Platelet Inhibitor Treated Patients With Head Injury Trauma Meeting NICE Criteria : is the CT-scan Mandatory ?

At the emergencies rooms, patients with head trauma meeting one of the NICE criteria, which include antiplatelet inhibitors treatment, are considered as patients with a risk of cerebral haemorrage and are taken systematically for a CT-scanner. However, there are more and more antiplatelet inhibitor's patient with minor head injury traumas seen at the emergencies room and the efficiency of this NICE criteria is controversial on litterature. This study aims to determine that the absence of no other NICE criteria than antiplatelet inhibitors is a sufficient condition to eliminate a cerebral haemorrhage for patients with head injury traumas, and conversely, that antiplatelet inhibitors treatment would not be by itself an indication for a CT-scanner.
