Wallstents and Craggstents in Hemodialysis Grafts and Fistulas: Results for Selective Indications

Angioplasty with stent graft versus bare stent for recurrent cephalic arch stenosis in autogenous arteriovenous access for hemodialysis: A prospective randomized clinical trial

“…23 Stents are therefore usually reserved for particularly difficult situations, including residual stenosis of Ͼ30% after balloon dilatation, recurrent stenoses that occur Յ6 months of balloon dilatation, or for failure of balloon dilatation. 4,7,24 Even so, the use of stent grafts for AVAs is still not common.…”

“…3 Bare stents have been used to improve AVA patency for the last 20 years. 4 No prospective studies have been done on endovascular intervention for central vein stenosis or occlusion, but bare stents have demonstrated better patency rates than PTA alone in most studies. 5 Even after stent placement, neointimal hyperplasia is still the major reason for restenosis.…”

Stent Explantation From an Arteriovenous Fistula for Hemodialysis: A Case Report

“…Only a few studies described stent placement in native arteriovenous fistulas and in only a small number of patients. 1,[13][14][15] Turmel-Rodrigues and colleagues 18 suggested surgical repair for lesions located less than 10 cm from the arteriovenous anastomosis after unsatisfactory balloon dilatation. Other authors reported various techniques to clear the adherent thrombus-like catheter aspiration 19,20 Petel and colleagues 21 placed 26 wallstents at the venous anastomosis with initial success of 100%.…”

The Role of Stent Deployment for Central and Peripheral Venous Stenosis in the Hemodialysis Access

“…One of the main controversial issues is the use of stents for peripheral stenoses that fail balloon angioplasty in the presence of an available surgical option. Some evidence (6,32,49) suggests that the mean interval to recurrence can be increased significantly after stent deployment for stenoses recurring in a peripheral vein within six months of a balloon angioplasty. In one study, the mean interval between percutaneous interventions required to maintain patency doubled after stent deployment (49).…”
