Traumatic Injury of Major Cerebral Venous Sinuses Associated with Traumatic Brain Injury or Head and Neck Trauma: Analysis of National Trauma Data Bank.

backgroundThe natural history and epidemiological aspects of traumatic injury of major cerebral venous sinuses are not fully understood. We determined the prevalence of traumatic injury of major cerebral venous sinuses and impact on the outcome of patients with traumatic brain injury, and/or head and neck trauma.

methodsAll the patients who were admitted with traumatic brain injury or head and neck trauma were identified by ICD-9-CM codes from the National Trauma Data Bank (NTDB), using data files from 2009 to 2010. NTDB represents one of the largest trauma databases and contains data from over 900 trauma centers across the United States. Presence of thrombosis, intimal tear, or dissection (traumatic injury) of major cerebral venous sinuses was identified in these patients by using Abbreviated Injury Scale predot codes. Admission Glasgow Coma Scale (GCS) score, Injury Severity Score (ISS), In-hospital complications, and treatment outcome were compared between patients with and without traumatic injury of major cerebral venous sinuses.

resultsA total of 76 patients were identified with traumatic injury of major cerebral venous sinuses among 453,775 patients who had been admitted with head and neck trauma. The rate of penetrating injury was higher among patients with traumatic injury of major cerebral venous sinuses (11.8% versus 2.5%,

conclusionAlthough infrequent, traumatic injury of major cerebral venous sinuses in head and neck trauma is associated with higher rates of in-hospital mortality and discharge to a nursing home.
