Summary
This study shows that replacing the entire aortic arch in acute aortic dissection cases is safe and effective. This surgical strategy offers good mid-term results for patients requiring complete resection of dissected aorta.
Area of Science:
- Cardiovascular Surgery
- Aortic Dissection Management
- Surgical Innovation
Background:
- Acute aortic dissection poses significant surgical challenges.
- Effective management requires precise resection of affected aortic segments.
- Evaluating novel surgical strategies is crucial for improving patient outcomes.
Purpose of the Study:
- To assess a surgical strategy for acute aortic dissection.
- To emphasize curative resection of dissected aortic segments.
- To evaluate the efficacy of ascending aorta replacement including the aortic arch.
Main Methods:
- A cohort of 29 patients with acute aortic dissection were analyzed.
- Group 1 (16 patients) underwent complete resection of dissected ascending aorta or ascending aorta with aortic arch.
- Group 2 (13 patients) had proximal aortic replacement for entire aortic dissection.
Main Results:
- Perioperative cerebrovascular events and early mortality were 10.3% and 3.4%, exclusively in Group 2.
- No significant long-term mortality or morbidity differences were observed between groups.
- Seven patients in Group 2 showed a persistent patent false lumen post-surgery.
Conclusions:
- Extending ascending aorta replacement to the complete aortic arch is feasible.
- This approach does not elevate operative risk for suitable patients.
- Total aortic arch replacement is indicated for complete aortic dissection resection, yielding good mid-term results.
