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.

Transverse ultrasonography (US) images of anterior jugular vein.A. Anterior jugular vein can be easily collapsed by US probe, and is not visible. B. Therefore, operators should apply soft pressure to identify anterior jugular veins (arrowheads).

Figure 18: Transverse ultrasonography (US) images of anterior jugular vein.A. Anterior jugular vein can be easily collapsed by US probe, and is not visible. B. Therefore, operators should apply soft pressure to identify anterior jugular veins (arrowheads).

Mentions: The anterior jugular vein begins near the hyoid bone, and descends between the median line and anterior border of the SCM muscle. It varies considerably in size, usually inversely proportional to the external jugular vein. In most cases, there are 2 anterior jugular veins, a right and left, but occasionally only 1 vein (5960). It can be damaged when inserting the electrode or needle by a trans-isthmic approach in minimally invasive treatment. Because it is easily collapsed by the US probe, operators should apply soft pressure to identify the anterior jugular vein (Fig. 18). Although injury to the anterior jugular vein can be easily controlled by simple compression, it can disturb the procedure due to persistent oozing.
