Unusual complications during pulmonary artery catheterization

Area of Science:

• Cardiology
• Medical Devices
• Interventional Procedures

Background:

• Pulmonary artery catheterization is a common procedure for hemodynamic monitoring.
• The Seldinger technique is frequently used for percutaneous vascular access.
• Unusual complications during these procedures require careful consideration.

Purpose of the Study:

• To describe two uncommon complications encountered during pulmonary artery catheterization.
• To highlight potential risks associated with the Seldinger technique in this context.
• To discuss methods for preventing and managing these complications.

Main Methods:

• Case report of two patients experiencing complications during pulmonary artery catheterization.
• Utilized the Seldinger technique for percutaneous catheter insertion.
• Detailed description of the specific complications encountered.

Main Results:

• One case involved inadvertent entry into the right pleural space during internal jugular vein catheterization.
• The second case presented with separation of the introducer shaft from the hub, posing an embolization risk.
• Both complications occurred with percutaneous catheterization using the Seldinger technique.

Conclusions:

• Awareness of these rare complications is crucial for clinicians performing pulmonary artery catheterization.
• Proper technique and vigilance can help prevent inadvertent pleural entry.
• Strategies for managing introducer separation and preventing embolization are essential.
