Various variations in the head and neck vasculature have been reported. The purpose of this report is to describe an extremely rare case of thyrolinguofacial trunk (TLFT) arising from the common carotid artery (CCA).
A 66-year-old woman with vertigo, dizziness, and heaviness in the head underwent computed tomography (CT) angiography of the neck and head region for evaluation of cerebrovascular diseases.
The TLFT originated from the anterior wall of the right CCA and was divided into the superior thyroid artery and linguofacial trunk (LFT). The LFT was divided into lingual and facial arteries. In addition, we observed fusiform dilatation of the intracranial right vertebral artery, which might have caused these symptoms.
The presence of a common trunk of the external carotid artery (ECA) branches increases the risk of complications such as bleeding and ischemia during treatment of the head and neck region, including chemoradiotherapy for oral bleeding and tongue cancer. Therefore, this is an area of significant interest across various medical specialties, including surgery, otolaryngology, and radiology. Understanding the diverse variations in the neck vasculature is expected to lead to a reduction in complications associated with various procedures.
已有多种头颈部血管变异的报道。本报告的目的是描述一种非常罕见的颈总动脉（CCA）发出的甲状腺舌骨肌干（TLFT）。
一名 66 岁女性因眩晕、头晕和头部沉重感而行头颈部 CT 血管造影术，以评估脑血管疾病。
TLFT 起源于右侧 CCA 前壁，分为甲状腺上动脉和舌骨肌干（LFT）。LFT 又分为舌动脉和面动脉。此外，我们观察到右侧颅内椎动脉呈梭形扩张，这可能导致了这些症状。
颈外动脉（ECA）分支的共同干增加了头颈部区域治疗（包括口腔出血和舌癌的放化疗）期间出血和缺血等并发症的风险。因此，这是包括外科、耳鼻喉科和放射科等多个医学专业关注的重要领域。了解颈部血管的不同变异有望减少与各种手术相关的并发症。
