Preoperative predictive factors for surgical and functional outcomes in XXXX .

BACKGROUND: @entity6087 ( @entity6087 ) is a frequently encountered @entity558 , especially in the elderly. We investigated predictive factors for surgical and functional outcomes after @entity937 ( @entity937 ) surgery. METHODS: All @entity1 with @entity6087 treated by @entity937 between January 2012 and December 2014 were included in this study. All @entity1 were classified by symptom, clinical grade, time, location, @entity1410 density, midline shift, and other characteristics. Pre- and postoperative CT evaluation was performed at 0, 3, and 6  months. Clinical grades were classified as described in Markwalder et al. Surgical and clinical outcomes were evaluated with the brain expansion rate and modified Rankin Scale (mRS). Brain expansion rate was calculated as the ratio between post- and pre-operative @entity1410 thickness. Recurrence was defined as the occurrence of symptoms and @entity1410 on CT within 6  months. RESULTS: This study included 130 @entity1 over 2  years. Among the variable parameters, young age (<75), iso-density of @entity1410 on CT, and short duration from symptom to surgery were correlated with good brain expansion. @entity1 with good brain expansion had fewer recurrences. In terms of mRS, young age, iso-density, and good clinical grade were correlated with good functional outcomes. CONCLUSIONS: Clinicians should be more aware of general conditions and medical problems, especially in elderly @entity1 . Membranectomy should be considered in @entity1 with a long duration of symptoms or hypo-dense @entity1410 to promote good brain expansion and good mRS scores.
