Results from Borgess Medical Center Intracranial Revascularization Registry}, year = {2011}, doi = {10.3174/ajnr.A2670}, publisher = {American Journal of Neuroradiology}, abstract = {BACKGROUND AND PURPOSE: The WASID study established the risk of subsequent ischemic stroke at 1 year in subjects with symptomatic intracranial atherosclerotic stenosis (70\%{\textendash}99\%) at 18\%. The efficacy of different methods of endovascular revascularization in stroke prevention still has not been established. We compared the stroke rate in our registry at 1 year following intervention with the WASID results to identify which method, if any, provides the most benefit in stroke prevention. This result from the BMC-IRR follows a previously published article comparing stent placement and angioplasty outcomes. MATERIALS AND METHODS: We maintained a nonrandomized single-center single-operator registry of consecutive symptomatic patients who underwent endovascular intracranial revascularization. Data were collected prospectively and retrospectively and analyzed retrospectively. Patients were treated with angioplasty, BMS, or self-expanding WS. To make our data comparable with that in the WASID study, we selected patients with a single lesion of 50\%{\textendash}99\% stenosis undergoing a single intervention. Data was collected on patients until symptom recurrence, repeat intervention, or 1 year postintervention, whichever occurred first. RESULTS: We found that 115 patients fit the inclusion criteria, with 38 angioplasty, 28 BMS, and 49 WS cases. For patients with 70\%{\textendash}99\% stenosis, the overall probability of stroke at 1 year postintervention was 19.3\%. The overall stroke probability per device, independent of clinical presentation, was 12.5\% for angioplasty, 20.2\% for BMS, and 24.1\% for WS. CONCLUSIONS: Compared with the WASID data, angioplasty appears to have a lower stroke rate after 1 year than medical therapy alone. However, neither stent-placement arm compared favorably with the WASID results.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/early/2011/07/21/ajnr.A2670}, eprint = {https://www.ajnr.org/content/early/2011/07/21/ajnr.A2670.full.pdf}, journal = {American Journal of Neuroradiology} }
