Local Versus General Anesthesia in Emergency Endovascular Repair of Infrarenal Abdominal Aortic Aneurysm

The choice of anesthesia in emergency endovascular aneurysm repair (EVAR) remains unexplored. This study performed a retrospective analysis to compare the 30-day outcomes of patients who underwent emergency infrarenal EVAR receiving local anesthesia (LA) or general anesthesia (GA). After propensity-score matching/multivariable analysis to balance preoperative differences, patients under LA were found to have lower 30-day mortality, pulmonary, renal, and wound complications, 30-day readmission, shorter operative time, and shorter hospital stay. In emergency EVAR, it may be advisable to consider LA over GA for eligible patients. Prospective studies in the future can be warranted to further support this anesthesia practice.
