Background Head injury is a frequent reason for admission to the emergency department. In parallel, there is a growing use of anticoagulants in an increasingly aging population, which renders this particular group of trauma patients more frequent. In several countries, including Portugal, a 24-h surveillance period followed by repetition of head computed tomography (CT) is the standard procedure for these patients. However, these recommendations have not been based on studies of prevalence of intracranial hemorrhages in control head CTs, namely in this group of anticoagulated patients. This study intends to evaluate the prevalence of de novo intracranial hemorrhages in control head CTs in anticoagulated patients. Method An observational study was carried out, which included patients admitted to Hospital de Braga between June 2017 and January 2018, victims of head injury and on anticoagulation therapy, whose admission head CT excluded intracranial hemorrhage. Results We collected a total of 201 patients, with a mean age of 81.6 years, and 57.5% of them were prescribed warfarin; 181 of these patients repeated the head CT 24 h later. Of these 181 patients, 3 (1.66%) exhibited intracranial hemorrhage in control CT, without surgical indication. All patients were followed up 1 month after the trauma, and there was no readmission requiring hospitalization, surgery or death. Conclusions In conclusion, de novo intracranial hemorrhage in control head CT of anticoagulated patients is rare. We propose that these patients may be discharged if the admission CT does not reveal intracranial hemorrhage, providing that they are accompanied by a caregiver and informed about red flags.

Introduction: Our national protocol for traumatic brain injury dictates that hypocoagulated patients with mild trauma and initial tomography scan with no intracranial traumatic changes must be hospitalized for 24 hours and do a post-surveillance tomography scan. The main goal of this study was to evaluate the clinical relevance of these measures.Material and Methods: A prospective observational study was undertaken in four hospitals. Adult hypocoagulated traumatic brain injury patients with a normal tomography scan were included. The main outcomes evaluated were rate of delayed intracranial hemorrhage, rate of admission in a neurosurgical department, rate of complications related with surveillance and rate of prolonged hospitalization due to complications. An analysis combining data from a previously published report was also done.Results: A total of 178 patients were included. Four patients (2.3%) had a delayed hemorrhage and three (1.7%) were hospitalized in a neurosurgery ward. No cases of symptomatic hemorrhage were identified. No surgery was needed, and all patients had their anticoagulation stopped. Complications during surveillance were reported in seven patients (3.9%), of which two required prolonged hospitalization.Discussion: The rate of complications related with surveillance was higher than the rate of delayed hemorrhages. The initial period of in-hospital surveillance did not convey any advantage since the management of patients was never dictated by neurological changes. Post-surveillance tomography played a role in deciding about anticoagulation suspension and prolongation of hospitalization.Conclusion: Delayed hemorrhage is a rare event and the need for surgery even rarer. The need for in-hospital surveillance should be reassessed.
