Abstract

Objective: The present study describes a rare anatomical variation of the anterior jugular vein (AJV) and discusses its clinical relevance.

Methods: A head and neck specimen fixed in 10% formaldehyde from a 42-year-old female cadaver was submitted to angio technique with pre-vulcanized latex and water-soluble ink. During a routine dissection for the discipline of topographic anatomy, the presence of an arcuate AJV was detected in the anterior triangle of the neck.

Results: An arcuate AJV was formed by the confluence of the submental and facial veins in the left submandibular region, which presented a complex network of anastomoses superficially to the left submandibular gland. After its origin, this vessel curved to the right at the level of the laryngeal prominence and followed the medial border of the right sternohyoid muscle to flow into the right AJV. In this topography, the arcuate AJV was located between the sternocleidomastoid muscle's anterior margin and the thyroid gland's right lobe. The presence of anastomoses between the two AJVs communicating the submandibular triangles was not detected.

Conclusion: The arcuate AJV is a relevant anatomical variant in the superficial venous drainage of the neck that should be known by head and neck surgeons and radiologists to avoid surgical iatrogenic events.

颈前弧形静脉：一例罕见病例报告及其临床意义。

目的：本研究描述了颈前静脉（AJV）的一种罕见解剖变异，并讨论了其临床意义：本研究描述了颈前静脉（AJV）的一种罕见解剖变异，并讨论了其临床意义：方法：将一具 42 岁女性尸体的头颈部标本用 10% 甲醛固定，并使用预硫化乳胶和水溶性墨水进行血管技术处理。在进行地形解剖的常规解剖过程中，发现颈部前三角区存在弧形 AJV：弧形 AJV 由左侧下颌下区域的下颌下静脉和面部静脉汇合而成，在左侧下颌下腺的浅表呈现出复杂的吻合网。这条血管在起源后，在喉突水平向右弯曲，沿着右胸骨舌骨肌内侧边界流入右 AJV。在这种地形图中，弧形 AJV 位于胸锁乳突肌前缘和甲状腺右叶之间。未发现沟通颌下三角区的两条 AJV 之间存在吻合：结论：弧形 AJV 是颈部浅静脉引流的一个相关解剖变异，头颈部外科医生和放射科医生应了解这一变异，以避免手术中的先天性事件。

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.
