Long-term survival after chronic subdural haematoma

摘要: Outcome after chronic subdural haematoma (CSDH) is invariably assumed favourable: however, little data regarding long term survival (LTS) exists. One study reported excess mortality restricted to year 1, but with expected actuarial rates thereafter. We aimed determine LTS CSDH in a retrospective analysis relative from age-matched controls. Data was obtained n=155, (M:F 97:58, 69.3±2.3years). Follow-up maxima 14.19years (mean: 4.02±3.07years, median: 5.2years). Mortality in-hospital, at 6months, 1year, 2years and 5years n=13 (8.39%), n=22 (14.19%), n=31 (20.35%), n=42 (27.1%) n=54 (34.84%). significantly worse than controls (5.29±0.59years vs. 17.74±1.8years, hazard ratio [HR]: 3.52, P<0.0001). Death most frequently related pneumonia/sepsis ischemic heart disease (IHD). Median modified Rankin score (mRS) those discharged home (n=94, 60.65%) 2 [IQR: 1-3]. Discharge mRS who died 5 3-6], 4-6], 3 1-3], 4 2-5]. 1 (P=0.014). discharge (HR: 37.006, P<0.001), post-operative motor-score 0.581, P=0.0026), IHD 5.186, P=0.005), warfarin-use 5.93, P=0.036) dementia 5.39, P=0.031). No recurrences (LTR) were recorded. Although mRS=2, markedly less previously reported: peers lived 12.4years longer. greater not continued throughout prolonged follow-up. disability dependence, co-morbid risk factors for cerebral atrophy. LTR suggests that, once ultimately closed, the 'subdural space' remains closed. patients represent vulnerable group require long-term medical surveillance.
