The patient is referred for the first time by a nephrologist for of permanent hemodialysis access implantation .
Clinical examination of both upper limbs should confirm all of the following criteria: 1) Presence of the cephalic vein in distal third of forearm 2) Presence of the radial pulse 3) Presence of the ulnar pulse 4) Positive Allen's test 5) Cephalic vein and radial artery in distal third of forearm are not more than 2 cm apart.
Preoperative arteriovenous mapping by Doppler ultrasound confirms all of the following criteria: 1) Patent cephalic vein with a minimum diameter of 2.5 mm in distal third of forearm, with no stenosis and a minimum continuity of 15 cm 2) Patent radial artery, with a minimum diameter of 2 mm in distal third of forearm, free of stenosis and major calcifications 3) Patent ulnar artery, free of stenosis and major calcifications 4) Positive Allen's test as confirmed by retrograde flow test (patent palm arch) 5) Cephalic vein and radial artery in distal third of forearm are not more than 2 cm apart.
Patient's informed consent to participate in the study.
