Reproduction of the original Fig 21 of Pensa,23 showing an example of a typical descending thoracic VA providing T1 partially and T2 entirely. The supreme intercostal artery (originating from an unlabeled costocervical trunk) is clearly distinguished from the thoracic VA, both in the illustration and in the Pensa's text, the latter emphasizing the respective precostal and retrocostal locations of the 2 vessels. However, the nomenclature remains uncertain; Pensa labeled the descending thoracic VA as an arteria intercostalis suprema (A.i.s). V indicates vertebral artery; T.t.c, thyrocervical trunk. P.
