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 13: Transverse ultrasonography images of phrenic nerve.A. Schematic drawing of phrenic nerve. B. Phrenic nerve (arrowhead) lies superficial to ASM along its course. ASM = anterior scalene muscle, PN = phrenic nerve, TCA = transverse cervical artery

Mentions: The phrenic nerve originates from the C3-5 nerves, mainly from the C4 nerve. The phrenic nerve can be identified by US through the majority of its course. It descends obliquely anterior to the anterior scalene muscle deep, and immediately behind the SCM muscle, lateral to the IJV, and medial to the brachial plexus roots (Fig. 13). Because it crosses the transverse cervical artery along its course on the anterior scalene muscle, the transverse cervical artery is used as an anatomic landmark for detection of the phrenic nerve. The phrenic nerve crosses anterior to the first part of the subclavian artery on the left and anterior to the second part of the subclavian artery on the right (55).
