Summary
This study presents a complex Zone 0 Hybrid Arch Repair using a delayed Frozen Elephant Trunk technique. This innovative approach minimizes operative risks by avoiding circulatory arrest and maintaining organ perfusion.
Area of Science:
- Cardiovascular Surgery
- Vascular Endovascular Therapy
Background:
- Aortic arch disease presents significant surgical challenges.
- Endovascular techniques are increasingly used for complex aortic arch pathologies.
Purpose of the Study:
- To describe a novel hybrid arch repair strategy for complex Zone 0 aortic arch disease.
- To evaluate the feasibility and safety of a delayed Frozen Elephant Trunk technique.
Main Methods:
- A Zone 0 Hybrid Arch Repair was performed using a delayed Frozen Elephant Trunk.
- Continuous cerebral and visceral organ perfusion was maintained.
- Mild hypothermia was employed, avoiding circulatory arrest.
Main Results:
- The described hybrid technique successfully addressed a complex Zone 0 aortic arch repair.
- Continuous perfusion and mild hypothermia were maintained throughout the procedure.
- The strategy aimed to reduce operative risks associated with traditional methods.
Conclusions:
- A delayed Frozen Elephant Trunk with continuous perfusion and mild hypothermia is a viable strategy for complex Zone 0 aortic arch repair.
- This approach offers a potential method to decrease operative risks.
- Integration of endovascular technologies in aortic arch surgery is expanding treatment options.
