Basic Information

• Recruitment Status: COMPLETED
• Total Enrollment: 129 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2019-11-12
• Study Completion Date: 2020-05-19

Brief Summary

The purpose of the study is to determine the one-year post stenting outcomes in patients who were treated with the Wingspan stent on-label in the WEAVE trial. This includes both the assessment of any stroke, hemorrhage, or death, as well as assessment of delayed imaging results to determine the re-stenosis rate of the stents in these patients.

Detailed Description

The current study is a retrospective chart and imaging review of the 152 patients enrolled in the WEAVE trial to determine the one-year outcomes for these patients.

This includes both the assessment of any stroke, hemorrhage, or death, as well as assessment of delayed imaging results to determine the re-stenosis rate of the stents in these patients and the medication regimen in those patients who had symptomatic re-stenosis.

The subjects for this study are pre-defined as the 152 patients who had placement of a Wingspan stent for treatment of their intracranial artery stenosis that had symptoms of stroke and 70% or greater arterial stenosis. The study will be conducted at 24 sites in the United States. It is expected that up to 152 patients' records will be assessed for follow up data analysis. Patient's information will be included in the study if they were enrolled in the WEAVE Trial and had placement of a Wingspan stent in its on-label usage indication between 12/1/2013 and 10/31/2017. Follow up information from the patients' charts will be extracted out to the one-year interval following stenting up to December 2018.
