ObjectiveTo investigate patient attitudes toward acceptable levels of disability after decompressive surgery for malignant middle cerebral artery infarction, including impact of patient age, to improve process of surgical informed consent.MethodsPatients who had experienced a recent minor stroke were asked to complete a questionnaire containing 2 parts: demographic information, including patient age, sex, years of education, working status, religion, and economic status, and acceptable level of disability based on modified Rankin Scale (mRS) with corresponding illustrations to explain mRS levels.ResultsPatient age was identified as an independent determinant of the worst acceptable mRS score with a negative correlation. For nondominant hemispheric malignant infarction, the worst acceptable mRS score was significantly lower (mean ± SD 2.0 ± 1.3) for the oldest patients (>70 years old) compared with patients <60 years old (mean ± SD 3.0 ± 0.6) and 60-70 years old (mean ± SD 3.0 ± 0.8). For dominant hemispheric malignant infarction with language impairment, all age groups showed a significantly lower value for worst acceptable mRS score (mean ± SD 1.8 ± 1.1 for patients <60 years old, 1.8 ± 1.2 for patients 60-70 years old, and 1.0 ± 1.4 for patients >70 years old).ConclusionsPatients showed different attitudes toward disability according to their age. Patients >70 years old showed the lowest worst acceptable mRS score after surgical treatment of malignant infarction. Language impairment with dominant hemispheric infarction further decreased the worst acceptable mRS score.Copyright © 2018 Elsevier Inc. All rights reserved.
