Abstract

PURPOSE

Given the abundance of arteries in the neck, a significant risk of puncturing arteries exists when performing a brachial plexus block. Therefore, it is important to confirm the presence of arteries when performing a brachial plexus block via the interscalene approach. This study aimed to investigate the frequency and variations of arteries in the interscalene region in healthy Japanese adults using ultrasonography.

METHODS

This is an observational study at a university hospital. We analyzed videos of the brachial plexus recorded in another study using an ultrasound device and then investigated the frequency of the presence of arteries and the location of arteries in the interscalene region.

RESULTS

Among 68 cases, 48 (70.6%) had one or more arteries in the interscalene region (63 arteries in total). The artery frequency on the ventral side of the 5th cervical nerve (C5), between C5 and the 6th cervical nerve (C6), between C6 and the 7th cervical nerve (C7), between C7 and the 8th cervical nerve (C8), and on the dorsal side of C8 was 19.1%, 1.5%, 35.3%, 29.4%, and 7.4%, respectively. The artery frequencies between C6 and C7 and between C7 and C8 were higher than those between C5 and C6 and on the dorsal side of C8.

CONCLUSION

Interscalene observations using ultrasound devices revealed a high artery frequency, with numerous topographic variations.

摘要

目的

鉴于颈部动脉丰富，在进行臂丛神经阻滞时存在穿刺动脉的重大风险。因此，在通过肌间沟入路进行臂丛神经阻滞时确认动脉的存在非常重要。本研究旨在使用超声检查调查健康日本成年人肌间沟区域动脉的频率和变异情况。

方法

这是一项在大学医院进行的观察性研究。我们分析了另一项研究中使用超声设备记录的臂丛神经视频，然后调查了肌间沟区域动脉的存在频率和动脉位置。

结果

在68例病例中，48例（70.6%）在肌间沟区域有一条或多条动脉（总共63条动脉）。第5颈神经（C5）腹侧、C5与第6颈神经（C6）之间、C6与第7颈神经（C7）之间、C7与第8颈神经（C8）之间以及C8背侧的动脉频率分别为19.1%、1.5%、35.3%、29.4%和7.4%。C6与C7之间以及C7与C8之间的动脉频率高于C5与C6之间以及C8背侧的动脉频率。
