Percutaneous vascular cannulation for extracorporeal life support (ECLS): a modified technique

Area of Science:

• Cardiovascular Surgery
• Medical Devices
• Interventional Cardiology

Background:

• Vascular access and cannulation are critical for extracorporeal circulation (ECC) and patient safety.
• Cannulation techniques have evolved from surgical cutdown to percutaneous methods.
• Standard percutaneous approaches require optimization for efficiency and safety.

Purpose of the Study:

• To describe a novel modified percutaneous cannulation technique.
• To report clinical experience and observed complications with this technique.
• To evaluate the safety and feasibility of the modified cannulation method.

Main Methods:

• A modified Seldinger technique using three guidewires and dilators.
• Pre-cannulation concentric pursestring sutures to minimize bleeding.
• Cannulation performed under direct fluoroscopic guidance.

Main Results:

• 38 patients (31 VV-ECLS, 7 VA-ECLS) underwent cannulation from 1997-2009.
• Total of 69 venous cannulations with an average cannula size of 23 Fr.
• Mean procedure time of 40 minutes, with only 3 adverse events.

Conclusions:

• The described modified percutaneous cannulation technique is safe and feasible.
• The technique is associated with a very low incidence of procedure-related complications.
• The method may require a longer procedural time compared to standard techniques.
