Cerebral protection for aortic arch surgery: deep hypothermia

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• Aortic arch aneurysm repair has seen significant technical advancements over the past 20 years.
• Deep hypothermic circulatory arrest (DHCA) is widely adopted for managing aortic arch aneurysms.
• The branched graft technique has been utilized since the late 1990s, enhancing surgical results.

Purpose of the Study:

• To describe a refined technique for total aortic arch replacement.
• To highlight the benefits of deep hypothermia and selective cerebral perfusion in aortic arch surgery.

Main Methods:

• The study details a specific surgical technique for total arch replacement.
• This method involves the use of deep hypothermia.
• Selective cerebral perfusion is employed to protect brain function during the procedure.

Main Results:

• The described branched graft technique has improved surgical outcomes.
• The technique has considerably simplified the treatment of aortic arch aneurysms.
• The approach using deep hypothermia and selective cerebral perfusion is effective.

Conclusions:

• Total arch replacement using deep hypothermia and selective cerebral perfusion is a viable and effective technique.
• The branched graft approach offers improved outcomes and simplification in aortic arch aneurysm surgery.
• Continued evolution of surgical techniques benefits patients with aortic arch aneurysms.
