Objective To summarize the clinical characteristics of patients with acute posterior circulation large artery occlusive stroke within 6 hours via endovascular therapy and analyze the risk factors for poor prognosis.
Methods Clinical data of 43 patients with acute posterior circulation large artery occlusive stroke within 6 hours from January 2017 to June 2023 in the Department of Neurosurgery of the Affiliated People's Hospital of Jiangsu University were collected. The baseline data, the vascular recanalization rate, symptomatic intracranial hemorrhage rate, 90 d good prognosis modified Rankin Scale (mRS) score≤2 rate, and mortality were analyzed retrospectively. Univariate and multivariate Logistic regression analyses were applied to analyze the risk factors associated with poor prognosis (mRS score>2).
Results After endovascular treatment, successful revascularization was achieved in 34 cases, and 4 cases developed symptomatic intracranial hemorrhage. At the 90-day follow-up, 20 patients had good outcomes, 12 had poor outcomes, and 11 died. Univariate analysis suggested that there was a statistically significant difference in preoperative NIHSS scores between the two groups (P < 0.05). Binary logistic regression analysis showed that a high preoperative NIHSS score was an independent risk factor for poor prognosis.
Conclusion Early endovascular treatment can significantly improve the revascularization rate and prognosis of patients with acute posterior circulation large artery occlusion stroke. Preoperative NIHSS score can be used as an independent influencing factor to predict the prognosis of patients.
