Outcomes After Intracranial Rescue Stenting for Acute Ischemic Stroke

Background In cases of failed recanalization despite modern mechanical thrombectomy (MT) techniques, intracranial rescue stenting (RS) may be beneficial. However, outcomes and complications RS relative to the natural history ongoing emergent large vessel occlusion are unknown. To evaluate whether for after MT achieves superior persistent occlusion. Methods Patients from Stroke Thrombectomy Aneurysm Registry who underwent 2014 2019 were analyzed. For outcome comparisons, patients screened inclusion/exclusion criteria 3 major randomized, controlled trials. Results Over 5 years, 2827 thrombectomy, which 120 required revascularization. resulted in reperfusion (Thrombolysis Cerebral Infarction≥2B) 85.8%. Good 90‐day clinical (modified Rankin scale 0–2) achieved 33.9% patients. Inclusion/exclusion was met 50 MR CLEAN (Multicenter Randomized Clinical Trial Endovascular Treatment Acute Ischemic Netherlands), 64 ESCAPE (Endovascular Small Core Proximal Occlusion Stroke), 45 DAWN (DWI or CTP Assessment With Mismatch Triage Wake‐Up Late Presenting Strokes Undergoing Neurointervention). Of meeting trial criteria, 40.8% cohort modified 0–2 versus 19% medical arm ( P <0.001) 27% 13% =0.04). There no difference =0.15). Symptomatic hemorrhage not significantly increased compared with =0.06), but DAWN. Conclusion This retrospective registry suggests that trial‐eligible yields improved over revascularization, significant increase hemorrhagic events early windows comparable successful at intermediate timeframes.
