Tratamento endovascular do acidente vascular isquêmico agudo

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Poucos pacientes se beneficiam do atual tratamento para o acidente vascular cerebral isquêmico agudo (AVCIA), incentivando o desenvolvimento de novos tratamentos.

Objetivo

Revisão sistemática da literatura sobre a eficácia e/ou segurança da trombectomia endovascular (TE) em AVCIA comparado com tratamento padrão (TP) e identificar ensaios clínicos randomizados controlados (ECR) atualmente em andamento.

Método

Buscas por ECRs foram conduzidas no Medline,Embase, International Clinical Trial Registry Platform, Clinicaltrials.gov e no ISRCTN registry (to June 15th, 2015).

Resultados

Oito ECRs publicados foram identificados, dos quais cinco mostraram superioridade do tratamento com trombectomia comparado ao TP. Dos 13 ERCs registrados, 3 foram suspensos, um não iniciou, um temstatus desconhecido e oito encerrarão recrutamento entre 2016 e 2020.

Conclusão

A evidência favorece a combinação do TP com a TE em relação ao TP somente. Os critérios de inclusão limitam o número daqueles que poderiam se beneficiar. Mais estudos são necessários para demonstrar o custo-efetividade desta intervenção.
