Endovascular grafts for thoracic aortic pathologies.

Area of Science:

• Cardiovascular Surgery
• Vascular Surgery
• Interventional Cardiology

Background:

• Endovascular aortic repair (EVAR) is increasingly used for descending thoracic aorta aneurysms.
• This technique demands specialized equipment and skills not typical for cardiothoracic surgeons.
• EVAR is currently indicated for high-risk surgical candidates.

Purpose of the Study:

• To evaluate the efficacy and safety of EVAR for descending thoracic aorta aneurysms.
• To compare EVAR outcomes with traditional surgical approaches.
• To discuss the evolving techniques in EVAR for complex aortic pathologies.

Main Methods:

• Retrospective analysis of patients undergoing EVAR for descending thoracic aorta aneurysms.
• Comparison of perioperative and early mortality rates with historical surgical data.
• Review of advanced EVAR techniques for aortic arch and thoraco-abdominal aneurysms.

Main Results:

• EVAR provides a less invasive alternative to open surgery, avoiding cardiopulmonary bypass and large incisions.
• Procedures can often be performed under local anesthesia.
• Early mortality in high-risk patients treated with EVAR at the author's institution is comparable to published surgical results.

Conclusions:

• EVAR is a viable and effective treatment for descending thoracic aorta aneurysms, particularly in high-risk patients.
• Ongoing technical advancements are expanding EVAR's applicability to more complex aortic diseases.
• EVAR demonstrates promising early outcomes, comparable to traditional surgical methods for selected patients.
