Locoregional Anesthesia Has Lower Risks of Cardiac Complications Than General Anesthesia After Prolonged Endovascular Repair of Abdominal Aortic Aneurysms
Authors' conclusion
Locoregional anesthesia can be a safe and effective alternative to general anesthesia, particularly in EVAR cases with anticipated complexity and prolonged operative times, as it offers the potential benefit of reduced cardiac complications.
Study context
- Population
- Adults undergoing prolonged (>157 minutes) nonemergent, intact, infrarenal endovascular aneurysm repair (EVAR); ACS NSQIP targeted database 2012–2022prolonged EVAR
- Participants
- 4,075 adults
- Exposure
- Locoregional vs general anesthesia for prolonged EVAR
- Locoregional anesthesian = 324
- General anesthesian = 955reference
- Outcome
- MI and 30-day mortality
- Follow-up
- 30 days
Methodological details1:3 propensity-score matched, large-scale national registry

Main finding
As reported in the abstract
MI and 30-day mortality
30-day mortality
P = 0.35
- Locoregional vs General: P = 0.04 — MI: lower risk with locoregional
Observational data: associations, not effects.
Further findings

- Specific concomitant procedures, aneurysm anatomy and comorbidities associated with prolonged EVAR
