A Timeline From Index Procedure To Complex Reinterventions For Thoracoabdominal Aortic Dissection

Area of Science:

• Cardiovascular Surgery
• Thoracic Aortic Disease
• Aortic Dissection Management

Background:

• Optimal management of acute type A aortic dissection (ATAAD) is controversial, with varied surgical approaches.
• Hemiarch, partial, or total arch replacement are common strategies, each with potential drawbacks.
• Hybrid techniques offer evolving options for complex ATAAD cases.

Purpose of the Study:

• To present a complex case of ATAAD requiring multistage reconstruction.
• To illustrate the utility of hybrid open and endovascular techniques in managing challenging aortic pathologies.
• To underscore the importance of individualized treatment strategies for ATAAD.

Main Methods:

• A 67-year-old male patient diagnosed with ATAAD presented with chest pain and hypertension.
• Initial hemiarch replacement was performed.
• Subsequent interventions utilized a hybrid approach combining open and endovascular techniques for progressive dilation, innominate artery dissection, and subclavian steal syndrome.

Main Results:

• The patient required multiple interventions following initial hemiarch replacement.
• A hybrid approach successfully addressed complex residual and progressive aortic pathology.
• This case demonstrates the feasibility of multistage reconstruction for intricate ATAAD.

Conclusions:

• Acute type A aortic dissection presents significant management challenges across all phases.
• No definitive consensus exists for the ideal initial management of ATAAD.
• Individualized, tailored care incorporating advanced techniques like fenestrated endografts is crucial for effective long-term management.
