title: Traumatic interhemispheric subdural haematoma: Study of 35 cases.
abstract: The clinical and radiological findings, management, and outcomes in 35 patients with traumatic interhemispheric subdural haematoma (ISH) were reviewed retrospectively. Twenty-five patients had favourable outcomes and 10 had poor outcomes. All patients were treated conservatively for ISH. Univariate analysis found that the Glasgow Coma Scale (GCS) score (p < 0.001), hypovolemic shock (p = 0.018), skull fracture (p = 0.008), convexity or posterior fossa subdural haematoma (p = 0.008), and subarachnoid haemorrhage (SAH) were correlated with outcome (p < 0.001). Multivariate analysis showed that GCS score (p = 0.031; odds ratio [OR], 0.6; 95% confidence interval [CI], 0.3-0.9) and the presence of SAH (p = 0.023; OR, 14.2; 95% CI, 1.5-138.2) were significantly related to poor outcome. This study provides important information on the clinicoradiological findings and prognoses in patients with traumatic ISH.
