摘要
颈总动脉(CCA)通常分叉为颈外动脉和颈内动脉(ECA 和 ICA)。在头颈部,颈外动脉从近端到远端发出一些前方分支:甲状腺上动脉(STA)、舌动脉(LA)和面动脉(FA)。这些分支偶尔会融合成主干,其中舌面动脉主干最为常见。在对一名 67 岁患者进行计算机断层扫描血管造影(CTA)时,记录到在 CCA 分叉近端(之前)有一条 11.3 毫米的总动脉干。该干由 STA 和 LA 融合形成,被称为甲状舌骨干(TLT)。据报道,这种干的发生率在 0.3% 到 1% 之间,是 ECA 前支最罕见的变异之一。对于外科医生和介入放射科医生来说,了解颈动脉及其分支的典型和变异解剖结构至关重要。
An ectopic thyrolingual trunk arising from the common carotid artery: a rare variant.
The common carotid artery (CCA) typically bifurcates into the external and internal carotid arteries (ECA and ICA). In the head and neck area, the ECA gives off a few anterior branches from proximal to distal: the superior thyroid artery (STA), the lingual artery (LA), and the facial artery (FA). Occasionally, these branches can fuse into trunks, with the linguofacial trunk being the most common. During a computed tomography angiography (CTA) of a 67-year-old patient, a common arterial trunk, 11.3 mm proximal (prior) to the CCA bifurcation was recorded. The trunk was formed by the STA and the LA fusion and was characterized as a thyrolingual trunk (TLT). These trunks have been reported with a prevalence ranging between 0.3 and 1% and correspond to one of the rarest variants of the ECA anterior branches. Knowledge of the typical and variant anatomy of the carotid arteries and their branches is of paramount importance to surgeons and interventional radiologists.
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.
