Acute revascularization therapies for these patients were not tested in randomized controlled trials. The aim of this study was to evaluate outcomes of iPCAO patients who undergo endovascular treatment (EVT).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A\u00a0systematic search of MEDLINE, Web of Science, CENTRAL, Scopus (inception\u201403\/2022) was conducted for studies reporting 3\u2011month outcome, symptomatic intracranial hemorrhage (sICH) and\/or successful recanalization in iPCAO patients who underwent EVT. Random effect meta-analyses for pooled proportions were calculated.

Excellent and favorable 3\u2011month outcome proportions were 36% (95% confidence interval, CI 20\u201351%) and 57% (95% CI 40\u201373%), respectively. The 3\u2011month mortality was 9% (95% CI 5\u201313), sICH occurred in 1% (95% CI 0\u20132%), successful recanalization was achieved in 79% (95% CI 71\u201386%). No significant differences in favorable and excellent 3\u2011month outcomes, 3\u2011month mortality and symptomatic intracerebral hemorrhage were found between the groups of patients who underwent EVT and the group of patients who received best medical treatment only.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>These results support the feasibility and safety of EVT in iPCAO, but do not show an outcome benefit with EVT compared to best medical treatment.
