ABSTRACT
Objective To report our initial experience with intra-arterial thrombectomy (IAT) with stent retriever for acute ischemic stroke. Methods We conducted a retrospective review of patients with acute ischemic stroke who underwent IAT from September 2010 to August 2016. Results Forty-one patients were included; mean age was 57 years (range 29­85), and 54% were women. There were 32 anterior circulation occlusions, and 11 posterior circulation occlusions. The mean value of the National Institutes of Health Stroke Scale (NIHSS) upon admission (available in 9/41 patients) was 14 (range 6­20). Nineteen patients had favorable outcomes (modified Rankin Scale [mRS] 0­2 at 6 months), and 22 had unfavorable outcomes (mRS 3­6 at 6 months). The mortality rate was 37% (15/41). Favorable outcomes were associated with revascularization within the first 360 minutes of the onset of symptoms (p » 0.000001), and satisfactory revascularization (thrombolysis in cerebral infarction [TICI] scale 2b or 3) (p » 0.0018). Conclusion It is of paramount importance to educate stroke teams on the benefits of IAT for acute ischemic stroke and the population on identifying stroke and seeking immediate care following symptom onset.
RESUMO
Objetivo Relatar nossa experiência inicial com trombectomia intra-arterial (TIA) com uso de stent retriever em acidente vascular encefálico isquêmico (Avei) agudo. Métodos Análise retrospectiva de pacientes com Avei submetidos a TIA de setembro de 2010 a agosto de 2016. Resultados Foram incluídos 41 pacientes; a idade média foi 57 anos (intervalo 29­85), e 54% dos pacientes eram mulheres. Trombos ocluindo vasos da circulação anterior foram encontrados em 32 casos, e 11 na circulação posterior. A média do valor da Escala de Acidente Vascular Encefálico do National Institutes of Health (NIH) na admissão (disponível para 9 dos 41 pacientes) foi 14 (intervalo 6­20). Um total de 19 pacientes teve resultados favoráveis (Escala de Rankin modificada [ERm] 0­2 em 6 meses), e 22 tiveram resultados não favoráveis (ERm 3­6 em 6 meses). A mortalidade foi de 37% (15/41). Resultados favoráveis foram associados com revascularização dentro dos primeiros 360 minutos de instalação dos sintomas (p » 0.000001) e revascularização satisfatória (escala de trombólise em infarto cerebral [TEIC] 2b ou 3) (p » 0.0018). Conclusão É de suma importância educar as equipes de acidente vascular encefálico sobre os benefícios da TIA para Avei agudo, e a população, na identificação do Avei, para que seja buscado atendimento imediato após o início dos sintomas.
