Novel Technique Using Polyester Fabric and Fibrin Sealant Patch for Acute Aortic Dissection

Area of Science:

• Cardiovascular Surgery
• Biomaterials Science
• Vascular Biology

Background:

• Acute aortic dissection poses significant surgical challenges.
• Effective reinforcement and hemostasis of the aortic stump are critical for successful repair.
• Current techniques may have limitations regarding circulatory arrest time and embolism risk.

Purpose of the Study:

• To present a simple and effective technique for acute aortic dissection repair.
• To describe the preparation and application of a composite patch for aortic stump reinforcement and hemostasis.
• To highlight the advantages of this novel technique in minimizing complications.

Main Methods:

• A composite patch was created by combining a polyester fabric sheet with a fibrin sealant patch (FSP).
• The polyester fabric was cut and adhered to the FSP using fibrin glue, forming a reinforced patch.
• The composite patch was trimmed and inserted into the false lumen to reinforce the aortic stump.

Main Results:

• The composite patch provides effective reinforcement and hemostasis of the aortic stump.
• Preparation during systemic cooling minimizes circulatory arrest time.
• Direct exposure of the false lumen to fibrin glue is avoided, significantly lowering embolism risk.
• The FSP lining enhances hemostasis for suture holes.

Conclusions:

• This technique offers a safe and effective method for managing acute aortic dissection.
• The combined polyester fabric and FSP patch presents advantages in reducing surgical time and embolic complications.
• This approach enhances hemostatic control at the aortic stump, improving surgical outcomes.
