A NIRS pode monitorar de forma cont\u00ednua as informa\u00e7\u00f5es fisiol\u00f3gicas vasculares intracranianas. Por ser port\u00e1til, ela pode ser utilizada \u00e0 beira do leito e no centro cir\u00fargico.  Objetivos Avaliar as poss\u00edveis altera\u00e7\u00f5es hemodin\u00e2micas cerebrais durante a endarterectomia em pacientes com estenoses maiores que 70% utilizando NIRS.  M\u00e9todos Foram avaliados 10 volunt\u00e1rios portadores de doen\u00e7a carot\u00eddea ateroscler\u00f3tica com indica\u00e7\u00e3o de endarterectomia. Ap\u00f3s a sele\u00e7\u00e3o dos pacientes, que responderam um question\u00e1rio com dados epidemiol\u00f3gicos e informa\u00e7\u00f5es referentes \u00e0 presen\u00e7a de comorbidades, a doen\u00e7a foi confirmada por m\u00e9todos diagn\u00f3sticos. No procedimento cir\u00fargico, utilizou-se a NIRS para monitoriza\u00e7\u00e3o. Foram avaliadas as vari\u00e1veis satura\u00e7\u00e3o de oxig\u00eanio (SatO2), hemoglobina total (HbT), hemoglobina reduzida (HbR) e hemoglobina oxigenada (HbO) nos tr\u00eas tempos cir\u00fargicos pr\u00e9-, trans e p\u00f3s-clampeamento carot\u00eddeo. Utilizou-se p &lt; 0,05 como n\u00edvel de signific\u00e2ncia.  Resultados A avalia\u00e7\u00e3o dos resultados obtidos por meio das medidas registradas pela NIRS permite afirmar que HbR e SatO2 variam ao longo das etapas da cirurgia. Durante o clampeamento, a vari\u00e1vel HbR mostra valores mais elevados que nas outras duas etapas da cirurgia. Por outro lado, a vari\u00e1vel SatO2 mostra redu\u00e7\u00e3o durante o clampeamento.  Conclus\u00f5es A NIRS \u00e9 um m\u00e9todo vi\u00e1vel e aplic\u00e1vel de monitoriza\u00e7\u00e3o intracerebral, n\u00e3o invasivo e em tempo real, durante a endarterectomia carot\u00eddea, capaz
