BackgroundBrazil is a developing country struggling to reduce its extreme social inequality, which is reflected on shortage of health-care infrastructure, mainly to the low-income class, which depends exclusively on the public health system. In Brazil, less than 1% of stroke patients have access to intravenous thrombolysis in a stroke unit, and constraints to the development of mechanical thrombectomy in the public health system increase the social burden of stroke.ObjectiveReport the feasibility of mechanical thrombectomy as part of routine stroke care in a Brazilian public university hospital.MethodsProspective data were collected from all patients treated for acute ischemic stroke with mechanical thrombectomy from June 2011 to March 2016. Combined thrombectomy was performed in eligible patients for intravenous thrombolysis if they presented occlusion of large artery. For those patients ineligible for intravenous thrombolysis, primary thrombectomy was performed as long as there was no evidence of significant ischemia for anterior circulation stroke (Alberta Stroke Program Early CT score  >6) within a 6-hour time window, and also for those patients with wake-up stroke or posterior circulation stroke, regardless of the time of symptoms onset.ResultsA total of 161 patients were evaluated, resulting in an overall successful recanalization rate of 76% and symptomatic intracranial hemorrhage rate of 6.8%. At 3 months, 36% of the patients had modified Rankin Scale score less than or equal to 2. The overall mortality rate was 23%.ConclusionOur study, the first ever large series of mechanical thrombectomy in Brazil, demonstrates acceptable efficacy and safety results, even under restricted conditions outside the ideal scenario of trial studies.Copyright © 2017 National Stroke Association.
