Abstract
Background: In clinical randomized controlled trials (RCTs), decompressive surgery (DS) for malignant middle cerebral artery (MMCA) infarcts leads to a 50% absolute risk reduction in mortality, and improves the 1-year functional outcome. The reproducibility of these results in routine practice has never been evaluated. The purpose of this study was to test the hypothesis that the results of DS for MMCA in practice are similar to those observed in the surgical group of RCTs. Methods: We prospectively included the first 31 patients who underwent DS for MMCA. They were screened based on similar criteria as in the meta-analysis. The primary outcome was a modified Rankin Scale (mRS) score of ≤4, and secondary outcomes were mRS of ≤3 and death at 1 year. Results: Thirty-one patients underwent DS for MMCA. The 1-year mRS was ≤4 in 22 patients (71.0%) and ≤3 in 16 (51.6%). Seven patients died (22.6%). Conclusion: This observational study showed that DS for MMCA in a center without previous experience provides similar results as those obtained in the surgical arm of RCTs.
