Cerebrovascular trauma.

Significant progress has been made recently in the recognition, screening, diagnosis, and treatment of blunt cerebrovascular vascular injury (BCVI). Although controversy still exists as to optimal screening algorithms and best diagnostic modality, the vital and growing role of noninvasive imaging in identifying patients at high risk for BCVI and in characterizing the injury itself has been clearly established. There has been promising early work in stratifying BCVI patients into risk categories by initially evaluating them with high-resolution head, maxillofacial, and cervical computed tomographic examinations with the ultimate goal of maximizing diagnostic yield and enabling prompt initiation of therapy.
