Inadvertent transpericardial insertion of a central venous line with cardiac tamponade failure of preventive...

Area of Science:

• Cardiology
• Anesthesiology
• Intensive Care Medicine

Background:

• Central venous catheter (CVC) placement is a common procedure in perioperative and intensive care settings.
• Complications associated with CVCs can range from thrombosis to life-threatening events like cardiac tamponade.
• Ensuring correct catheter tip placement is paramount for patient safety.

Observation:

• A 56-year-old male, post-cardiac surgery, developed cardiac tamponade after contrast medium administration via a CVC.
• Pericardiotomy revealed the CVC traversing the pericardial sac before re-entering the superior vena cava.
• The catheter position was not detected by standard safety checks like chest radiography, free venous blood return, or manometry.

Findings:

• Standard preventive practices for CVC placement may not always detect malposition, particularly in unusual anatomical presentations.
• The case highlights a rare but potentially fatal complication of CVC malposition.
• An unusual high reflection was noted near the catheter's path through the pericardial sac.

Implications:

• Anesthesiologists and intensivists must be aware of the limitations of routine safety measures for CVC placement.
• Continuous vigilance and recognition of potential pitfalls are essential to prevent severe adverse events.
• This case underscores the need for a high index of suspicion for malposition in patients developing unexpected complications.
