Tumescent anesthesia reduces pain associated with balloon angioplasty of hemodialysis fistulas.

We describe the use of tumescent local anesthesia during endovascular treatment of arteriovenous fistula stenosis. Using ultrasound guidance, 11 patients were hand-injected with tumescent lidocaine anesthesia around the fistula stenosis prior to endovascular therapy. All patients rated the pain experienced during angioplasty on a numeric scale (0-10). The mean balloon inflation pressure was 12 ± 3.01 atm. During angioplasty, eight patients reported pain between 0 and 2; three patients reported 4, 5, and 7 out of 10 on the pain scale. In this small series, tumescent anesthesia provided adequate pain control to perform angioplasty of arteriovenous fistulas.
