An arteriovenous fistula((AV) Fistula) is an abnormal channel or passage between an artery and a vein. If it is advance stage then the patient allow to access to the vascular system for hemodialysis a procedure to perform function of the kidney in the people whose kidney have failed. The fistula is developing over a period of months after the surgery.

Arteriovenous fistula symptoms & causes:

The surgical creation of an AV fistula provides a long-lasting site through which blood is removed and returned during hemodialysis. The fistula which allow person to be connected to be connected to dialysis machine must be prepared by a surgeon week or month before dialysis started. When the vein and artery are joined the vein gradually become larger and stronger creating fistula provides vascular access year longer than other type to access less complication. Dr Manish Raval is experienced deep venous thrombosis treatment in Africa and India.

Procedure in A-V fistula surgery:

(AV) Fistula Surgery – During this procedure you will place under anaesthesia thought the outpatient surgery does not require overnight hospital stay. The purpose of surgery is to connect a large vein in the arm or leg to a nearby artery. The procedure divert the portion some not all of the venous blood through the artery.

The vascular surgeon typically has done one or two surgical technique.

The basic procedure join an artery vein usually in the arm through sometimes the fistula may be placed in the leg.
Some patient with advanced vascular diseases who are week or if the vein is blocked the vascular surgeon might use an artificial graft create the fistula.

Arteriovenous fistula Risks:

The most frequent complication in hemodialysis relate to the vascular access site where needles are inserted. This can include infection around the access area or the formation of clots may block the fistula. The greatest danger is that clots may block the fistula and would have to be removed surgically. Complication from dialysis that is not directly related to vascular access. Deep venous treatment medication is may prescribed and changes in fluid intake or diet may be made to help balance fluids safely in conjunction with dialysis.

Potential risks of arteriovenous (AV) fistula creation include:

  • Infection
  • Clotting of the vessels involved
  • Narrowing of the vessels in the fistula
  • Bleeding

After surgery:

After surgery you will asked to keep the surgery site elevated. You may be prescribed pain medication, if needed. Avoid heavy lifting soon after surgery. Special exercise to strengthen the fistula.
