Central venous catheters (CVCs) can remain in place from days to years, but duration depends on catheter type, patient needs, and complication risks.

Typical Lifespans by Catheter Type and Setting

Catheter Type / Setting	Average Duration	Key Details & Risks	Citations
Short-term, non-tunneled CVCs	7–14 days	Infection risk rises after 9–14 days; guidelines advise removal when no longer needed, not by fixed time (Regev, 2024; Mısırlıoğlu et al., 2023; Knapek et al., 2024)
Tunneled or cuffed CVCs (e.g., for chemotherapy, parenteral nutrition)	Several months to years	Mean lifespans reported: 122 days (≈4 months) (Nightingale et al., 1997); median 123–391 days (with repairs) (Santhana et al., 2021); can last >1 year with proper care (Bond et al., 2023; Wouters et al., 2019; Moukarzel et al., 1994)
Peripherally inserted central catheters (PICCs)	Weeks to months	Shorter lifespan than implanted ports; higher complication rates (Sun & Wu, 2022)
Implanted port catheters	Several years	Longest lifespan, lowest infection risk (Sun & Wu, 2022)

Factors Influencing Catheter Longevity

• Infection risk increases with time: Especially after 9–14 days for short-term CVCs (Regev, 2024; Mısırlıoğlu et al., 2023; Pitiriga et al., 2022).
• Complications: Thrombosis, mechanical failure, and infection are leading causes for removal (Nightingale et al., 1997; Mısırlıoğlu et al., 2023; Adwaney et al., 2019).
• Catheter repairs: Successful repairs can double catheter survival without increasing short-term infection risk (Bond et al., 2023; Wouters et al., 2019; Santhana et al., 2021).
• Patient age and site: Older patients and subclavian placements may have longer catheter life (Bass et al., 2011; Yu et al., 2019; Gish et al., 2016).
• Clinical guidelines: Recommend removal when no longer needed, not by a set duration (Regev, 2024; Mısırlıoğlu et al., 2023).

Special Populations

• Pediatric and home parenteral nutrition patients: CVCs can last months to years, with some lasting over a decade if complications are managed (Moukarzel et al., 1994; Wouters et al., 2019; Santhana et al., 2021).
• Hemodialysis patients: Tunneled catheters may last 2–3 years, but risk of central venous stenosis increases with duration and number of catheters (Adwaney et al., 2019; Yu et al., 2019).

Conclusion

CVC longevity varies widely: short-term catheters are typically used for up to 2 weeks, while tunneled or implanted devices can last months to years if complications are avoided. Regular assessment and prompt removal when no longer needed are essential to minimize risks.
