PURPOSE: To determine the feasibility and report clinical outcomes of @entity2045 computed tomographic (CT) angiography with 64-section multidetector CT technology in the evaluation of @entity1 sustaining penetrating @entity130 . MATERIALS AND METHODS: This HIPAA-compliant retrospective study was approved by the institutional review board and consent was waived. All adult @entity130 @entity1 who sustained penetrating @entity130 to the @entity2045 and who underwent CT angiography based on the recommendation of the attending @entity130 surgeon after the initial clinical examination were included. All studies were acquired with 64-section CT technology between April 2005 and September 2007 at our level I @entity130 center. Two radiologists in consensus retrospectively reviewed all the CT angiograms for evidence of @entity1317 . Attenuation was measured with regions of interest placed within the arterial lumen of multiple segments of the @entity2045 arteries. Hospital course and disposition were determined by reviewing the @entity1 ' medical records, with a mean follow-up of 33 days. RESULTS: This study included 59 @entity1 (54 @entity1 , five @entity1 ; mean age, 27 years). Nineteen (32%) @entity1 had the following @entity1317 at CT angiography: @entity432 (n = 7), arterial extravasation (n = 6), isolated @entity2849 formation (n = 2), isolated focal @entity850 (n = 2), occlusion and @entity2849 formation (n = 1), and focal @entity850 and @entity2849 formation (n = 1). Of these 19 @entity1 , seven underwent surgical treatment. Evaluation of the technical quality of the @entity2045 angiograms demonstrated mean attenuation values of 244 HU. In 48 (81%) of 59 @entity1 , mean attenuation values were higher than 200 HU, with four (7%) @entity1 having mean attenuation values lower than 150 HU. CONCLUSION: Upper extremity CT angiograms obtained with 64-section CT demonstrated adequate technical quality in the majority of @entity1 and performed well clinically in @entity1 with penetrating @entity130 .
