Superficial veins of the head and neck are utilised for central venous cannulation, oral reconstruction and parenteral nutrition in debilitated patients. Clinical and sonological examinations of these veins may provide clues toward underlying cardiac pathology. Hence, although variations in these vessels are common, a sound knowledge of such variations becomes clinically important to surgeons, radiologists and interventional anaesthetists. We report a rare case of a left-sided double external jugular vein where the common facial vein continued as the second external jugular vein, and where there was a communicating channel between the internal jugular vein on the same side and the anterior jugular vein.
头颈部浅静脉可用于衰弱患者的中心静脉插管、口腔重建和肠外营养。这些静脉的临床和超声检查可能为潜在的心脏病理学提供线索。因此，尽管这些血管的变异很常见，但对于外科医生、放射科医生和介入麻醉师来说，了解这些变异的基本知识变得非常重要。我们报告了一例罕见的左侧双颈外静脉病例，其中面总静脉继续作为第二颈外静脉，同侧颈内静脉与前颈静脉之间存在交通通道。
