Abstract

Purpose: We present an extremely rare vascular variant in which the brachiocephalic artery, right common carotid artery, and right subclavian artery course through the right lobe of the thyroid gland.

Methods: A 54-year-old woman underwent a coronary computed tomography (CT) angiography examination with the suspicion of infective endocarditis.

Results: Unexpectedly, the distal brachiocephalic artery, the proximal right common carotid artery, and right subclavian artery had a course through the right lobe of the thyroid gland. Otherwise, the arcus aorta branching pattern was normal.

Conclusion: The supraaortic major branches seldom have intrathyroidal course. The intrathyroidal course of the right common carotid artery was described previously only in one case. But, to our best knowledge, the combined intrathyroidal course of these three major vessels has not been previously reported. Although asymptomatic, such variations may complicate lower neck procedures involving thyroidectomies and thyroid biopsies if undetected and unreported. So, the awareness of this atypical course while reporting CT examinations is crucial prior to neck interventions.

头臂动脉、右颈总动脉和右锁骨下动脉的联合鞘内路线。

目的：我们报道了一种极为罕见的血管变异，其中头臂动脉、右颈总动脉和右锁骨下动脉穿过甲状腺右叶。方法：一位54岁的女性在怀疑感染性心内膜炎的情况下接受了冠状动脉计算机断层扫描（CT）血管造影术检查。结果：出乎意料的是，头臂远端动脉、右颈总动脉近端和右锁骨下动脉有一条穿过甲状腺右叶的路线。除此之外，主动脉弓分支模式正常。结论：主动脉上大支很少有鞘内走行。右侧颈总动脉的鞘内过程以前只描述过一例。但是，据我们所知，这三条主要血管的联合鞘内过程以前还没有报道。尽管没有症状，但如果未被发现和报告，这种变异可能会使涉及甲状腺切除术和甲状腺活检的下颈部手术复杂化。因此，在报告CT检查时，对这种非典型过程的认识在颈部干预之前至关重要。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
