Currently, there is no evidence from randomized control trials to show the safety and effectiveness of MT in patients with posterior circulation stroke. This study was to evaluate the treatment outcomes of MT in posterior circulation stroke patients enrolling in our hospital during 2010 to 2020.<\/jats:p><jats:p>\n          Materials and Methods\u2003Between January 2010 and December 2020, 66 patients with acute posterior circulation stroke underwent MT. Data collected and analyzed included demographics, comorbidity, National Institutes of Health Stroke Scale (NIHSS), procedure time, site of occlusion, presence of posterior communicating artery (PCoA), endovascular technique, and modified Rankin Scale (mRS). Good clinical outcome was defined by mRS at 2 or less at 90 days after MT.<\/jats:p><jats:p>\n          Statistical Analysis\u2003Variables with normal distribution were reported with mean\u2009\u00b1\u2009standard deviation, meanwhile those with nonnormal distribution were demonstrated with median and range. Fisher's exact test for categorical variables or Mann\u2013Whitney U test for continuous variables was performed. Multivariate logistic regression analysis with binary logistic regression method was used analyze the association between the prognosis factor and good outcome. Statistical significance was defined when p-value less than 0.05.<\/jats:p><jats:p>\n          Results\u2003The mean age of patients was 65.2 years with male predominance. The median NIHSS was 18.5. Successful recanalization (modified thrombolysis in cerebral infarction 2b-3) was achieved in 61\/66 cases (92.42%) and postprocedure symptomatic intracerebral hemorrhage occurred in 5\/66 cases (7.60%). Successful recanalization with good clinical outcome was obtained from 30 of 61 cases (49.18%); it was also associated with distal basilar artery occlusion (p\u2009=\u20090.035) and PCoA patency presence (p\u2009=\u20090.024). Our study showed the correlation between good treatment outcomes with initial NIHSS less than 20, intravenous recombinant tissue-type plasminogen activator, pre-MT magnetic resonance imaging Q5 brain, and contact aspiration MT technique.<\/jats:p><jats:p>\n          Conclusion\u2003MT is beneficial to patients with posterior circulation stroke. A good clinical outcome was significantly associated with distal basilar artery occlusion and PCoA patency presence within a group of successful recanalization.<\/jats:p>","DOI":"10.1055\/s-0042-1758848","type":"journal-article","created":{"date-parts":[[2022,12,15]],"date-time":"2022-12-15T00:24:02Z","timestamp":1671063842000},"page":"606-613","source":"Crossref","is-referenced-by-count":8,"title":["Treatment
