"Why is frozen elephant trunk better than classical elephant trunk?"

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• Complex aortic arch disease presents a significant surgical challenge, often involving the ascending aorta and descending thoracic aorta.
• Surgical and endovascular techniques have evolved to simplify the management of these complex conditions.

Purpose of the Study:

• To review and analyze the advantages and drawbacks of the conventional elephant trunk technique and the frozen elephant trunk technique.
• To compare these two approaches for treating complex aortic arch disease from clinical and practical perspectives.

Main Methods:

• Review of existing literature on surgical and endovascular techniques for aortic arch disease.
• Analysis of the conventional elephant trunk technique, first proposed in 1983.
• Analysis of the frozen elephant trunk technique, a modern evolution involving stent graft deployment.

Main Results:

• The conventional elephant trunk technique is a foundational procedure for aortic arch disease.
• The frozen elephant trunk technique offers advancements in managing the proximal descending thoracic aorta.
• Both techniques have distinct clinical and practical considerations that require careful evaluation.

Conclusions:

• The choice between conventional and frozen elephant trunk techniques depends on specific patient factors and disease complexity.
• Further analysis is needed to fully elucidate the long-term outcomes and comparative efficacy of these evolving techniques.
• Understanding the nuances of each approach is crucial for optimizing treatment strategies in complex aortic arch disease.
