Özet: Objective: The aim of this study is to share our experience in creating arteriovenous fistulas (AVF) for hemodialysis. Material and Methods: The study included 143 AVF cases performed on 131 patients between October 2010 and October 2013. The cases were retrospectively examined in a one-year surveillance period for early and midterm postoperative results. Results: Among all, 51.9 % of the patients were malse (n=68), with a mean age of 55±12 years. In those141 procedures, 32 (24.4 %) were performed on the right arm, and 99 (75.6%) were performed on the left arm. Basilic, cephalic and antecubital veins comprised 3 (2.3%), 119 (90.8%) and 9 (6.9%) cases, respectively. Venous anastomosis was carried out in radial arteries in 98 cases (74.8 %), and in brachial arteries in 33 cases (25.2%). The patency rates were 98.5% on the tenth day, 97.7 % after 6 months, and 96.9 % after 12 months. The mean flow rate through the fistulas was 661±34 ml/min after 12 months. Conclusion: Identification of the sites of anastomosis through preoperative vascular Doppler ultrasonography at the most distal locations where target arteries and veins are wider than 2 mm, and consideration of the possibility of atherosclerosis or thrombus may increase the success rate of AVFs. A murmur or thrill indicates success of the AVF procedure. Venous dilatation with low pressure using physiological saline prior to anastomosis may increase the chance to obtain a thrill.
