Because treatment must be instituted during the latent period between injury and onset of neurologic sequelae, diagnostic imaging is performed based on identified risk factors (Fig. 7-55).91 After identification of an injury, antithrombotics are administered if the patient does not have contraindications (intracranial hemorrhage, falling hemoglobin level with solid organ injury or complex pelvic fractures). Heparin, started without a loading dose at 15 units/kg per hour, is titrated to achieve a PTT between 40 and 50 seconds or antiplatelet agents are initiated (aspirin 325 mg/d or clopidogrel 75 mg/d). The types of antithrombotic treatment appear equivalent in published studies to date, and the duration of treatment is empirically recommended to be 6 months.
diagnostic imaging before onset of neurologic complications while taking
Early recognition and management of these injuries is paramount because patients treated with antithrombotics have a stroke rate of <1% compared with stroke rates of 20% in untreated patients.
antithrombotics for blunt inj of carotid and vertebral art decreases stroke rates from 20 to 1%
