Post-Dissection Single-Stage Arch and Descending Aorta Replacement via Clamshell Incision

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Aneurysm Research

Background:

• Residual dissections following aortic Type A repair are a frequent complication.
• These residual defects can progress to aortic aneurysm formation, necessitating further intervention.
• Surgical repair of complex aortic arch pathologies presents significant challenges and risks.

Purpose of the Study:

• To describe a modified single-stage "arch-first" surgical technique for managing residual dissections after Type A aortic repair.
• To highlight the utility of a trifurcated graft in this specific surgical approach.
• To present an alternative surgical strategy for high-risk patients with aortic arch involvement.

Main Methods:

• The study details a variation of the clamshell incision approach.
• Emphasis is placed on the "arch-first" strategy, prioritizing aortic arch repair.
• A specific technique utilizing a trifurcated graft for reconstruction is presented.

Main Results:

• The "arch-first" approach with a trifurcated graft provides a viable option for specific patient cohorts.
• This technique addresses complex residual dissections and arch involvement.
• The described method offers a potentially less complex surgical pathway in select cases.

Conclusions:

• A single-stage "arch-first" repair using a trifurcated graft is an effective strategy for select patients with residual dissections after Type A repair.
• This approach can mitigate the risks associated with complex aortic arch surgery.
• Further studies may elucidate the long-term outcomes of this specific surgical variation.
