Filter by:Anti-aggregation therapy, including treatment with low-dose aspirin (LDA) is an established risk factor for intracranial hemorrhage, including chronic subdural hematoma (CSDH); however evidence guiding the decision to continue or discontinue LDA in patients who have sustained mild head trauma with no sign of injury on CT is lacking. The investigators aim to assess whether continued aspirin treatment increases the risk of CSDH in mild head trauma patients 50 years and older who present with negative head CT. The investigators further aim to use the initial findings to refine the study design, with the goal of performing a larger, multi-institutional study in the future. Over a 12-month period, approximately 100 patients ≥50 years of age on LDA prophylaxis presenting to Hadassah's Emergency Department after sustaining mild head injury, will be examined by the neurosurgeon on call. Those who have no sign of intracranial hemorrhage at clinical or CT examination, and who meet inclusion / exclusion criteria, will be invited to participate in a randomized study. Informed consent will be obtained. Patients will be remotely randomized for continuation or cessation of LDA treatment. Follow-up CT and clinical examination will be performed 3-5 weeks after trauma. The two-proportions test will be used to assess whether there is a statistically significant difference in the rate of CSDH in patients randomized to cessation of LDA therapy and those randomized to continuation of LDA. Relationships between the explanatory the dependent variables will be explored with classical parametric and nonparametric statistical methods, including multivariate analysis, logistic regression, the two proportions test, and the independence test. Several measures of association/correlation between pairs of variables will be analyzed as well. The investigators hypothesize that continuation of LDA will not be associated with increased risk for chronic subdural hematoma, and that cessation of treatment will not be associated with a decrease in chronic subdural hematoma. The investigators further hypothesize that cessation of LDA for this period will not be associated with increased risk for clinically significant cerebrovascular, cardiovascular, thrombotic, of embolic event.
The chronic subdural hematoma is a common disease in the population over 60 years. For example, in patients over 70 years, it occurs every year 7 new cases per 100,000 people. A chronic subdural hematoma is an accumulation of blood in the intracranial space between brain membrane (dura mater) and the brain. The origin of blood in this area follows a minor brain injury, which causes the rupture of small vessels in the area. During its evolution, the volume of the hematoma increases. After a few weeks, the amount of fluid build-up can compress the brain. That's when clinical symptoms occur: persistent headaches, neurological deficits, seizures, impaired consciousness, cognitive functions (memory loss, impaired intellectual function, or hallucinations, etc.). The compression of the brain may cause impairment of consciousness resulting in more severe cases coma and death. At this stage, a neurosurgical intervention is necessary. Recurrences are numerous (15 to 25% recurrence over six months after neurosurgery). That is why in France, about 20% of medical teams administer a postoperative treatment with corticosteroids to reduce the risk of recurrence. Until now, the potential benefit of this treatment has not yet been confirmed by a clinical study. So the purpose of this research.
The project aims at investigating if treatment with the Angiotensin Converting Enzyme inhibitor Coversyl (perindopril) for 3 months after surgery for chronic subdural hematoma will decrease the risc of recurrence.
