Abstract

First-pass recanalization is the primary goal of technical and clinical efficacy among mechanical thrombectomy techniques. We conducted a descriptive, single-center study at Bach Mai hospital from December 2020 to June 2022 to compare the recanalization results of three strategies for first-time thrombectomy including stent-retriever, aspiration, or a combination of stent and aspiration. A total of 100 patients with acute large vessel occlusion in anterior circulation within 4.5 hours were recruited for the study. There was no statistical difference in baseline characteristics between the three groups. No statistical difference in neither first-pass recanalization rate nor clinical outcomes was found between the three techniques. First-pass recanalization rate was highest in the group using stent-retriever first. Procedure time was the shortest in the aspiration first strategy. Meanwhile, final successful recanalization was highest in the combination of stent-retriever and aspiration tubing first, leading to the highest good outcome rate. The strategy for first-pass thrombectomy should be weighed against the occlusion site and the underlying occlusion etiology.
