Abstract：To investigate the effect of one-stage stent implantation on the prognoses of patients with acute posterior cerebral large artery occlusive infarction after failure of mechanical thrombectomy. Methods Of 186 patients with acute posterior cerebral large artery occlusive infarction who were treated with stent extraction alone or combined with aspiration thrombus from January 2016 to June 2018, 146 patients had occlusive artery recanalization and other 40 had poor blood flow recovery. Of these 40 patients with poor blood flow recovery, 28 patients received one-stage stent implantation (stent group), and 12 received only basic antithrombus therapy (non-stent group). Results The recanalization rate of stent group (75.00%) was significantly higher than that (0%) of non-stent group (P<0.05). The rate of good prognosis in stent group (64.29%) 90 days after stent implantation was significantly higher than that (8.33%) in non-stent group (P<0.05). The mortality (21.43%) of stent group 90 days after stent implantation was significantly lower than that (83.33%) of non-stent group (P<0.05). There was no significant difference in the incidence of symptomatic intracranial hemorrhage between stent group (7.14% ) and non-stenting group (16.67% ; P>0.05). Conclusions As a remedial treatment for the failure of mechanical thrombectomy for patients with acute posterior cerebral large artery occlusive infarction, one-stage stent implantation has higher recanalization rate, fewer complications and better prognosis.
