Purpose: The aim of this study was to assess the long-term effectiveness of tunnelled permanent hemodialysis catheters in end stage renal insufficiency patients and to detect complications that result in catheter dysfunction. Materials and Methods: We inserted 68 permanent catheters to 40 end stage renal insufficiency patients (28 female, 10 male; average age 58,2 years, range 20-80 years) under the guidance of ultrasonography and fluoroscopy in the study period of two years. We evaluated catheter related complications retrospectively and calculated survival of hemodialysis catheters.  Results: We determined 58 long-term complications (5.2 times in 1000 catheter days) which were; 28 cases of catheter thrombosis in 10 patients (2.5/1000 days), 14 cases of catheter related sepsis in 14 patients (1. 25/1000 days), 3 cases of spontaneous extrusion of catheter in 3 patients (0.27/1000 days), 7 cases of bleeding at catheter insertion site in 6 patients (0.63/1000 days), 3 cases of inadequate blood flow in 3 patients (0.27/1000 days). The average survival of catheters were 186 days, 133 days and 164 days in primary, secondary and in total respectively. Conclusion: The native arteriovenous (AV) fistulas are the best procedure of vascular access in chronic hemodialysis. Tunnelled permanent hemodialysis catheters prove to be a good alternative for patients who can not use AV fistulas.
