Descending endograft for DeBakey type 1 aortic dissection: pro.

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Disease Management

Background:

• DeBakey type 1 acute aortic dissection (DBT1-AAD) poses significant surgical challenges.
• Persistent patent false lumen in DBT1-AAD is associated with poor prognosis and increased risk of aneurysm formation.
• Current surgical strategies for DBT1-AAD often require reintervention due to incomplete false lumen thrombosis.

Purpose of the Study:

• To review the rationale and evidence supporting the use of frozen elephant trunk (FET) technology in managing DBT1-AAD.
• To evaluate the potential benefits of FET in improving long-term outcomes for acute aortic dissection patients.
• To discuss the controversies and current evidence regarding FET surgery in the context of acute aortic dissection.

Main Methods:

• This perspective article synthesizes existing literature and clinical experience.
• It focuses on the application of total arch replacement (TAR) combined with antegrade stenting (FET) for DBT1-AAD.
• The review examines the technical aspects, outcomes, and risks associated with FET procedures.

Main Results:

• The FET technique aims to achieve complete false lumen thrombosis and reduce reoperation rates.
• While technically demanding, FET offers a potential solution to persistent false lumen patency.
• Evidence suggests FET may improve long-term aortic remodeling and reduce late complications.

Conclusions:

• Frozen elephant trunk (FET) surgery represents an aggressive approach to DBT1-AAD management.
• FET has the potential to improve long-term outcomes by promoting false lumen thrombosis and reducing reoperation rates.
• Further evidence is needed to fully establish the safety and efficacy of FET in acute aortic dissection, despite its promising advantages.
