The process of creating an arteriovenous fistula (AVF) is one of the most reliable vascular access methods used in dialysis treatment for patients with kidney failure. This surgical procedure connects the patient's own artery and vein, allowing blood to flow efficiently to the dialysis machine.
The AVF creation process is planned according to the patient's vascular structure and includes the following steps:
Patient evaluation involves examining the vascular structure and general health condition, selecting the appropriate artery and vein.
The surgical procedure is performed under local anesthesia, usually in the wrist or elbow area, where the artery and vein are connected.
The maturation process requires waiting four to six weeks for the fistula to strengthen and expand. During this period, heavy lifting should be avoided, and the area should be protected.
The fistula is long-lasting and can be used repeatedly. It has a lower risk of infection compared to other vascular access methods. High blood flow ensures more efficient dialysis treatment.
Fistula care includes keeping the area hygienic and monitoring for signs of infection. Regular check-ups should be conducted to detect blockages or bleeding, and excessive pressure should not be applied to the fistula area.
Possible complications include blockage or blood clot formation, bleeding or aneurysm development, and a prolonged maturation process.
The fistula is considered one of the most reliable methods for dialysis patients. With proper care and regular check-ups, it can be used safely for many years.
