Knowledge of the varying drainage patterns of superficial veins of head & neck, in particular, jugular veins are not only important for anatomists but also for the surgeons operating at this level and to clinicians in general. The variations are important also for interventional radiologists, who perform trans-jugular procedures, such as port implantations and trans-jugular intra-hepatic porto-systemic shunts or selective venous samplings. Results of recent studies report that the superficial veins, especially the external jugular vein, have been increasingly utilized for cannulation to conduct diagnostic and therapeutic procedures. We report a very unusual left-sided presentation of external jugular vein in an embalmed male cadaver. Embryological evaluations of the anomaly was done & compared with available literature, which showed that the observed variation is rare (Fig. 1, Ref. 12).
了解头颈部浅表静脉，尤其是颈静脉的不同引流模式，不仅对外科解剖学家很重要，对于在此水平进行手术的外科医生以及一般临床医生也很重要。这些变异对于进行经颈静脉操作（如端口植入、经颈静脉肝内门体分流术或选择性静脉采样）的介入放射科医生也很重要。最近的研究结果表明，浅表静脉，尤其是颈外静脉，越来越多地被用于插管以进行诊断和治疗程序。我们报告了一具经过防腐处理的男性尸体中颈外静脉非常不寻常的左侧表现。对该异常进行了胚胎学评估，并与现有文献进行了比较，结果表明观察到的变异很罕见（图1，参考文献12）。
