Blockage Management

An AV fistula is a surgical connection between an artery and a vein, commonly created for hemodialysis. Over time, it can become blocked due to clotting, narrowing, or improper blood flow, which may affect dialysis efficiency. AV Fistula Blockage Management helps restore proper circulation and maintain fistula function.

Treatments

  • Endovascular procedures: Angioplasty or stent placement to open narrowed veins.
  • Thrombectomy: Removal of clots to restore blood flow.
  • Surgical revision: Repair or creation of a new fistula if damage is severe.
  • Medications: Blood thinners in select cases.

Symptoms and Causes

  • Symptoms: Reduced thrill or pulse at fistula site, swelling, pain, prolonged bleeding after dialysis, or difficulty with dialysis sessions.
  • Causes: Blood clots, vein narrowing (stenosis), repeated needle punctures, infection, or poor fistula care.

Prevention

  • Regularly check fistula for thrill/pulse.
  • Maintain good hygiene at access site.
  • Avoid pressure, tight clothing, or sleeping on fistula arm.
  • Control risk factors like diabetes, high BP, and cholesterol.
  • Routine follow-up with a vascular specialist.
