Abstract

Purpose: Various anatomical variations in the branching pattern of the external carotid arteries are known to occur with significant frequency and have been documented in published literature. The purpose of this case report is to document and discuss variations in the branching patterns of the external carotid artery as seen in an anatomical donor and determine the clinical relevance of these variations.

Case presentation: A routine dissection of an 89-year-old female anatomical donor, whose cause of death was reported as acute myocardial infarction and atherosclerotic heart disease, revealed variations in the branching patterns of both external carotid arteries. Bilaterally, the common carotid arteries bifurcated at the C4 vertebral level. On the left side, an occipitoauricular trunk originated 0.5 mm superior to the common carotid artery's bifurcation, whereas, on the right side, an occipitoauriculopharyngeal trunk branching 0.8 mm superior to the bifurcation of the common carotid artery was observed before branching into an occipitoauricular trunk and ascending pharyngeal artery.

Conclusion: This case report reinforces previous publications on arterial branching patterns and the importance of imaging prior to procedures. Clinically, these variations may impact surgical approaches, endovascular procedures within the neck, and vascular pathology management.

双侧颈外动脉分支变化：1例报告。

目的：颈外动脉分支模式的各种解剖变异已知发生频率显著，并已在已发表的文献中记录。本病例报告的目的是记录和讨论在解剖供体中看到的颈外动脉分支模式的变化，并确定这些变化的临床相关性。病例介绍：对一名89岁女性解剖供体进行常规解剖，其死因报告为急性心肌梗死和动脉粥样硬化性心脏病，发现颈外动脉分支模式的变化。双侧颈总动脉在C4椎体水平分叉。在左侧，枕耳干起源于颈总动脉分支上方0.5 mm处，而在右侧，枕耳咽干分支于颈总动脉分支上方0.8 mm处，然后分支为枕耳干和咽升动脉。结论：本病例报告强化了先前关于动脉分支模式的出版物和手术前影像学的重要性。在临床上，这些变异可能影响手术入路、颈部血管内手术和血管病理处理。

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.
