Summary

Results of the Warfarin—Aspirin Symptomatic Intracranial Disease [WASID; NCT00004728] study suggested that patients with stroke as their qualifying event and a 70% to 99% stenosed lesion had a 1-year stroke rate of 22.5%. The objective of a study was to compare the safety and efficacy of endovascular revascularization for intracranial atherosclerosis to determine if it is possible to reduce the risk of stroke that was seen in the WASID study.
