Blunt cerebrovascular injury involves injury to the carotid and/or vertebral arteries sustained via generalized multitrauma or directed blunt craniocervical trauma. Stroke remains the most consequential outcome. Timely diagnosis and initiation of treatment before the development of neurologic complications has a well-established role in decreasing morbidity and mortality. This article presents evidence and controversies surrounding the optimization of diagnostic imaging for suspected blunt cerebrovascular injury. Discussion centers on the increasing reliance on multidetector computed tomography angiography for screening, considering relevant clinical criteria for determining screening. Imaging protocols, imaging findings, injury grading, pearls, and pitfalls are discussed.
钝性脑血管损伤是指因全身性多发伤或直接的钝性颅颈外伤导致的颈动脉和/或椎动脉损伤。中风仍然是最严重的后果。在神经并发症出现之前及时诊断并开始治疗，对于降低发病率和死亡率具有公认的作用。本文介绍了围绕疑似钝性脑血管损伤的诊断性影像学优化的证据和争议。讨论的重点是越来越依赖多排计算机断层扫描血管造影进行筛查，并考虑确定筛查的相关临床标准。还讨论了成像方案、成像结果、损伤分级、要点和陷阱。
