Abstract
BACKGROUND: Surgery for elderly patients with acute subdural hematomas (ASDH) is controversial, because postoperative mortality rates are reported to be high and long-term outcomes unknown. Thus, we aimed to describe midterm and long-term mortality rates of elderly patients operated for an ASDH. METHODS: We reviewed all consecutive ≥75-year-old patients operated on for an ASDH between 2009 and 2012. We recorded data on preadmission functional status (independent or dependent) and use of antithrombotic medication. Patients were followed up a median of 4.2 years (range, 2.5-6.4 years). RESULTS: Forty-four patients were included. The majority of the patients (70%) were independent and taking antithrombotic medication (77%). Independent patients had a 1-year mortality of 42%, compared to 69% for dependent patients; 56% of patients taking antithrombotics and 30% of those without antithrombotics died within the first postoperative year. All patients with an admission Glasgow coma scale score of 3-8 died within the first postoperative year, if they used antithrombotics or were dependent before the injury. Of all 1-year survivors, 77% were alive at the end of follow-up. CONCLUSION: In this first surgical case series of 75-year-old or older patients with ASDH, the overall mortality rate appears to be relatively low, especially for preoperatively conscious and independent patients without antithrombotic medication. Patients alive at 1-year after surgery had a life expectancy comparable to their age-matched peers. The prognosis seems to be detrimental for preoperatively unconscious patients who were functionally dependent or used antithrombotic medication before the injury.
