This descriptive retrospective study was done to observe the different techniques of arteriovenous fistula creation for advantages and disadvantages, complications, and early and midterm patency. Fifty-three arteriovenous fistulas were created from September 2018 to August 2020 using four different techniques. Radio-cephalic arteriovenous fistula was usually the first option. Other techniques like brachio-cephalic arteriovenous fistula, radio-basilic arteriovenous fistula, and brachio-basilic arteriovenous fistula were used when the radio-cephalic fistula had thrombosed or could not be constructed due to small-sized cephalic vein in the forearm. The majority of patients (41 (77.35%)) underwent radio-cephalic fistula creation. Early patency was 38 (92.7%) in the radio-cephalic technique whereas it was 12 (100%) in the radio-basilic, brachio-cephalic, and brachio-basilic techniques combined. The midterm patency was 32 (78%) in the radio-cephalic technique, 5 (83%) in the brachio-cephalic technique, 3 (75%) in the radio-basilic technique, and 1 (50%) in the brachio-basilic technique. Radio-basilic and brachio-cephalic are alternative techniques for fistula creation after radio-cephalic depending upon the size of the basilic vein in the forearm or cephalic vein in the cubital fossa or arm. The radio-basilic technique may have advantages over the brachio-cephalic technique which need to be further evaluated. Proximal fistulas like brachio-basilic and brachio-cephalic are more commonly associated with limb edema.
