Abstract Results of Arteriovenous Fistula without Prosthetic Usage for Hemodialysis in BMA Medical College and Vajira Hospital Waigoon     Stapanavatr         MD, FICS, M.Ed (Educational Measurement) Yuthapong  Sangpayup           MD, FICS Burapa        Karnjanabatr       MD, FICS Department of Surgery, BMA Medical College and Vajira Hospital Objectivs To determine the result of vascular access by autogenous arteriovenous fistula (AVF) for hemodialysis and to evaluate factors that may associate with the success of autogenous AVF. Study design: Descriptive study. Subjects: Chronic renal failure patients who needed hemodialysis and had permanent vascular access creation in our institution during April 2004 and March 2007. Methods: The data were retrospectively collected from medical records, operative records and computer database. Main outcome measures: The success rate of permanent vascular access using autogenous AVF. Results: During the study period; 225 patients were consulted for permanent vascular access for hemodialysis. Twelve cases had tunnel cuffed catheter (TCC) while 22 cases had inadequate medical records and were excluded. 191 cases who were operated for permanent vascular access using autogenous AVF were recruited. Mean age was 57.5 ± 13.9 years (15-91 years). 84 cases were men and 107 cases were women. 114 cases had hypertension and 119 cases had diabetes. Men had successful AVF in 90.5% which was significantly higher than 86.0% in women. Hypertensive patients had success rate of 89.5% which was not significantly different from non-hypertensive patients (94.8%). Diabetic patients had success rate of 90.8% which was not significantly different from non-diabetic patients (93.1%). Conclusion: Most of the chronic renal failure patients had successful autogenous AVF for hemodialysis, a few patients needed TCC and none needed graft. Vajira Med J 2009 ; 53 51 - 57
