A totally implanted injection port system for blood sampling and chemotherapy administration

Area of Science:

• Oncology
• Medical Devices
• Vascular Access

Background:

• Cancer patients often require long-term chemotherapy, necessitating reliable vascular access.
• Lack of peripheral venous access sites is common in patients undergoing aggressive cancer treatment.
• Central venous catheters are essential for administering chemotherapy and drawing blood samples.

Purpose of the Study:

• To evaluate the efficacy and safety of a totally implanted central venous catheter system.
• To assess the system's performance in patients with cancer lacking peripheral venous access.
• To determine the device's suitability for repeated infusions and blood draws during chemotherapy.

Main Methods:

• A totally implanted system with a subcutaneous injection port and central venous catheter was used.
• The study included 35 cancer patients undergoing aggressive chemotherapy.
• System performance was tracked for cumulative duration, infusion success, blood sampling success, and complications.

Main Results:

• The system provided over 2,900 days of successful vascular access across all patients.
• Infusions and injections were consistently successful.
• Blood sampling was successful in 90% of attempts.
• No irreversible catheter occlusions, catheter shear, or system-related infections were reported.
• The system required minimal maintenance, only needing flushing with heparinized saline after each use.

Conclusions:

• The totally implanted central venous catheter system demonstrates high efficacy and safety for cancer patients.
• The device offers significant advantages in patient acceptance and reduced maintenance compared to other central venous catheters.
• This system provides a reliable solution for long-term vascular access in challenging patient populations.
