Outcomes and recurrence rates in chronic subdural haematoma.
The object of this study was to determine the relationship between outcome (assessed by Glasgow Outcome Scale) and recurrence in chronic subdural haematoma (CSDH). Eighty-two consecutive patients who underwent surgery for CSDH were included in this study. 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. It was concluded that GOS is related with recurrence in CSDH.
