Summary
Fenestrated and branched endografts are revolutionizing thoracoabdominal aneurysm repair, expanding treatment options and improving outcomes. Advances in endovascular aortic repair (EVAR) technology and techniques are making these complex procedures more accessible.
Area of Science:
- Vascular Surgery
- Endovascular Repair
- Aortic Aneurysm Treatment
Background:
- Thoracoabdominal aneurysm repair is shifting towards less invasive methods.
- Evolution of branched and fenestrated grafts enables endograft use in the visceral aorta and aortic arch.
- These advancements broaden patient suitability for endovascular aortic repair (EVAR).
Purpose of the Study:
- To review the current status of fenestrated and branched endografting.
- To examine workarounds enhancing the application of endovascular aortic repair (EVAR).
Main Methods:
- Review of current literature on fenestrated and branched endografting.
- Analysis of technological advancements and procedural adaptations.
- Discussion of key factors for successful outcomes.
Main Results:
- Branched and fenestrated grafts have expanded EVAR to previously untreatable aortic segments.
- These techniques have led to reduced mortality and morbidity in specialized centers.
- Development of modular devices aims to increase technology dispersion.
Conclusions:
- Fenestrated and branched endografting represent a paradigm shift in thoracoabdominal aneurysm repair.
- Preoperative planning, advanced imaging, and surgical experience are crucial for successful EVAR outcomes.
- Ongoing innovation is expanding the reach and applicability of endovascular aortic repair.
