Abstract:

Knowledge of the varying drainage patterns of superficial veins of head and neck is not only important for anatomists but also for surgeons operating at this level and to clinicians in general. The variations are also important for interventional radiologists who perform transjugular procedures such as port implantations and intrahepatic portosystemic shunts or selective venous samplings in patients with hyperparathyroidism of unknown origin. Results of recent studies report that the superficial veins especially the external jugular vein have been increasingly used for cannulation to conduct diagnostic and therapeutic procedures. Although studies have been done on variations of veins of head and neck, external jugular vein duplication along the whole length has not been reported so far. We report a very unusual bilateral presentation of external jugular vein duplication along its whole length in an embalmed male cadaver observed during routine dissection. Embryological evaluation of the anomaly was done and compared with the available literature which showed that the observed variation was rare.
