Simplified elephant trunk graft technique for aortic arch replacement.

Area of Science:

• Cardiovascular Surgery
• Vascular Graft Technology
• Aortic Pathology

Background:

• Aortic replacement operations require secure distal anastomosis.
• Fragile aortic walls in aneurysms and dissections pose surgical challenges.
• Ensuring patency and preventing complications in aortic repair is critical.

Purpose of the Study:

• To present a refined elephant trunk graft design.
• To enhance the facilitation and reinforcement of the distal anastomosis.
• To demonstrate the applicability of the modified graft in complex aortic surgeries.

Main Methods:

• A novel four-branch graft was developed with an integrated cuff.
• The cuff is utilized for the distal anastomosis.
• The graft's trunk is inserted into the distal aortic stump.

Main Results:

• The refined graft design facilitates a more robust distal anastomosis.
• The technique is shown to be feasible for extensive aortic aneurysms with fragile walls.
• The method is applicable to acute aortic dissection cases requiring false lumen thromboocclusion.

Conclusions:

• The refined elephant trunk graft offers improved distal anastomosis in aortic surgery.
• This technique provides a viable solution for challenging aortic pathologies.
• The graft design aids in managing extensive aneurysms and acute aortic dissections.
