Management of an unusual complication during placement of a pulmonary artery catheter

Area of Science:

• Cardiology
• Medical Devices
• Interventional Procedures

Background:

• Pulmonary artery catheters are crucial for hemodynamic monitoring.
• Percutaneous introducer sheaths facilitate catheter placement.
• Complications during insertion can impede patient care.

Observation:

• A malfunctioning pulmonary artery catheter was removed via a right internal jugular vein introducer sheath.
• A second pulmonary artery catheter became lodged, resistant to advancement or withdrawal.
• Chest radiograph revealed a bent introducer sheath and a looped pulmonary artery catheter.

Findings:

• The introducer sheath and pulmonary artery catheter were successfully withdrawn as a single unit under fluoroscopy.
• Withdrawal allowed the introducer sheath to straighten, releasing the catheter loop.
• Complete extraction was facilitated by managing the angulated sheath and looped catheter.

Implications:

• Complications can arise even with well-positioned introducer sheaths during pulmonary artery catheter placement.
• Continuous fluoroscopy is essential for managing such procedural difficulties.
• This technique ensures safe extraction, minimizing patient risk.
