Very rare malposition of central venous catheter in cardiac surgery patients

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Placement

Background:

• Central venous catheterisation is a common procedure with a significant risk of catheter malposition.
• Malposition can lead to severe complications including hemorrhage and venous thrombosis.
• Standard monitoring does not guarantee correct catheter placement.

Purpose of the Study:

• To report a rare series of four cases of central venous catheter malposition into the left internal mammary vein (LIMV).
• To highlight the increased risk of complications due to the thin and fragile nature of the LIMV.
• To emphasize strategies for minimizing catheter malposition during central venous catheterisation.

Main Methods:

• Retrospective review of four cases of catheter malposition into the LIMV over a three-year period.
• Analysis of potential contributing factors and associated complications.
• Review of literature on central venous catheterisation techniques and malposition risks.

Main Results:

• Four cases of catheter malposition into the LIMV were identified.
• The LIMV's thin and fragile wall increases complication probability.
• Right jugular vein access is associated with the lowest malposition incidence.

Conclusions:

• Central venous catheter malposition, particularly into the LIMV, presents a significant risk.
• Ultrasonography guidance and immediate post-procedure imaging are crucial for minimizing malposition.
• Careful technique and appropriate imaging can reduce the incidence and severity of complications.
