Abstract

Introduction: Computed tomography (CT) angiography is commonly utilized to quickly identify vascular injuries caused by blunt cervical trauma. It is often conducted alongside a cervical spine CT, based on established criteria. This study assessed the prevalence of cervical vascular injuries identified via CT angiography (CTA) in patients who had negative findings on cervical CT scans.

Materials and methods: A retrospective study was performed on patients who experienced blunt trauma from January 2020 to December 2022 and underwent both cervical CT and CTA. The sample size was determined using the formula: n = (Z^2 * P * (1 - P)) / E^2, assuming a 99% confidence interval, a 2% margin of error, and a proportion of 0.05.

Results: A total of 1,165 patients presented with acute blunt trauma to the head and neck during the study period. Out of those, 800 patients (68.7%) had negative cervical CT scans and only 5 patients (0.6%) were found to have vascular injuries on CTA, with an average age of 44.2 years. Regarding the severity of the injuries, three were classified as grade I and two as grade II. On the other hand, of the 365 patients with positive cervical CT, 44 patients (12%) had vascular injury on CTA, including 16 patients (4.5%) with grades III and IV injuries.

Conclusion: The findings of this study suggest that CTA in patients with negative cervical CT scans seldom reveals vascular injuries, with no injuries exceeding grade II. This highlights the selective utility of CTA in this patient group.

钝性外伤后颈椎CT阴性患者血管损伤的发生率。

简介：计算机断层扫描（CT）血管造影通常用于快速识别钝性颈椎外伤引起的血管损伤。它通常与颈椎CT一起进行，基于既定的标准。本研究评估了在宫颈CT扫描阴性的患者中，通过CT血管造影（CTA）发现的颈椎血管损伤的患病率。材料与方法：对2020年1月至2022年12月钝性创伤患者进行回顾性研究，并进行颈椎CT和CTA检查。样本量采用公式确定：n = (Z^2 * P * (1 - P)) / E^2，假设置信区间为99%，误差幅度为2%，比例为0.05。结果：在研究期间，共有1165例患者出现急性头颈部钝性创伤。其中800例（68.7%）患者宫颈CT扫描阴性，仅5例（0.6%）患者在CTA上发现血管损伤，平均年龄44.2岁。其中3人的伤情为1级，2人的伤情为2级。另一方面，365例宫颈CT阳性患者中，CTA血管损伤44例（12%），其中III级和IV级损伤16例（4.5%）。结论：本研究结果提示，宫颈CT阴性患者的CTA很少显示血管损伤，没有超过II级的损伤。这突出了CTA在该患者组中的选择性效用。
