目的：探讨老年闭合性脑外伤致外伤性脑梗死的临床特征。

方法：回顾性分析2011 年1 月—2017 年10 月北京市第一中西医结合医院脑病科收治的11 例老年闭合性脑外伤致外伤性脑梗死患者的临床资料。

结果：11 例符合病例选择标准的老年患者中，男性6 例，女性5 例；平均年龄为78.9 岁（范围：61 ～ 95 岁）。闭合性脑外伤至外伤性脑梗死的平均间隔时间为30 h（范围：2 ～ 69 h）。格拉斯哥昏迷指数评分：3 ～ 8 分者2 例，9 ～ 12 分者3 例，13 ～ 15 分者6 例。格拉斯哥预后评分：3 例为1 分，1 例为2 分，3 例为3 分，1 例为4 分，3 例为5 分。中至重度以上残疾发生率为45.5%（5/11），死亡及中至重度以上残疾发生率为72.7%（8/11）。

结论：老年闭合性脑外伤后易发生外伤性脑梗死，其临床症状严重，致残率和死亡率高，且缺乏特异的有效治疗手段。充分认识老年闭合性脑外伤致外伤性脑梗死的临床特征，对于预防和及时诊断该病以及改善其预后具有重要意义。

Objective: To explore the clinical characteristics of cerebral infarction caused by closed traumatic brain injury in elderly patients.

Methods: The clinical data of 11 elderly patients with traumatic cerebral infarction caused by closed traumatic brain injury in Department of Encephalopathy, Beijing First Hospital of Integrated Chinese and Western Medicine from January 2011 to October 2017 were retrospectively analyzed.

Results: Among 11 eligible elderly patients, 6 were males and 5 were females. The average age was 78.9 (range: 61-95) years old. The average interval between closed traumatic brain injury and posttraumatic cerebral infarction was 30 (range: 2-69) hours. The Glasgow Coma Scale score was 3-8 points in 2 patients, 9-12 points in 3 patients, and 13-15 points in 6 patients. The Glasgow Outcome Scale score was 1 point in 3 patients, 2 points in 1 patient, 3 points in 3 patients, 4 points in 1 patient, and 5 points in 3 patients. The incidence rate of moderate to severe disability was 45.5% (5/11), and the incidence rate of death and moderate to severe disability was 72.7% (8/11). 

Conclusion: The elderly patients are prone to traumatic cerebral infarction after closed traumatic brain injury, with severe clinical symptoms, high disability and mortality, and lack of specific and effective treatment. To fully understand the clinical characteristics of traumatic cerebral infarction caused by closed traumatic brain injury in elderly patients is of great significance for the prevention and timely diagnosis of this disease and the improvement of its prognosis.
