A retrospective, single Australian center review of 300 patients who had blunt cerebral vascular injuries found:
-9.8% had an inpatient CVA
-Most occurred in first 72 hours
-Those receiving no anti coagulation or antiplatelets had 28% CVA incidence.
-Those treated had a 3.6% CVA incidence (anti platelets were better than anti coagulation)
-Carotid artery injury was less common than vertebral artery but had higher frequency of CVA
-associated factors: low GCS, rib fractures, severe trauma
Take away: non-treatment of blunt cerebral vascular injuries had higher inpatient stroke risk. Antiplatelet agents such as aspirin and Clopidogrel performed better than anticoagulants
