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

Figure 1

CT with administration of contrast media through a left peripheral vein. (a) Coronal maximum intensity projection image shows chronic occlusion of the left-sided central veins with cervical collateral veins from the left to the right side and here reaching the nonoccluded right-sided central veins; slight metal artifacts by the right-sided pacemaker. (b) Coronal multiplanar reconstruction image showing a partially quite tortuous u-shape horizontal-transverse midline vein in the jugulum (dotted ellipse), the AJVS with the JVA.
