ABSTRACT: Introduction: Endovascular treatment is an effective treatment for large vessel occlusive ischemic stroke. The number of Stent Retriever passes is an important link in the strategy of endovascular treatment, and is closely related to the clinical outcome and prognosis of patients with acute ischemic stroke, but there is still a lack of unified understanding. In order to provide reference for clinical practice and related research, this paper reviewed the recent important literatures. Methods: We searched PubMed, Embase, and Cochrane databases, using the terms “stents”, “stroke” and “thrombectomy”. Priority was given to human studies. Only English language papers were accepted. Analyze the articles by title and abstract. Results: The number of Stent Retriever passes is closely related to the rate of recanalization, hemorrhagic transformation, recanalization time, surgical procedures and clinical prognosis. Along with the increase of the number of Stent Retriever passes, the vascular recanculation rate decreased successively, in turn, reduced the rate of blood vessels, 3 times may be the target vascular occlusion which should try the best of times, ≥4 times may not improve the opportunity of recanalization and not conducive to the prognosis, at the same time, increase the risk of HT and related complications occurred. Conclusion: It is necessary to avoid unplanned, additional attempts at EVT. The number of Stent Retriever passes has significant effects on the outcome of EVT of AIS in many aspects. How to better personalized EVT strategy is the focus of future research.
