Abstract

Background : To discuss and emphasize the potentially elevated risk for intracranial hemorrhage after mild head injury in patients receiving low-dose aspirin prophylaxis.
Methods : The author reviewed clinical and radiological data for four patients who underwent craniotomy or trephination for evacuation of their hematoma after mild head injury on low-dose aspirin prophylaxis.
Results : The patients included two men and two women, aged 49 to 67 years, who visited the emergency department after mild head injury between July 2008 and April 2009. All were treated with low-dose aspirin therapy(100mg/day). Their hematomas were detected from 2 days to 41 days after mild head injury. Two patients underwent craniotomy and two patients underwent burr-hole trephination for evacuation of their hematomas. In the operative findings, a bleeding tendency was showed. After operation, recurred hemorrhage was developed in all patients. One patient, who suffered from remote cerebellar hemorrhage, complained severe dizziness. Recurred hematomas were treated conservatively, and gradually resolved. Relatively their prognosis was not bed.
Conclusion : A suspicion of intracranial hemorrhage should be raised in low-dose aspirin therapy, mild head injury patients, including those who present to the emergency department with Glasgow Coma Scores of 15 and no focal neurologic deficit.
