DIALYSIS AV FISTULA REVASCULARIZATION
DIALYSIS AV FISTULA REVASCULARIZATION
What is dialysis fistuloplasty:
- It is a procedure that involves multiple techniques for removal of blockage in dialysis fistula.
Why it is necessary:
- According to KDOQI guidelines, fistula should be first priority for dialysis.
- After creation of fistula, it may not be work. So by this procedure, we can remove blockage and dialysis fistula may start working.
How it performed:
- In this procedure, depending upon the site of blockage different techniques like angioplasty, thrombus aspiration/thrombolysis or stenting are used.
- It involves small pinhole access within vessel and procedure performed under local anesthesia.
What are benefits:
- It is minimally invasive technique so no scar mark or stitches, minimum pain and done under local anesthesia.
- After procedure, dialysis fistula may be used for dialysis.
Precaution to be taken by patients:
Regular checkup for fistula,
- For any blockage or any damage to vessel wall.
- Monitoring of flow rate from fistula.
- For change in site of needle insertion.
Preparation for procedure:
- Few basic blood investigations like CBC, PT/INR, viral markers, serum electrolytes.
- Bring all the records including imaging record.
- Signing consent form.
What are risks:
- Very few and rare; hematoma, vessel wall damage, deep vein thrombosis (<1 case in 1000).
