Branched thoracic endovascular aortic repair (b-TEVAR) offers a feasible and safe treatment for aortic arch diseases, demonstrating acceptable mortality and stroke rates in early outcomes. This endovascular approach provides a viable alternative to open repair for select patient groups.
Area of Science:
- Cardiovascular Surgery
- Endovascular Interventions
- Aortic Disease Management
Background:
- Open repair is the standard for aortic arch diseases, but endovascular options are emerging.
- Branched stent grafts are specifically designed for complex aortic arch anatomy.
- b-TEVAR presents a new treatment avenue for specific patient subgroups.
Purpose of the Study:
- To investigate the early outcomes of branched thoracic endovascular aortic repair (b-TEVAR).
- To evaluate the safety and efficacy of b-TEVAR in various aortic arch diseases.
- To assess complications and reintervention rates associated with b-TEVAR.
Main Methods:
- Retrospective analysis of prospectively collected data from a single center.
- Inclusion of consecutive patients treated with custom-made inner branched arch endografts.
- Evaluation of technical success, 30-day mortality, stroke incidence, and late complications.
Main Results:
- High technical success rate (98%) in 54 patients with diverse aortic arch pathologies.
- Low 30-day mortality (5.5%) and major stroke incidence (5.5%).
- Acceptable rates of spinal cord ischemia and few early reinterventions required.
Conclusions:
- Branched thoracic endovascular aortic repair (b-TEVAR) is a feasible and safe treatment modality.
- b-TEVAR demonstrates acceptable mortality and stroke rates for aortic arch diseases.
- This endovascular approach offers a promising alternative for selected patients.
