Arteriovenous Fistula Aneuryms Seen More Frequently at Brachial Region in End Stage Renal Failure Patients

Abstract

Objective: The aim of this study is to evaluate the aneursysm developing in arteriovenous fistula's (AVF) in end stage renal failure (ESRF) patients and to emphasize the importance of using the distal portions of extremities for AVF operations as possible. Material and Methods: Between January 2006 and January 2011 200 patients who have ESRF disease had 232 AVF operations. AVF operation conducted 113 (56%) of the patients were male and 87 (44%) were female. 17 (62%) of the patients were male and 10 (38%) of the patients were female who had anuerysm developed. Patients evaluated according to their sex, age, ESRF duration, AVF localizations. Results: The mean age of male patients was 41.50 ± 16.53, and female patients was 43.37 ±17.65 who had aneurysm in AVF's. The mean duration ESRF of male patients was 53±26 months and female patients was 56 ± 24 months. AVF localizations of 27 patients who had aneurysms are; right radial AVF 2 (7%), right high AVF 2 (7%), right brachial AVF 8 (29%), left radial AVF 1 (3%), left high radial AVF 5 (18%), left brachial AVF 9 (33%). The mean fistula flow of the male patients was 1332 ± 411 mL/min and female patients was 1117 ± 326 mL/min. Aneurysm developed 17 (15%) in 113 male patients, 10 (11%) in 87 female patients. High output cardiac failure developed 2 (11%) in 17 aneurysm developed male patients, 1 (10%) in 10 aneurysm developed female patients. Conclusion: Aneurysm developed significantly more in brachial region compared to forearm. It is the forearm if feasible vessels recieved to be preferred for AVF operation having regard the risk of aneursym development. Copyright © 2011 by Türkiye Klinikleri.
