Abstract

PURPOSE
The purpose of the study was to evaluate the relationship between the successful revascularization on the first Solitaire stent deployment and the successful revascularization on the final angiography in acute ischemic stroke.
MATERIALS AND METHODS
From February 2012 to April 2014, 24 patients who underwent Solitaire stent thrombectomy as the first thrombectomy method for treatment of acute ischemic strokes were retrospectively reviewed. When the first Solitaire stent was deployed, 9 patients showed revascularization (Group 1) and 15 patients did not show revascularization (Group 2). Revascularization immediately after the first Solitaire stent removal and on the final angiography were comparatively assessed between the 2 groups. Statistical analysis was performed by the Fisher exact test and Student's t-test.
RESULTS
The rates of revascularization maintenance immediately after the first Solitaire stent removal were 89% in Group 1 and 27% in Group 2, respectively (p = 0.009), and the rates of final successful revascularization were 100% in Group 1 and 47% in Group 2, respectively (p = 0.009). There was a statistically significant difference between the 2 groups.
CONCLUSION
Revascularization on the first Solitaire stent deployment can be a useful predictor in evaluating the success of final revascularization in the treatment of acute ischemic stroke.
