Impact of intracranial self-expanding stents in the treatment of acute ischemic stroke: efficacy and limitations: Table 1

Abstract

In recent years, endovascular self-expanding stents have become a viable option for neurointerventionalists treating acute ischemic stroke. Timely intervention for stroke could mean the difference between complete recovery and significant morbidity or death. Since 2006, a handful of clinical trials have demonstrated the potential of self-expanding stents in dependably achieving quick revascularization. These devices are expanding in utilization as new designs offer greater procedural flexibility and better clinical results. We discuss these clinical investigations, focusing on the procedural capabilities and limitations of each self-expanding stent design.

Stenting from the Vertebral Artery to the Posterior Inferior Cerebellar Artery

“…3,4 In some circumstances, operators use those devices beyond the indications for use in the device manual. 5 In particular, the use of stent devices in small intracranial vessels of Յ2-mm diameter is still controversial.…”

Effectiveness of Mechanical Endovascular Thrombectomy in a Model System of Cerebrovascular Occlusion

“…6 This technique is now being evaluated in several ongoing clinical trials. 7,8 Sonographically driven waveguides have been used for thrombus-ablation applications in the peripheral vasculature. 9,10 In the present work, this concept is expanded to the ablation of cerebrovascular occlusion, in which the vessel geometry is more complex and tortuous.…”

Permanent implantation of the Solitaire device as a bailout technique for large vessel intracranial occlusions

“…However, there is little information on outcomes when permanent stent placement is employed. In one series, 4/18 patients underwent permanent Solitaire placement and TICI grade 3 flow was restored 10. There are additional reports of permanent placement, including one series involving 6/50 treated patients,10 and another with 5/18 treated patients 19.…”

These studies do not discuss the techniques, indications, or outcomes after permanent stentriever implantation.…”
