Abstract

The authors report a rare variation of the anterior jugular and internal jugular veins in a 78-year-old male donor. An enlarged and curved left anterior jugular vein (AJV) was formed as the continuation of the left common facial vein (CFV). The left AJV's diameter was wider than the internal jugular vein (IJV) and measured around 5 mm greater than the IJV's diameter and a channel connected the two veins. The right AJV and CFV continued from the two divisions of the right facial vein. The right AJV's diameter was smaller than the right IJV's diameter. The right external jugular vein was absent. No concurrent pathology supported the abnormal dimension of the left AJV and the findings were indicative of a variant anatomy. These variations have rarely been reported and have important clinical correlations. Failed IJV cannulation may result if the variant neck veins are missed. However, variant veins may serve as collateral channels and patch material in IJV reconstruction, carotid angioplasty, and ventricular-jugular shunts.

颈静脉的独特变异及其临床意义。
作者报告了一名 78 岁男性供体颈前静脉和颈内静脉的罕见变异。左侧颈前静脉(AJV)增大弯曲,是左侧面部总静脉(CFV)的延续。左颈静脉的直径比颈内静脉(IJV)宽,比 IJV 的直径大 5 毫米左右,两条静脉之间有一条通道相连。右侧 AJV 和 CFV 从右侧面部静脉的两个分支延续下来。右 AJV 的直径小于右 IJV 的直径。右侧颈外静脉缺失。没有并发病理支持左侧 AJV 的异常尺寸,这些发现表明解剖结构存在变异。这些变异很少见报道,但与临床有重要关联。如果错过了变异的颈部静脉,可能会导致 IJV 插管失败。不过,变异静脉可作为侧支通道和补片材料,用于颈内静脉重建、颈动脉血管成形术和心室-颈静脉分流术。

期刊介绍: "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
