Image intensification - A solution for difficult guidewire insertion for central venous access: A case report.

Area of Science:

• Cardiovascular Surgery
• Medical Imaging
• Interventional Cardiology

Background:

• Central venous catheter (CVC) insertion is crucial for cardiac surgery.
• Difficulties in CVC placement can lead to complications.
• Ultrasound guidance has limitations in visualizing guidewire obstructions.

Observation:

• A patient undergoing cardiac surgery experienced guidewire resistance during internal jugular vein cannulation.
• Ultrasound provided limited visualization of the guidewire path and obstruction.
• Continuous image intensification (fluoroscopy) was applied to overcome the obstruction.

Findings:

• Fluoroscopy precisely identified the anatomical location and cause of guidewire obstruction.
• Real-time visualization enabled safe guidewire manipulation and successful catheter insertion.
• This approach minimized further attempts and potential complications.

Implications:

• Image intensification can reduce CVC malposition and mechanical complications.
• Fluoroscopy offers a valuable alternative for challenging CVC placements.
• Further comparative studies of ultrasound-guided vs. fluoroscopy-guided CVC insertion are warranted.
