Analysis of prognostic factors of mechanical thrombectomy in patients with acute ischemic stroke with large vessel occlusion

Abstract

Objective To screen the related factors of prognosis after mechanical thrombectomy in patients with acute ischemic stroke with large vessel occlusion (AIS ⁃ LVO). Methods From January 2018 to July 2019, a total of 117 patients with AIS ⁃ LVO underwent intravascular mechanical thrombectomy (including stent thrombectomy, catheter aspiration, stent thrombectomy combined with catheter aspiration). Univariate and multivariate Logistic regression analysis were used to screen the risk factors for poor prognosis. Results Logistic regression analysis showed that the elderly ( OR = 1.062, 95%CI: 1.013-1.113; P = 0.012), the previous diabetes ( OR = 3.074, 95% CI: 1.023-9.240; P = 0.045), the high NIHSS score at admission ( OR = 1.143, 95% CI: 1.043-1.252; P = 0.004), the responsible blood vessel was vertebrobasilar artery ( OR = 11.151, 95% CI: 2.877-43.079; P = 0.000) were the risk factors of poor prognosis after mechanical thrombectomy for AIS ⁃ LVO. Conclusions Elderly, the previous diabetes, high NIHSS score and posterior circulation infarction are associated with poor prognosis in patients with AIS ⁃ LVO after intravascular mechanical thrombectomy.
