Femorally inserted central catheters with exit site at mid-thigh
Abstract:
Background: Femorally inserted central catheters are increasingly used, especially after the COVID-19 pandemic, also thanks to widespread of tunneling techniques that allow the exit site to be moved away from the groin.
Methods: In this retrospective observational study, femorally inserted catheters, with exit site at mid-thigh and the tip in Inferior vena cava or in Inferior vena cava at the junction with right atrium, have been observed and complications have been analyzed. All catheters were inserted by trained Nurses of a tertiary hospital Vascular Access Team.
Results: In 142 catheters (126 inserted via common femoral vein and 16 inserted via superficial femoral vein) and 3060 catheter days, we observed an infection rate of 1.3 events/1000 catheter days (all of them in oncologic patients and up to 30 days of catheterization), 2 cases of thrombotic events (1.41%) and 17 cases of accidental removal (11.97%). Other rare complications, as primary malposition, tip migration, arterial pseudoaneurysm, have been recorded. The average length of catheters inserted, from the exit site to the tip, was 47.6 ± 2.4 cm.
Conclusion: The attention to the correct position of the tip, the exit site at mid-thigh and the new techniques during insertion make these femoral catheters as safe as other central vascular access devices. For this kind of central access device, a catheter at least 50 cm long is needed.
