The important role of the AJVS as a collateral also becomes apparent in the context presented by Yamada et al.
We describe a case of placement of a port catheter by direct puncture of the horizontal lateral segment of the AJVS and crossover through the JVA that was technically possible without the use of special equipment, not necessitating greater effort or significantly higher costs than an ordinary port implantation, and feasible despite a tortuous and relatively narrow diameter JVA.
In the unusual constellation of patients with central venous occlusion on one side and requiring ipsilateral port implantation, closer consideration of a potentially fully developed and enlarged AJVS is warranted, as this vessel has been proven clinically to be a major cervical crossover collateral vein.
For clinicians, the AJVS can play an important role as a collateral for the insertion of port catheters, pacemaker leads, or other types of central devices.

Caption: 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).
The JVA is an infrequently found transverse connecting trunk extending across the midline between the two anterior jugular veins (AJV) of either side and lying in the suprasternal space between superficial and pretracheal layers of the cervical fascia.
During its formative years, AJVS had trouble finding an Alaskan bank willing to lend it money and when it did, the service was poor.
