Background:
Stent placement in the cannulation zone of AVF is becoming alarmingly frequent and sometimes in cases where surgical management would be more appropriate. When complications arise repair can be particularly challenging. We present our experience and management of this problem.
Methods:
We report our experience on three patients (two females and one male, mean age 72) that were referred to our department for problems related to stents placed at the cannulation segments.
Results:
All patients required complex surgical interventions. In two of them maintenance of access was possible but required the use of a graft. In one complete resection of the AVF and all stents was necessary, and the patient remained on dialysis through catheter.
Conclusion:
Stent placement at the cannulation zones may complicate access management in the future and should be avoided if possible.
