Upper extremity central venous obstruction in hemodialysis patients: treatment with Wallstents.

Abstract

After suboptimal angioplasty, treatment of subclavian and brachiocephalic vein stenoses with a Wallstent can provide continued use of a hemodialysis access. Close clinical surveillance and multiple reinterventions are necessary to maintain Wallstent patency.

Endovascular treatment of occlusive central venous disease: one center's experience

“…1,[15][16][17][18][19][20][23][24][25][26][27][28] Additionally, also in common with other authors, 20,21 we did not observe superior patency in angioplasties with stents. Notwithstanding, our results differ with …”

“…This could reduce the intimal hyperplasia response, reducing restenosis rates after angioplasty. 27 Kundu 32 published a study in which shorten or fracture, and their use may impede future endovascular procedures or surgery. Furthermore, it is already evident that all stents can provoke intimal hyperplasia, leading to recurrent stenosis and multiple interventions to maintain patency.…”

“…Patency can vary from 72 to 100% at 3 months, through 55 to 100% at 6 months to 56 to 97% at 12 months. 20,[23][24][25][26][27][28] To our knowledge, to date there have been no prospective controlled studies comparing angioplasties with and without stents for treatment of COVD. In a retrospective study published by Bakken et al in 2007 20 and comparing angioplasties with and without stents, the authors showed that there were no significant differences in patency results between angioplasties with and without stents ( Table 3).…”

Axillofemoral Fistula for Hemodialysis Access

“…Therefore we have to utilize all the interventional radiological methods for SVC outflow site repair before the decision on its unfitness. Surgical repairs in SVC central veins region are usually not possible due to extreme operating and complication rate risk [16][17][18][19] . Thorough preoperative vessel evaluation and the stable hemodynamic and coagulative condition of the patient are the basic prerequisites to prevent fistula failure 7,20,21 .…”

Treatment of inferior vena cava obstruction in hemodialysis patients using Wallstents: early and intermediate results.

“…Veselyet aJ. [12] evaluatedthe effectivenessof Wallstentsin treatingsubclavianandbrachio cephalic vein obstruction after unsuccessful angioplasty in hemodialysispatients.Thesere searchers found that Wallstents could be effec tive in salvaging hemodialysis access but that reintervention wasoftennecessary to preserve stent patency. Our experience indicates that re intervention may often be necessary to pre servepatency in Wallstents placed in the NC aswell.…”
