Summary Background Landmark‐guided internal jugular vein cannulation is difficult for pediatric patients but useful, especially when ultrasound equipment is unavailable. Therefore, it is important to define the adjacent anatomic characteristics of the pediatric internal jugular vein. Methods In 210 children the course of the internal jugular vein, and common carotid and vertebral arteries was measured from the level of the cricoid cartilage to the supraclavicular area using ultrasound. Results From the level of the cricoid cartilage to the supraclavicular area, vessel diameter increased with internal jugular vein increasing by 12%, and common carotid and vertebral arteries increasing by 5% each. From the level of the cricoid cartilage to the supraclavicular area, the number of patients with a medial common carotid artery position relative to the internal jugular vein increased, whereas those with a lateral position decreased; the number of patients with nonoverlapped common carotid artery‐internal jugular vein increased, and those with totally overlapped decreased. In contrast, the overlapping status of vertebral artery‐internal jugular vein changes oppositely. More than 97.14% of the vertebral artery lies lateral to the internal jugular vein at these levels. The minimal vertebral artery‐internal jugular vein depth decreased from 0.46±0.20 to 0.37±0.19 cm. The angle from the internal jugular vein line to the horizontal line of the body was 83.35±9.04 degrees. Conclusion The common carotid artery and internal jugular vein are farther apart as one moves down the neck, whereas the vertebral artery and internal jugular vein are getting together. Additionally, the diameter of the internal jugular vein increased.
