Port Placement via the Anterior Jugular Venous System: Case Report, Anatomic Considerations, and Literature Review

Figure 4

Schematic drawing illustrating the segmental anatomy of a typically and fully developed anterior jugular venous system (AJVS) consisting of three segments (three arrows) with the jugular venous arch (JVA) as the transverse midline segment (large arrow). AJV: anterior jugular vein; EJV: external jugular vein; IJV: internal jugular vein; SV: subclavian vein; SVC: superior vena cava.
