WHAT IS AV FISTULA AND HOW SUCCESSFUL IS IT?

An AV fistula is an artificial surgical connection between an artery and a vein. It makes a vein fat, thick and strong to sustain dialysis needle.


Worldwide success rate (that is a fistula through which uneventful dialysis is initiated) is 60-70%, but with ultrasound screening we can get better results.


WHAT PRECAUTIONS ARE TO BE TAKEN IN A FISTULA LIMB?

No prick, blood sampling, blodd pressure recording is to be done on the fistula arm. Tight garments, sudden jerky movements to be avoided. A person can carry on normal day to day gentle activities.

WHAT ARE ADVANTAGES OF A FISTULA AND WHAT RULES ARE TO BE FOLLOWED?

In a AV fistula a patients own vein and artery is used. Hence chances of infection, foreign body reaction is minimal to nil. It can be done under local anaesthesia . If one fistula fails over a period of months to years a second fitula can be done without much morbidity.


PERMCATH AND TUNNELLED CATHETERS WHERE DO THEY STAND AS OPTION?

A permcath or tunnelled catheter goes into the main vein to which all veins of our hand orleg enters. These cathters are easy to place, easy to handle, lasts for few months to a year and easy to get dialysis done. But kept for long they can cause severe infection and narrowing and can choke the main vein and thereby stop all options of future AV fistula or graft.

Permcath therefore should be used in patients in whom fitula or graft is not possible or has failed or patient needs immediate dialysis and has no fistula.


WHAT ARE LIMITATIONS OF AV FISTULA?

A fistula requires 6-8 weeks time to mature. Thereby it is always advisable to get an early fistula done , when the patient has deteriorating renal function and may require dialysis in 2-3 months time. Once a patient is already on dialysis if he chooses to get a fistula done, he will require an additional dialysis line for 1-2 months at least.

WHAT IS ROLE AND LIMITATION WITH AV GRAFT?

An artificial tube may be used in patients whose veins are not good for AV fistula. This graft can then be used for dialysis needle puncture. However cost, infection and foreign body reaction limits its use and should be used only in patients if fistula has failed or not possible.



SMALL DIALYSIS CATHETERS ARE EASY CAN BE REPLACED – SHOULD WE USE THEM?

Temporary dialysis lines should be used as least as possible , since they are notorious for infection and lasts only for few weeks.They go into the main vein and thereby if we choke these veins no future AV Fistula, Graft, Permcath will be available in future

  best surgeon in kolkata ----->VascularExpert - DR SHUBHABRATA BANERJEE Vascular surgeons  manage veins and arteries in every part of the body except the brain and the heart . For example, vascular surgeons handle blocked carotid arteries in the neck. They treat the problems of the aorta (a large main artery) after it leaves the heart and enters the abdomen. Branched Arch Aneurysm Repair Aneurysms along the aortic arch are rare and are the most complex to treat, largely because the arterial branches that supply blood to the brain and upper extremities are attached along the aortic arch. Is vascular surgery high risk? Like all surgeries,  vascular surgery poses some risks of complications, which increase if the patient smokes, is obese, and has other serious conditions like chronic lung disease . There is additional risk when the surgeon operates on the chest or a major blood vessel. Some top-ranked hospitals in India for vascular surgery include: All India Institute o...
