摘要

Abnormal variation in the vascular system is a common feature more commonly observed in veins than arteries. Hence surgeons must have a thorough knowledge of both normal and aberrant architecture of the neck’s veins to avoid unintended harm to vascular structures. Usually, the external jugular vein (EJV) drains into the jugulo-subclavian confluence (60%), subclavian vein (36%), or directly into the internal jugular vein (IJV) (4%). The common facial vein (CFV) usually drains into the internal jugular vein, at the level of the hyoid bone. Here, we report a unique case in which common facial vein drains into IJV at much lower level and also external jugular vein (EJV) is noted to drain into internal jugular vein (IJV) forming a confluence of three veins at the level of cricoid cartilage in a squamous cell carcinoma patient undergoing neck dissection. There are not well documented similar surgical findings available in the literature. This was an important observation during routine neck dissection and suitable measures were taken to avoid any fatal complications. Further research with large cadaveric studies might assist us in identifying anatomical variations and establishing the knowledge of the neck’s topography.
