Summary
A novel AV cannula facilitates antegrade selective cerebral perfusion (ASCP) during aortic arch surgery. This technique allows earlier insertion and maintains access to supra-aortic vessels (SAV) for improved surgical efficiency.
Area of Science:
- Cardiovascular Surgery
- Medical Devices
- Neurosurgery
Background:
- Antegrade selective cerebral perfusion (ASCP) is crucial for brain protection in aortic arch surgery.
- Current ASCP methods involve cannula insertion after aortic arch opening and hypothermic circulatory arrest.
- This can complicate access to supra-aortic vessels (SAV).
Purpose of the Study:
- To introduce a new surgical technique and cannula for ASCP.
- To describe the AV (Andrea Venturini) cannula and its application.
- To highlight advantages over existing ASCP methods.
Main Methods:
- A novel AV cannula designed for Seldinger's technique guidewire insertion into SAV.
- Cannula can also be inserted from SAV ostia.
- Allows insertion before hypothermic circulatory arrest and aortic arch opening.
Main Results:
- The AV cannula enables direct insertion into SAV using a guidewire.
- Cannula can be placed prior to initiating circulatory arrest.
- Supra-aortic vessel ostia remain accessible during the procedure.
Conclusions:
- The AV cannula offers a new approach to ASCP in aortic arch surgery.
- This technique potentially improves surgical access and efficiency.
- Facilitates easier and faster anastomosis or reimplantation of SAV.
