Abstract

Objectives: This study was conducted to describe some imaging features of arterial injury with Young – Burgess classification on CT scan in pelvic trauma. Materials and methods: From 7/2019 to 11/2020, 30 patients with pelvic fracture were diagnosed with arterial injury on CT scan and treated with DSA at Viet Duc Hospital. The characteristics of the Young - Burgess classification in pelvic fracture, location and morphology of arterial lesions on CT scan are described. Results: The most common form of pelvic injury was lateral compression (LC) in 28 patients (50% LC-II at most). There were 17 patients with lesions at 1 location and 13 patients with lesions from 2 or more locations, in which it was mainly seen in the group of patients with unstable pelvic fracture with the rate of 76,9%. Arterial injury in the study was mainly active bleeding accounting for 85,4%, encountered in most types of pelvic rupture. The number of patients with unstable hemodynamic was 19/30 patients (63.3%). In the group of LC injuries, the average volume of red blood cells transfused before the intervention was 5 units, the proportion of patients with unstable hemodynamic was 60.7%. Conclusion: Both stable and unstable pelvic fractures can cause arterial damage, however, unstable pelvis fractures had a higher rate of injury from 2 vessel sites. LC injuries were most common and were most commonly associated with lesions of the anterior branches of the internal iliac artery. Active bleeding was more common than pseudoaneurysm.
