Abstract :Objectives. The aim of this study was to emphasize the importance of surgical intervention perfotmed before development of arteriovenous fistula insert ignore into journalissuearticles values(AVF); aneurysm complications . Methods. The patients were categorized  into two groups: Patients undergoing elective surgery for autogenous AVF aneurysm were defined as elective group insert ignore into journalissuearticles values(Group 1);, whereas those who underwent emergency surgery due to ruptured aneurysmal fistulas were defined as emergency group insert ignore into journalissuearticles values(Group 2);. All elective cases were evaluated by doppler ultrasonography before surgery. All patients had temporary hemodialysis catheters. In the patients with salvaged fistulas, the fistulas was rested for 1 week. A new fistula was created in patients with not salvaged fistula. Results.  A total of 31 patients insert ignore into journalissuearticles values(54.8% male, mean age: 41.2 ± 14.7 years); were in Group 1 and 7 patients insert ignore into journalissuearticles values(57.1% male, mean age: 53 ± 9.4 years); were in Group 2. Significant difference was observed between two groups in terms of fistula preservation. Salvaged fistulas were significantly higher in the Group 1 than Group 2 insert ignore into journalissuearticles values( p = 0.003);. In Kaplan-Meier curves, cumulative primary AVF patency rates at 1, 3 and 6 months were 96.3%, 81.5%, and 77.8% in Group 1 and 66.7%, 66.7%, and 66.7% in Group 2, respectively insert ignore into journalissuearticles values(log-rank; p = 0.536);. Conclusions. Consultation of these cases with a cardiovascular surgeon before they reach the rupture stage is an important condition for both the patency of the fistula and the vital risk of the patient.
