Abstract

The sites of origin of the branches of the subclavian artery depict numerous anatomical variations. However, a common trunk of the internal thoracic artery (ITA) and thycocervical trunk (TCT) arising from the vertebral artery is a rare anatomical finding. Herein, we present the first case in which the common trunk of the left ITA and TCT arose from the ipsilateral proximal vertebral artery as discovered on pre-therapeutic evaluation by multidetector-row computed tomography and clearly confirmed by selective angiography. It is important to recognize such anatomic variations for surgical, diagnostic, and interventional radiologic procedures in the head, neck, thorax, and abdomen.
