What type of catheter is used for cannulation in thoracoabdominal surgery?

In thoracoabdominal surgery, a balloon tip catheter is often utilized for cannulation, particularly in contexts where the management of blood flow and pressure is critical. These catheters feature a flexible tip that can be inflated, which allows the clinician to navigate the catheter into the desired vascular location. The balloon tip provides stability within the vessel, reduces the risk of dislodgment, and enhances the ability to manage the circulation during the surgical procedure.

This type of catheter is especially useful in surgeries that involve significant manipulation of the thoracic and abdominal vessels, as it allows for better precision in placement compared to other catheter types. Additionally, balloon tip catheters can facilitate the measurement of pressures within various chambers of the heart or vessels, giving extra information that can be vital during complex surgeries.

The other catheter types mentioned are less suited for the specific challenges presented in thoracoabdominal surgery due to their design limitations or intended uses, such as standard IV catheters, which are typically intended for peripheral access and not suitable for deep vascular access required in thoracoabdominal procedures.
