Planning
Choice of modality
- X-ray of central venous catheters is enough after insertion, and in suspected movement.
- Fluoroscopy of central venous catheters is indicated when there is malfunction of the catheter.
Evaluation
Catheter tip position
For catheters positioned to low or high, estimate the difference between the current and optimal placement.
Regular catheters:
The distal tip of jugular catheters should lie in the lower part of the superior vena cava.[1] For left-sides catheters, a tip in the upper right atrium has also been suggested.[1] However, the cardiac silhouettes are regarded as not reliable for this purpose, compared to using the carina as a landmark.[1] Hence, a catheter tip between 55 and 30 mm below the level of the carina is regarded as acceptable placement on anteroposterior X-rays.[2]
Central dialysis catheters:
- The tip of nontunneled jugular hemodialysis catheters should be in the superior vena cava, and not in the right atrium.[3]
- The tip of high-flow tunneled hemodialysis catheters should be within the right upper atrium.[3]
Basic screening
Report
- Catheter position, and distance from optimal position if applicable.
- Even absence of lung opacities and pleural fluid.
