RAJANIGANDHA, V et al. An Anomalous Left External Jugular Vein Draining into Right Subclavian Vein: A Case Report. Int. J. Morphol. [online]. 2008, vol.26, n.4, pp. 893-895. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022008000400018.
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 for interventional radiologists too who perform transjugular procedures, such as port implantations and the transjugular intrahepatic portosystemic shunt or selective venous samplings. Results of recent studies report that the superficial veins, especially the external jugular vein (EJV), is been increasingly utilized for cannulation to conduct diagnostic and therapeutic procedures. We report a very unusual presentation of external jugular vein on left side of an embalmed male cadáver. Embryological evaluations of the anomaly was done and compared with available literature which showed that the observed variation is rare.
