Endovascular aneurysm repair under local anesthesia through bilateral percutaneous femoral access is a safe strategy to improve early outcomes and reduce hospital stay.
BACKGROUND: To estimate the impact of anesthetic conduct, alone and in combination with the type of femoral access, on early results after endovascular aneurysm repair (EVAR).
METHODS: A retrospective multicenter analysis on patients undergoing elective standard EVAR at four academic centers was performed. Patients undergoing the procedure through either local or general anesthesia were compared. Comparative subanalyses of the two groups were performed for the type of femoral access to evaluate further impact on outcomes.
RESULTS: Five hundred twenty-four patients underwent elective standard EVAR, of which 207 (39.5%) under general anesthesia and 317 (60.5%) under local anesthesia. Patients who underwent general anesthesia had higher 30-day mortality rates (3.4% vs. 0.3%, P=0.005), as well as slightly worse 30-day major systemic complication rates (8.2% vs. 5.4%, P=0.195). There were no differences in terms of reinterventions (2.1% vs. 2.5%, P=0.768) and aneurysm-related mortality (0% vs. 0.4%, P=0.422) at one year. Total intervention times were significantly longer in the general anesthesia group (126 vs. 89 minutes, P=0.001), as well as the total length of hospital stay (7.6 vs. 5.3 days, P=0.007). At subanalyses, the combination of local anesthesia with bilateral percutaneous femoral access further improved 30-day outcomes and determined an additional reduction in total intervention times and ICU stays.
CONCLUSIONS: EVAR performed under local anesthesia has a significantly better impact on early results when compared to general anesthesia. Combining percutaneous bilateral femoral access to local anesthesia reduced procedural times, ICU stays and consequently improved early results.
