Summary
Peripheral venous access ports offer a safe and effective alternative for long-term central venous access, comparable to traditional chest ports. These peripherally placed devices demonstrate favorable outcomes in patients requiring chemotherapy, hyperalimentation, and other long-term therapies.
Area of Science:
- Vascular Access Procedures
- Interventional Radiology
- Medical Device Outcomes
Background:
- Central venous catheters are crucial for long-term therapies.
- Peripheral venous access ports offer an alternative to traditional central venous access devices.
- Evaluating the safety and efficacy of peripherally placed ports is essential.
Purpose of the Study:
- To conduct a retrospective analysis of outcomes for central venous catheters with peripherally placed access ports.
- To compare the performance and complication rates of these peripheral ports with published data on central venous access devices.
Main Methods:
- 112 peripherally placed central venous access ports were inserted under sonographic guidance over 4 years.
- Ports were used for chemotherapy, hyperalimentation, long-term antibiotics, and blood sampling.
- Complication rates and catheter performance were assessed and compared to existing literature.
Main Results:
- All procedures successfully accessed upper arm veins, with ports functional for a median of 28,936 patient-days.
- Infectious complications occurred in 9.9% of ports, with site infections in 4.7% (Betadine) vs. 4.2% (standard prep), not statistically significant.
- Aspiration occlusion occurred in 11.7% of cases, with urokinase successfully restoring function in most instances. Complication rates were comparable to or better than chest ports.
Conclusions:
- Peripherally placed ports for long-term central venous access are a safe and effective option.
- Interventional radiologists can successfully place these devices in an interventional radiology suite.
- Outcomes are comparable to traditional chest ports, offering a viable alternative for patient care.
