“…The length of the right and left LFT before splitting into the LA and the FA was 3.8 mm and 3.9 mm respectively. Troupis et al in their study mentioned that the site of emergence of the LFT was at 7.6 mm and 6.8 mm from carotid termination and the length of the LFT before division into the LA and the FA was at 3.1 mm and 3.4 mm on the right and the left sides respectively [15]. Gonzalez et al stated that the walls of the LA and the FA become very thick and tough when they came off from the LFT and that may be the probable reason for developing pseudoaneurysms in the ECA after catheterization procedures [16].…”

Trifurcation of the common carotid artery in the neck region is a rare anatomical variation. In the present study, we reported a rare case having the combination of anomalies of the bilateral high common carotid arteries trifurcation and variable origin of lower branches of the external carotid artery during routine dissection of the head and neck region of a 60-year-old male cadaver in the Department of Anatomy. Both on the left and right sides of the neck region, the common carotid artery gave off three terminal branches: internal carotid artery, external carotid artery, and ascending pharyngeal arteries. Further, we also observed the presence of bilateral linguofacial trunks (common arterial trunks) that emerged from the external carotid arteries and also the left superior thyroid artery that originated directly from the left common carotid artery. Even though the embryogenesis of the variable origin of such arterial trunks is not apparent, it is very indispensable to have sound knowledge and better comprehension of the accurate anatomical architecture of such a rare combination of carotid arterial system anomalies for correct interpretation of the vascular imaging that pave the pathway for successful execution of surgical interventions in the neck region because of its utmost clinical implication.

“…The diameters of the arteries/common arterial trunks were determined 2 mm from their origin. 5 In this cadaveric specimen, the TLFT was the first branch that arose about 4.6 mm above the carotid termination from the ventral surface of the right ECA. The length of the TLFT was 2.1 mm.…”

“…Anomalous emergence of the LA from the LFT in the submandibular region can hamper the extraoral ligation of the LA during the above surgical emergencies and further add neurovascular complications. 5 Baik et al 13 stated that LA and FA originating from the LFT are likely to be at greater risk of iatrogenic injury because they may reach very near to the tonsillar fossa. A better understanding of the variable origin and branching pattern of the LFT will avoid injury to the hypoglossal nerve which passes superficially and very close to its termination.…”

The common carotid artery bifurcates into two terminal branches—the external and internal carotid arteries. The head, neck, and face regions principally get their blood supply from the external carotid artery and its branches. Some previous articles have mentioned the abnormal pattern of the external carotid artery branching and its variable origin. In this article, a rare case has been documented, having the combination of anomalies of the high carotid termination and bilateral variable origin of the ventral branches of the external carotid artery encountered during routine dissection of the head and neck region of a 55-year-old male cadaver in the Department of Anatomy. In this instance, on the right side of the neck, we observed the presence of a thyrolinguofacial trunk which arose from the ventral surface of the external carotid artery, and on the left side, the linguofacial trunk emerged from the ventral surface of the external carotid artery while the superior thyroid artery branched off directly from the left common carotid artery. This apart, there was bilateral high termination of the common carotid artery. Although the exact embryogenesis of such common arterial trunks anomalies and high carotid termination is not clear, detailed and precise anatomical knowledge of such a combination of anomalies will provide further insight for better radiological evaluation and to avert iatrogenic vascular injuries during any surgical procedures of the head and face region.

“…Understanding the blood vessels in the neck is essential for many clinical specialties. For example, extraoral ligation of the LA is performed for uncontrolled bleeding, and the presence of TLFT may be a risk factor for treatment failure and complications [9]. Anatomic variations in neck vessels are also important in the surgical or chemotherapeutic treatment of tongue cancer.…”

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). MethodsA 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. ResultsThe 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. Additionally, we observed fusiform dilatation of the intracranial right vertebral artery, which might have caused these symptoms. ConclusionTFLT is an extremely rare variant that usually arises from the external carotid artery (ECA). Only one case of TFLT arising from CCA has been previously reported in the relevant English-language literature. The presence of a common trunk of the 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 signi cant 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.
