Long-Term Patency Rate of Av-Fistula in Relation to Diameter of Arteriotomy 3 Mm vs <3 Mm

People who develop end stage renal disease often need dialysis in which a machine performs a basic function of kidney. 1,2 Before a patient begins dialysis treatment, a minor surgical procedure called arteriovenous (AV) fistula is done. Creating an AV fistula allows arterial pressure to enlarge the vein over time better enabling it to receive the volume of blood coming back into the body. The rising prevalence of end stage renal disease (ESRD) and the consequent impact on heathcare economics has resulted in increasing focus on delivery of vascular access care which is considered the Achilles' heel of haemodialysis. The autologous arteriovenous fistula is the acceptable gold standard mode of vascular access for haemodialysis in terms of longevity, patient morbidity and health care costs in developing country like India. Brescia-Cimino Radio Cephalic Arterio-Venous fistula (RC-AVF) at the wrist remains the vascular access of choice for haemodialysis even today 3 . Creating an autologous fistula with arteriotomy diameter of 3 mm in longitudinal axis of radial artery gives better success rate and long duration of patent functioning fistula.
