Are All Cutdown Procedures Central Line Placements?
No, cutdown procedures are not exclusively central line placements—cutdowns can be performed for both peripheral and central venous access, though they are increasingly discouraged for central access due to higher infection and thrombosis risks compared to percutaneous techniques.
Understanding Cutdown Procedures
Cutdown procedures involve surgical exposure of a vein to establish vascular access, and they can target either peripheral or central veins:
Peripheral Venous Cutdowns
- Peripheral cutdowns typically access the saphenous vein at the ankle or the cephalic vein in the arm, providing peripheral (not central) venous access 1.
- These procedures were historically a mainstay in trauma care but have progressively lost favor since the introduction of percutaneous techniques 1.
- The catheter tip in peripheral cutdowns remains in peripheral veins and does not reach the central venous system 1.
Central Venous Cutdowns
- Cephalic vein cutdowns can be used to place central venous catheters when the catheter is advanced centrally to the superior vena cava or right atrium 2.
- In one prospective series, cephalic vein cutdown successfully placed central catheters in 82% of 100 cancer patients, with the catheter tip positioned centrally 2.
- Open surgical cutdown remains a common technique in pediatric surgery but often leads to central vein occlusion near the entry site 3.
Current Guideline Recommendations Against Cutdowns for Central Access
Multiple high-quality guidelines explicitly recommend against using cutdown techniques for central venous catheter placement:
The CDC guidelines (2002) state: "Do not routinely use arterial or venous cutdown procedures as a method to insert catheters" (Category IA—the strongest recommendation level) 3.
The ESPEN guidelines (2009) recommend that "placement by surgical cutdown is not recommended, in terms of cost-effectiveness and risk of infection" (Grade A) 3.
The American College of Surgeons recommends avoiding surgical cutdown as it is not cost-effective and increases infection risk (Grade A) 4.
Why Cutdowns Are Discouraged for Central Access
The evidence demonstrates several disadvantages:
- Higher infection rates: Cutdowns carry increased risk of wound and catheter infection compared to percutaneous placement 5.
- Increased thrombosis risk: Open surgical cutdown often leads to central vein occlusion near the entry site 3.
- Not cost-effective: The procedure requires more time, resources, and carries higher complication rates 3.
- Ultrasound-guided percutaneous techniques are superior: Real-time ultrasound guidance for percutaneous central venous access increases success rates from 87.6% to 97.6% and reduces complications from 13.5% to 4.0% 4.
When Cutdowns May Still Be Considered
Despite guideline recommendations against routine use, cutdowns retain limited clinical utility:
- Emergency situations where percutaneous access is impossible or results in unacceptable time delays 1.
- Patients with no percutaneous options due to vessel thrombosis, anatomical abnormalities, or failed multiple percutaneous attempts 5.
- Some oncology practices continue using cephalic vein cutdown for long-term central access devices, with one series showing 82% success rate and acceptable complication profiles 2.
Common Pitfalls to Avoid
- Do not assume all cutdowns are central lines: Peripheral cutdowns (saphenous, basilic) provide only peripheral access unless the catheter is advanced centrally 1.
- Do not use cutdown as a first-line approach for central venous access when ultrasound-guided percutaneous techniques are available 3, 4.
- Recognize that cutdown-placed central lines have higher thrombosis rates: This is particularly important in pediatric patients where central vein preservation is critical 3.
