Summary

Port-a-Cath systems showed a low complication rate, with one event per 2000 patient days. Infections were only observed in peritoneal catheters, suggesting benefits of standardized techniques and supervision.

Area of Science:

  • Medical Devices
  • Surgical Oncology
  • Infection Control

Background:

  • Implantable central venous access devices are crucial for long-term therapies.
  • Standardization of devices and surgical techniques may impact complication rates.
  • Port-a-Cath systems are commonly used for venous, arterial, and epidural access.

Purpose of the Study:

  • To evaluate the complication rate of Port-a-Cath systems over a five-year period.
  • To identify specific catheter types associated with higher complication risks.
  • To assess the impact of a uniform implantation technique and postoperative care on safety.

Main Methods:

  • Retrospective analysis of 205 patients receiving Port-a-Cath implants between 1983 and 1988.
  • Data collection included implant type (venous, peritoneal, arterial, epidural, pleural), duration, and complications.

  • Analysis focused on overall complication frequency and specific infection rates.

    • Main Results:

    • A total of 88,345 patient days (242 patient years) were analyzed.
    • An average complication rate of one event per 2000 patient days was observed.
    • Catheter-system infections were exclusively documented in peritoneal catheters.

    Conclusions:

    • The use of a single Port-a-Cath system and a uniform implantation technique by a limited surgical team contributed to a low complication rate.
    • Strict postoperative supervision by oncology nurses appears to be a key factor in maintaining device safety.
    • Peritoneal catheters represent a higher risk for catheter-system infections compared to other implant types.
