[Present-day policy of surgical treatment for type A acute aortic dissection]

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• Type A acute aortic dissection requires surgical intervention for patient recovery and to prevent fatal complications.
• The traditional supracoronary ascending aorta and proximal aortic arch replacement, while simpler, can lead to persistent false lumen complications.
• Advancements in surgical techniques and intensive care now allow for more extensive resections to improve long-term results.

Purpose of the Study:

• To evaluate the efficacy of the frozen elephant trunk technique in managing type A acute aortic dissection.
• To present the perioperative management strategy for type A acute aortic dissection at the authors' institution.
• To discuss the role and indications of the frozen elephant trunk technique in current clinical practice.

Main Methods:

• Review of surgical interventions for type A acute aortic dissection.
• Description of the 'frozen elephant trunk' technique for total aortic arch replacement.
• Analysis of perioperative therapeutic policies and outcomes.

Main Results:

• The frozen elephant trunk technique facilitates rapid thrombosis of the false lumen.
• This technique helps prevent disease progression in the thoracic aorta and promotes positive aortic remodeling.
• More extensive resections are feasible and beneficial for improving remote results in type A acute aortic dissection.

Conclusions:

• The frozen elephant trunk technique is a valuable advancement in treating type A acute aortic dissection.
• It offers advantages over traditional methods by addressing the persistent false lumen and improving aortic remodeling.
• The authors advocate for the integration of this technique into the management of type A acute aortic dissection.
