AV Fistula - How It Benefits You?

AV Fistula - How It Benefits You?

The human circulatory system is a highly complex and well-orchestrated system designed with two sets of channels. The arteries are a chain of vessels which carry oxygenated blood to all parts of the body from the heart. The venous system, on the other hand, carries impure or deoxygenated blood from each of the end organs to the heart. These start from minute branches in the distant parts of the body and gradually grow in size until they reach the heart.

These two channels do not interact unless either created artificially or in disease conditions. Naturally, these could be due to developmental anomalies or as a result of an aneurysm and would require a surgical correction. The AV fistula is, however, commonly created naturally in people who have to undergo hemodialysis.

Why an AV fistula: Generally, an artery in the forearm is sewn into a vein in the forearm. This AV fistula may take about 4 months to heal or mature, and a needle is then inserted into the vein during dialysis. When an AV fistula is created, there is a decrease in the peripheral resistance as the blood does not have to exert as much pressure as before, and there is an easy movement of blood into the veins.

How to care for it:

  1. There could be initial limitations on the amount of weight that can be lifted
  2. Keep the dressing in place for 1 to 2 days
  3. Do not sleep on the fistula arm
  4. Do not wear jewellery on the arm
  5. Always wash hands before touching the access
  6. Avoid lifting heavy objects using the hand
  7. Avoiding damage to the arm like cuts or bruises
  8. Regular checking for the pulse or thrill in the arm
  9. Monitoring for signs of infection (redness, blood clots, swelling, pus formation, etc.)


  1. Uses the body’s own blood vessels, no artificial material (as in catheter for instance)
  2. Reduced chances of clotting
  3. It provides good blood flow for dialysis
  4. Is more effective than other types of access (graft or catheter)
  5. Lesser complications compared to other access types
  6. Is done on an outpatient basis and are less expensive
  7. Usually last longer than other access methods


  1. Longer maturity time (sometimes up to 4 months), so are not available for ready use
  2. Stenosis or narrowing of the vessels is common, sometimes leading to blood clots.
  3. If they fail to mature, a fresh fistula may need to be created
  4. Usually created on the forearm, so are quite visible

Please get for a routine medical check up as a preventive measure. The swelling can happen due to various reasons like injury, sitting or standing for long hours, any internal problem which needs to be probed by a doctor. Please revert after the visit to the doctor (do some routine tests like CBC, ESR, blood sugar, urine routine etc ).

Lybrate-user ji, Thanks for the query. The signs mentioned by you like foot being felt cold to touch, and change in colour do point to some vascular issue. So please contact a surgeon and if possible get a colour Doppler test done to see if there is any affection to the blood vessels. Thanks.

It could most likely be due to the pollution which could cause allergy or allergy to certain items you use or it can be due to the work place or house enveroinment, you can take citrizine 10 mg 1 tab at night for 3 days and you can also you calamine lotion twice daily and see if there is any improvement, also try to modify your food habits to see if you have any allergies to any food items or household substaces and personal belonging such as soap, clothes ect. If you are not well after few days, then it is better to consult a dermatologist.
