Abstract

The study was conducted to evaluate various imaging features and the value of multidetector computed tomography (CT) in diagnosing arterial injury in patients with pelvic trauma. From July 2019 to November 2020, a retrospective study was performed on 30 pelvic trauma patients who presented with arterial injury on CT and later underwent digital subtraction angiography (DSA) at Viet Duc Hospital. The characteristics of pelvic trauma classification, locations and morphology of arterial lesions on CT were described. The value of CT in diagnosis compared with DSA was collected and analyzed. The most commonly injured arterial branches were the internal pudendal artery and the obturator artery with the rate of 27.1%. The most common form of arterial injury was active bleeding accounting for 85.1%. There was no significant differences in the sizes of the lesions in the arterial and portal phases noticed between the positive and negative groups on DSA (p > 0.05). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CT scan were 85.7%, 64.3%, 87.8%, 60%, 80.4% in diagnosing active bleeding and 75%, 97.9. %, 85.7%, 95.9%, 94.6% in diagnosing pseudoaneurysm, respectively. The CT scan is valuable in diagnosing arterial lesions in pelvic trauma to make decisions for DSA intervention.
