A novel technique for hybrid aortic arch reconstruction: the deployment cuff technique

Area of Science:

• Cardiovascular Surgery
• Thoracic Aortic Disease
• Endovascular Repair

Background:

• Extensive thoracic aortic aneurysmal disease involving the arch and descending aorta presents significant surgical challenges.
• The frozen elephant trunk (FET) procedure, combining open arch repair with stented thoracic endograft deployment, shows promise but faces technical difficulties in precise device placement.
• In aortic dissection, proximal false lumen backflow requires obliteration to prevent complications.

Purpose of the Study:

• To describe a novel technique for precise frozen elephant trunk endograft deployment.
• To ensure accurate positioning and obliteration of the proximal false lumen in patients with aortic dissection.

Main Methods:

• A modified technique for the frozen elephant trunk procedure is presented.
• The method focuses on achieving exact deployment of the endovascular stent graft.
• Specific steps are detailed to obliterate back bleeding through the false lumen proximally.

Main Results:

• The described technique facilitates precise stent graft deployment in the thoracic aorta.
• It effectively addresses the issue of proximal false lumen backflow in aortic dissection.
• This approach aims to improve outcomes for complex aortic arch and descending aorta repairs.

Conclusions:

• The described technique offers a solution for precise frozen elephant trunk endograft deployment.
• It enables effective obliteration of false lumen flow, crucial for managing aortic dissection.
• This method may enhance the safety and efficacy of single-stage FET procedures for extensive thoracic aortic disease.
