Objective: This study aimed to determine the long-term patency duration and rate of thrombosis of autologous arteriovenous fistulas and synthetic grafts treated with endovascular methods in a large patient population. Methods: A total of 144 arteriovenous accesses (37 radiocephalic, 51 brachiobasilic, 41 brachiocephalic, and 15 femorofemoral) from 143 patients were included in the study. A total of 304 endovascular thrombolytic treatment procedures were performed for 94 (65%) arteriovenous fistula and 50 (35%) arteriovenous graft accesses. Results: The procedural technical success rate was 98.7%. The mean follow-up duration was 32.5 (range, 3–132) months. The primary patency rates for arteriovenous fistulas and arteriovenous grafts were 78% and 78% at 6 months, 66% and 63% at 1 year, and 45% and 0% at 36 months, respectively. The assisted primary patency rates for arteriovenous fistulas and arteriovenous grafts were 82% and 84% at 6 months, 71% and 69% at 1 year, 51% and 29% at 36 months, and 30% and 1% at 60 months, respectively. The secondary patency rates for arteriovenous fistulas and arteriovenous grafts were 94% and 93% at 6 months, 85% and 85% at 1 year, 58% and 59% at 36 months, and 47% and 48% at 60 months, respectively. Conclusion: Although the primary patency durations for arteriovenous fistulas were better after endovascular thrombolytic treatment than those for arteriovenous grafts, the long-term outcomes of assisted primary and secondary patency durations after repeated procedures were similar for both types of arteriovenous accesses.

Aim: Tunneled dialysis catheters are generally not used as a primary dialysis access but as bridging therapy until a permanent dialysis access is available. However, it has been stated that long-term use may be appropriate if needed. In our study, we aimed to reveal the long-term patency rates of tunneled dialysis catheters and the frequency of catheter-related diseases in a large patient group.
Material and Method: Patients who referred to our center for tunneled dialysis catheter insertion procedure between 2017 and 2022 were retrospectively analyzed with respect of catheter patency durations. The duration between the patients’ repetitive admissions to our center due to catheter dysfunction, the cause of the dysfunction and the procedure applied to achieve the patency were noted. Kaplan- Meier survival analysis was used to calculate patency rates of catheters.
Results: 1010 procedures were performed on 464 patients who applied to our center for tunneled dialysis catheter creation or dysfunction. 309 patients were excluded from the study due to short-term follow-up or lack of data. Of the remaining 155 patients with 211 catheter sites included to the study and 467 interventional procedures data analyzed. The mean primary patency duration of the tunneled dialysis catheters was 10.50±10.25 months and the secondary patency duration was 18.00±13.77 months. The 6, 12, and 24-month patency rates of the overall tunneled dialysis catheters were 91.1 %, 83.9 % and 77.9% respectively
Conclusion: Although permanent dialysis catheters, which should not be the first choice for arteriovenous access, have associated comorbidities, they are a method with satisfactory patency rates when other access types are not suitable.
