Abstract: Objective To evaluate the efficacy and safety of mechanical thrombectomy in the treatment of acute cerebral infarction (4-6 hours).Methods From June 2015 to December 2016 in our hospital onset 4-6 hours within the time window of 187 cases of acute cerebral infarction patients were analyzed retrospectively.All patients underwent cerebral angiography to define the cause of vascular occlusion patients underwent stent thrombectomy,statistical analysis of vascular recanalization and clinical curative effect.Results After interventional therapy,M2 segment occlusion in 17 cases (12 cases recanalization),M1 segment occlusion in 58 cases (52 cases recanalization),carotid terminus occlusion (T) in 9 cases (4 cases recanalization),clinoid segment occlusion in 7 cases (1 case recanalization),complete occlusion of internal carotid artery in 15 cases (10 cases recanalization),vertebral basilar artery occlusion in 28 cases (24 cases recanalization).Occlusion of the M2 segment of patients after 1 week of treatment was significantly improved compared with preoperative (P<0.05),M1 occlusions in patients after 1 day showed a significant improvement (P<0.01),vertebral basilar artery occlusion in patients after first day showed a significant improvement (P<0.05).mRS score 1-3 after one month in patients with M2 segment occlusion accounted for 88%,M1 segment occlusion accounted for 60%,carotid terminus occlusion (T) accounted for 11%,clinoid segment of internal carotid artery occlusion accounting for 14%,complete occlusion of internal carotid artery accounted for 7%,vertebral basilar artery occlusion accounting for 39%.Conclusion It is safe and effective in the treatment of 4-6 hours time window for endovascular mechanical thrombectomy,and most of the patients can improve the clinical efficacy.
