OBJECTIVE: This study attempts to document the incidence of unsuspected blunt @entity1914 (BCI) in a prospective series of consecutive blunt @entity130 @entity1 undergoing angiographic evaluation of the aorta. Previous studies have included mainly @entity1 who became symptomatic from BCI, thus documenting a "detected incidence." METHODS: During a 22-month period, all @entity1 undergoing angiographic evaluation of the aorta after blunt @entity130 who were not felt to be at increased risk for BCI were included in the screening protocol. All @entity1 initially suspected of BCI were studied outside the protocol. Angiographic evaluation of the carotid arteries was performed using nonselective contrast injections after @entity130 had been ruled out. RESULTS: The incidence of BCI among those @entity1 screened under the protocol (n = 119) was 2.5% (3 of 119). Among all @entity1 undergoing aortic evaluation at presentation (n = 171), the detected incidence of BCI was 3.5% (6 of 171). The detected incidence of BCI among all @entity1 during the study period was 0.32% (10 of 3174). No risk factors for BCI were identified beyond the severity of @entity130 that led to aortic evaluation. CONCLUSION: The incidence of BCI found in those @entity1 screened in this study, nearly 10 times the incidence of BCI in our blunt @entity130 population overall, suggests that these @entity1 represent a subgroup on which to focus screening efforts, regardless of the diagnostic tools employed. The similarity between the angiographic incidence and the detected incidence of BCI in this study argues that few BCIs remain asymptomatic. All blunt @entity130 @entity1 injured sufficiently to prompt aortic evaluation at presentation should be screened in some manner for BCI.
