Mechanical thrombectomy with Solitaire AB stent for acute ischemic stroke: comparison between cardioembolic and large artery atherosclerotic stroke / 国际脑血管病杂志

ABSTRACT

Objective To compare the outcomes of Solitaire AB stent mechanical thrombectomy for the treatment of large-artery atherosclerotic stroke (LAA) and cardioembolic stroke (CES).Methods Acute ischemic stroke patients treated with Solitaire stent retriever device were enrolled retrospectively. They were divided into either a LAA group or a CES group according to the etiology. The outcomes in both groups were compared. Multivariate logistic regression analysis was used to determine the independent risk factors for poor outcome (defined as the modified Rankin Scale score > 2) at 90 d after onset. Results A total of 39 patients were enrolled in the study. There were 18 patients in the LAA group (49. 2％), 6 (33. 3％) had good outcome at 90 days; there were 21 patients (50. 8％) in the CES group, 9 (42. 9％) had good outcome at 90 days. There was no significant difference in the the good outcome rate at 90 days in both groups (P = 0. 223). Multivariate logistic regression analysis showed that only age was independently associated with poor outcome (odds ratio 1. 107, 95％ confidence interval 1. 016-1. 206; P = 0. 047), and stroke etiology subtype was not independently associated with poor outcome (odds ratio 0. 671, 95％ confidence interval 0. 078- 5. 743; P = 0. 716). Conclusions There was no significant difference in the clinical outcome between the patents with LAA and CES who received mechanical thrombectomy with Solitaire AB stent.
