[A new method for reversed bevel technique using single-branched graft in hemi-arch replacement]

Area of Science:

• Cardiovascular Surgery
• Vascular Surgery
• Surgical Techniques

Context:

• Hemi-arch replacement procedures can present challenges with graft anastomosis, particularly when proximal aortic access is limited.
• Performing proximal anastomosis under antegrade systemic perfusion requires precise and efficient surgical techniques.

Purpose:

• To introduce and describe a reversed bevel technique for single-branched grafts in hemi-arch replacement.
• To demonstrate how this technique facilitates both distal and proximal anastomosis, even with limited space.

Summary:

• The reversed bevel technique involves clamping the graft distally, positioning the side branch at the beveled site.
• This approach allows for a long elliptical distal anastomosis and an easier proximal anastomosis.
• The technique ensures an adequate surgical field for proximal aortic anastomosis.

Impact:

• This method enhances the ease and safety of hemi-arch replacement surgery.
• It provides a reliable solution for challenging proximal anastomosis scenarios.
• The technique contributes to improved surgical efficiency and potentially better patient outcomes in aortic arch surgery.
