The subcutaneous injection port: a new chest-wall artifact
Radiology
|January 1, 1985
Summary
Totally implanted central venous catheters with injection ports are used for long-term venous access. These devices can create artifacts on chest radiographs that may be mistaken for pulmonary lesions.
Area of Science:
- Radiology
- Medical Devices
Background:
- Central venous catheters are essential for long-term venous access in various medical conditions.
- Totally implanted systems with subcutaneous injection ports offer a discreet and convenient option for repeated venous access.
Purpose of the Study:
- To describe a novel artifact on chest radiographs caused by totally implanted central venous catheters with subcutaneous injection ports.
- To raise awareness among radiologists and clinicians about this potential imaging misinterpretation.
Main Methods:
- Review of chest radiographs from patients with totally implanted central venous catheters and subcutaneous injection ports.
- Identification and characterization of the specific imaging appearance of the artifact.
Main Results:
- A distinct artifact, related to the subcutaneous injection port, was identified on chest radiographs.
- This artifact can simulate the appearance of a pulmonary nodule or mass, potentially leading to misdiagnosis.
Conclusions:
- The subcutaneous injection port of totally implanted central venous catheters can produce a recognizable artifact on chest radiographs.
- Radiologists should be aware of this artifact to avoid misinterpreting it as a true pulmonary lesion, ensuring accurate patient diagnosis and management.
