Abstract：Objective: To investigate the efficacy and safety of different embolization techniques in the treatment of acute middle cerebral artery M2 segment occlusive cerebral infarction. Methods: A retrospective analysis was conducted on the clinical data of 45 patients with occlusive M2 segment cerebral infarction who received mechanical thrombectomy treatment at Lishui Central Hospital from August 2018 to October 2022. The patients were divided into a direct aspiration thrombectomy group and an aspiration thrombectomy combined with stent implantation group (referred to as the combined group), and the differences in the number of thrombectomies, vascular recanalization time, treatment effectiveness, and good prognosis rate between the two groups were analyzed. Results: The average arterial puncture-recanalization time was shorter in the combined group than in the direct aspiration group [(61.7±17.4)min vs. (71.3±24.2)min, P=0.037], and the difference was statistically significant ; the number of embolizations in the combined group was less than that in the direct aspiration group [1.0(1.0, 2.0) vs. 2.0(1.0, 4.0), P=0.034], and the difference was significant difference; the efficiency of the combined group was better than that of the aspiration group (77.8% vs. 55.6%); the good prognosis rate of the combined group was better than that of the aspiration group (70.4% vs. 44.4%). Conclusion: Compared with direct aspiration thrombectomy, the combined technique of aspiration and stent implantation has a shorter time to revascularization and perhaps higher efficacy and favorable prognosis for acute M2 segment occlusion in the middle cerebral artery.
