• Vena subclavia
• Vena braquiocefalica
• Vena cefalica
• Vena yugular interna
• Vena yugular externa
• Subclavian vein
• Brachiocephalic vein
• Cephalic vein
• Interior jugular vein
• External jugular vein

During anatomical dissection of a female Caucasian cadaver in our department, we observed an unusual termination of seven veins at the jugulo-subclavian junction. Normally, the jugulo-subclavian junction is formed by the union of the internal jugular vein and the subclavian vein, and gives rise to the brachionocephalic vein. In our case, except from these two, five additional veins, namely the cephalic vein, the transverse cervical vein, the external jugular vein, the anterior jugular vein, and the vertebral vein, were also joined at the level of the jugulo-subclavian junction, in order to form the brachionocephalic vein. Such a variation has not yet been reported in the literature.

Normalmente, la uni車n y迆gulo-subclavia consiste en la uni車n de la vena yugular interna y la vena subclavia, que forman la vena braquiocef芍lica. En nuestro caso, adem芍s de estas dos venas, se observaron cinco venas adicionales, la vena cef芍lica, la vena cervical transversa, la vena yugular externa, la vena yugular anterior y la vena vertebral, la que tambi谷n se uni車 en el nivel de la uni車n y迆gulo-subclavia, a fin de formar la vena braquiocef芍lica. Tal variaci車n no ha sido reportado en la literatura.
