Ultrasonography-Based Thyroidal and Perithyroidal Anatomy and Its Clinical Significance.

Ha EJ, Baek JH, Lee JH - Korean J Radiol (2015)

Bottom Line: For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential.Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures.Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

ABSTRACT
Ultrasonography (US)-guided procedures such as ethanol ablation, radiofrequency ablation, laser ablation, selective nerve block, and core needle biopsy have been widely applied in the diagnosis and management of thyroid and neck lesions. For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential. However, most previous reports evaluated neck anatomy based on cadavers, computed tomography, or magnetic resonance imaging rather than US. Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures. Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

Figure 11: Transverse ultrasonography images of cervical/brachial plexus.A. Schematic drawing of cervical/brachial plexus course. B. Cervical nerve (arrowhead) passes through transverse process of vertebra between anterior and posterior tubercles. C. Nerve (arrowheads) courses between scalene anterior and scalene medius muscles, and (D) is then located in posterior cervical triangle. ASM = anterior scalene muscle, AT = anterior tubercle, LSM = levator scapulae muscle, MPSM = middle and posterior scalene muscles, PT = posterior tubercle, SCM = sternocleidomastoid muscle

Mentions: The cervical plexus is a plexus of the ventral rami of the first 4 cervical spinal nerves, and the brachial plexus is formed by the ventral rami of the lower 4 cervical and first thoracic nerves. They are easily identified as a thin, cordlike, hypoechoic structure between the anterior and middle scalene muscles on US (4464748). They first pass through the transverse process of the vertebra between the anterior and posterior tubercles, and then course between the prevertebral muscles (longus colli, longus capitis, and anterior scalene muscles) and paravertebral muscles (middle/posterior scalene, splenius cervicis, and levator scapulae muscles) deep to the sternocleidomastoid (SCM) muscle. They are subsequently located on the surface of the middle scalene and levator scapulae muscles in the posterior cervical triangle (Fig. 11) (4950).
