The aim of this article is to utilize ultrasound to evaluate the normal cross-sectional area (CSA)of the vagus nerve (VN) in the carotid sheath. This study included 86 VNs in 43 healthy subjects (15 men, 28 women); mean age 42.1 years and mean body mass index 26.2 kg/m2. For each subject, the bilateral VNs were identified by US at the anterolateral neck within the common carotid sheaths. One radiologist obtained 3 separate CSA measurements for each of the bilateral VNs with complete transducer removal between each measurement. Additionally, for each participant, demographic information of age and gender as well as body mass index, weight, and height were documented. The mean CSA of the right VN in the carotid sheath was 2.1 and 1.9 mm2 for the left VN. The right VN CSA was significantly larger than the left VN (P < .012). No statistically significant correlation was noted in relation to height, weight, and age. We believe that the reference values for the normal CSA of the VN obtained in our study, could help in the sonographic evaluation of VN enlargement, as it relates to the diagnosis of various diseases affecting the VN.
本文旨在利用超声评估颈鞘内迷走神经（VN）的正常横截面积（CSA）。该研究纳入了 43 名健康受试者（15 名男性，28 名女性）的 86 条 VN，平均年龄为 42.1 岁，平均体重指数为 26.2kg/m2。对于每个受试者，通过超声在颈前外侧的颈总动脉鞘内识别双侧 VN。一位放射科医生在每个测量之间完全移除探头，对双侧 VN 的每个进行了 3 次独立 CSA 测量。此外，对于每个参与者，还记录了年龄、性别以及体重指数、体重和身高的人口统计学信息。右侧 VN 在颈鞘内的 CSA 平均值为 2.1mm2，左侧为 1.9mm2。右侧 VN CSA 明显大于左侧（P<.012）。与身高、体重和年龄无显著相关性。我们认为，我们研究中获得的 VN 正常 CSA 的参考值，可能有助于 VN 增大的超声评估，因为它与各种影响 VN 的疾病的诊断有关。
