Abstract:
Objective:To investigate the efficacy and safety of endovascular treatment (EVT) in patients with acute ischemic stroke due to acute primary medium vessel occlusion (MeVO).Methods:Patients with primary MeVO received EVT in the stroke center of Jining First People's Hospital from January 2019 to January 2022 were enrolled retrospectively. MeVO was defined as occlusion of M2/M3 segment of middle cerebral artery, A2/A3 segment of anterior cerebral artery and P2/P3 segment of posterior cerebral artery. The symptoms, vascular recanalization and surgical complications were documented. The National Institutes of Health Stroke Scale (NIHSS) score at discharge and the modified Rankin Scale (mRS) score at 90 d after onset were followed up.Results:A total of 17 patients with primary MeVO were included, among them 16 successfully achieved vascular recanalization, 1 had distal emboli escape, and 1 had asymptomatic intracranial hemorrhage. There was significant difference in NIHSS scores before and after thrombectomy ( P<0.01). Ten patients (62.5%) had good functional outcome (mRS score 0-2), and 1 died of secondary pulmonary infection at 20 d after procedure. Conclusion:After strict risk/benefit evaluation and screening, EVT of acute ischemic stroke due to primary MeVO was technically feasible, and had good efficacy and safety.
