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.
