Current practice utilizes the estimated length of the catheter from puncture site to the junction of superior vena cava / right atrium (SVC-RA) for guiding tip placement. Next the catheter tip placement was confirmed by radiographic imaging prior to use of the line for administration of chemotherapy medications. In this case, the catheter is often mal-positioned and requires adjustment and repeat radiographic imaging in order to ensure proper placement, ideally at the SVC-RA junction. These potentially additional procedures are time-consuming and also expose patients, nurses and physicians to radiations.
