Abstract

Introduction & Objective: The object of this study was to determine the relationship between outcome (assessed by Glasgow Outcome Scale) and recurrence in chronic subdural haematoma (CSDH). Materials & Methods: Eighty-two consecutive patients who underwent surgery for CSDH were included in this study. Results: The relationship between the following variables and CSDH recurrence was studied: sex; age; history of trauma; Glasgow Coma Scale (GCS) at the time of admission (stage 1: GCS>12, stage 2: GCS: 8-12, stage 3: GCS<8); interval between head injury (when a history of trauma was present) and surgery; presence of a midline shift on CT scans; presence of intracranial air 7 days after surgery; haematoma density; haematoma width; presence of brain atrophy; and Glasgow Outcome Scale (GOS, both quantitative and non-quantitative) at the time of discharge. Throughout the analysis, P<0.05 was considered statistically significant. The results showed lower GCS (P<0.001), higher GOS (P<0.001), presence of intracranial air 7 days after surgery (P=0.002), and a high density haematoma (P<0.001) were significantly associated with recurrence of CSDH. Conclusions: It was concluded that GOS is related with recurrence in CSDH.
