Subdural haemorrhage Flashcards
Acute
Most commonly caused by high impact trauma
Presentation ranges from incidental finding to severe coma and coning due to herniation
CT: crescentic collection not limited by suture lines; hyperdense (bright); may cause midline shift
Acute management
Small/ incidental observed conservatively
Surgical options include monitoring of intracranial pressure and decompressive craniectomy
Chronic subdural haematoma
Collection of blood present for weeks to months
Ruptured small bridging veins cause slow bleeding
Presentation: weeks/months confusions, reduced consciousness or neurological defecit
CT: crescentic shape; not limited by suture lines; dark compared to the brain
Risk factors for chronic subdural
Elderly and alcoholic patients as they have brain atrophy and fragile/ taut bridging veins
Chronic management
Incidental/ small with no neurological deficit: conservative management
Confused/ neurological deficit: surgical decompression with burr holes
