Grading system modification and management of blunt aortic injury

Abstract

This study based on our modified BAI grading system indicated that Grade I BAI can be managed conservatively. Grade II injury requires close observation and repeated computerized tomography angiogram (CTA) within 48 - 72 hours. If injury appears worse on follow up imaging, surgery should be performed. Delayed repair of Grade III BAI is acceptable if associated life threatening traumatic injuries need to be addressed first.
