•2. 18 to 65 years of age, both genders,
•3. Brachial artery with normal duplex ultrasound (DUS) parameters,
•4. Luminal diameter of vein more than equal to 2 mm confirmed on DUS
•5. Patients willing to participate in the study and willing for regular follow up
•6. Requiring a native AVF at cubital fossa as a first access
•7. A failed distal arteriovenous fistula

•1. History of surgery on vessels at or proximal to antecubital fossa
•2. Previous AVF, AV graft at or proximal to the antecubital fossa on the ipsilateral limb
•3. Central venous stenosis or occlusion of vein detected on DUS
•4. Deep vein thrombosis or arteriopathy
•5. Vein diameter < 2.0 mm [detected by preoperative-DUS, or intraoperatively when 2 mm coronary dilator cannot be passed through cephalic vein],
•6. Recent cannulation or multiple punctures of vein 2 weeks before creation of AVF
•7. Segmental or complete occlusion of vein detected on duplex ultrasonography (preoperative) or intra-operatively detected during patency test (intraoperatively when there is inability to pass 2 mm vascular dilator into the vein and lack of backflow of blood).
•8. Peripheral arterial disease: vessels with extensive arterial disease (calcified or atherosclerosis of artery) detected on DUS prior to the surgery.
•9. Lower limb AVF
•10. Not willing to participate in the study or follow-up
