Autonomy Results in Post-Mechanical Thrombectomy Applied to Patients with Stroke a Retrospective Study

Abstract

Background: Stroke is one of the leading causes of disability and death in the world; repeated assessments of the severity of stroke are routinely collected in stroke research studies that provide an opportunity to evaluate longitudinal data on functional outcomes after discharge from the patient. Although the initial measures of stroke severity are always reported and represent the best pretreatment measure to predict the outcome and to have an initial idea of the resources necessary to implement the relevant care to the patient after stroke. Aim: To determine the degree of autonomy of patients treated with mechanical thrombectomy and to assess the degree of neurological deficit as a predictor of the degree of autonomy. Methods: This article was based in STROBE assessment criteria. This is a descriptive study of consecutive patients with either M1 or M2 branch occlusions. The sample was of 93 patients treated with mechanical thrombectomy from 2016 to March 10, 2018. Clinical outcome was measured with the modified Ranking Scale (mRS) at 90 days after stroke. About 20% of the sample had mRS at discharge between 0-2. Functional outcomes improved at 3 months so 45% of the sample reached mRS 0-2. Results: This study confirms that mechanical thrombectomy proves to be an effective treatment of acute stroke, improving the patient’s vital and functional prognosis according with the main randomized trials. Conclusion: Mechanical thrombectomy by aspiration proves to be an effective treatment of acute stroke, improving the patient’s vital and functional prognosis. The NIHSS at 24h and at 3 months measured with the NIHSS scale is a predictor of the 3-month functional outcome determined with the mRS scale.
