Vascular Access for Dialysis Procedures

AV Fistula Revision

This refers to the surgical or endovascular procedures performed to correct problems such as stenosis, occlusion, flow dysfunction, or loss of function that develop in an existing arteriovenous fistula (AV fistula) used for hemodialysis.

Procedure Duration :

30 - 90 min

What Is AV Fistula Revision?

AV fistula revision is the repair of fistulas that do not function properly, fail to provide adequate blood flow during dialysis, or develop complications. These procedures aim to preserve the existing fistula and reduce the need to create a new vascular access.

How Is AV Fistula Revision Performed?

The revision method is determined according to the specific problem identified in the fistula.

Surgical Revision

  • Correction of the stenotic segment
  • Creation of a new anastomosis
  • Repair of the aneurysm

Endovascular Revision

  • Balloon angioplasty
  • Stent placement (in selected cases)
  • Thrombectomy (if a clot is present)

Before the procedure, the fistula is evaluated in detail with Doppler ultrasonography. The procedures are usually performed under local anesthesia.

  • Development of stenosis in the fistula
  • Fistula occlusion (thrombosis)
  • Insufficient blood flow during dialysis
  • Difficulty with needle insertion
  • Inadequate maturation of the fistula
  • Swelling, pain, or bleeding
  • Development of an aneurysm
  • Preservation of the existing fistula
  • Improved dialysis efficiency
  • Reduced need for creating a new vascular access
  • Prevention of interruptions in the dialysis process

After the revision, the function of the fistula is closely monitored. If necessary, dialysis can be resumed in a short time. The fistula function is followed with regular check-ups.

AV fistula revision should be considered for all patients in whom dysfunction of the hemodialysis fistula is detected. Early intervention is critical in preventing fistula loss.
