Cragg Covered Stents in Hemodialysis Access: Initial and Midterm Results

Efficacy of covered stent placement for central venous occlusive disease in hemodialysis patients

“…7 Covered stents provide an interesting treatment alternative for CVOD because they have had moderate results for central venous stenosis and occlusion in hemodialysis patients, with their use reserved for suboptimal angioplasty or refractory stenosis. In 1996, Sapoval et al 16 mentioned the use of a nitinol plus Dacron-covered stent (Craig Endopro Mintec, La Ciotat, France) for in-stent stenosis of a Wallsent, with asymptomatic recurrent restenosis after 6 months. In a 2003 study, Quinn et al 11 placed six covered stents for venous outflow stenosis.…”

“…[12][13][14] The experience reported for stenotic or occlusive lesions is limited to small series. 11,[15][16][17] The aim of this study was to evaluate the efficacy and durability of covered stents in treating CVOD to restore the venous outflow, preserving a functional arteriovenous (AV) dialysis access circuit.…”

Stent graft treatment for hemodialysis access aneurysms

“…13 The different types of covered stents that have been used in endovascular treatment have been previously described. 12,[14][15][16][17][18][19] Endovascular access aneurysm repair is usually performed as an outpatient procedure, 20 and early dialysis venipuncture is encouraged to return the patient to an uninterrupted dialysis regimen. 15,17 Although not specifically designed for hemodialysis needle puncture, commercially available covered stent devices can endure repeated punctures to extend the use of the access for hemodialysis for many years (Fig 3).…”

Treatment of Central Venous Obstruction in the Dialysis Patient: Patient Considerations and Treatment Options

“…There is a small amount of literature on CS usage in the HD access circuit. Most of the literature to date has been on the treatment of graft or outflow vein aneurysms and refractory venous outflow stenoses (Ananthakrishan, Bhat, Severn, & Chakraverty, 2008;Hausegger et al, 1998;Keeling, Naughton, McGrath, Conlon, & Lee, 2008;Naoum, Irwin, & Hunter, 2006;Sapoval et al, 1996;Silas & Bettmann, 2003;Vesely, 2005). CSs for CVD have only been mentioned in two publications to date.…”

“…CSs for CVD have only been mentioned in two publications to date. Sapoval et al in 1996 mentioned the use of a nitinol plus dacron covered stent (Craig EndoproÔ, Mintec, LaCiotat, France) for a in-stent restenosis of a WallstentÔ, with asymptomatic recurrent restenosis after 6 months (Quinn, Kim, & Sheley, 2003). A study by Quinn et al in 2003 placed 6 CSs for CVD and 11 CSs for venous outflow stenoses.…”
