Abstract

Objectives: To report our experience and compare the results of percutaneous endovascular aortic aneurysm repair (PEVAR) performed under monitored anesthesia care (MAC) to PEVAR under general anesthesia (GA). Methods: A retrospective review of patients who underwent non-emergency endovascular abdominal aortic aneurysm repair (EVAR) was completed. Patients were excluded if they had a complex repair, including fenestrated, branched, or parallel endografting. Demographics, operative data, 30-day mortality/morbidity and postoperative outcomes were analyzed. Results: A total of 159 patients were identified with a median age of 69. 115 patients had PEVAR, 45 (39.1%) PEVAR MAC and 70 (60.9%) PEVAR GA. PEVAR MAC compared to PEVAR GA had decreased operative time (106 vs. 134 min, P < 0.001), time in the operating room (163 vs. 245 min, P = 0.016), and estimated blood loss (EBL) (115 vs. 176 mL P = 0.012). There was no statistically significant difference in the hospital length of stay (LOS) (1.9 vs. 2.7 days, P = 0.133), and post-operative complications including pulmonary (2.2 vs. 2.9%, P = 0.835). Forty-four patients had EVAR with a femoral cutdown (FC), including 14 PEVAR conversions. PEVAR conversion was associated with higher EBL (543 vs. 323 mL, P = 0.03), operative time (230 vs. 178 min, P = 0.01), and operating room time (307 vs. 275 min, P = 0.01) compared to planned EVAR with FC. Conclusions: PEVAR under MAC is associated with shorter time in the operating room compared to PEVAR under GA. PEVAR under MAC does however not decrease overall morbidities, including postoperative pulmonary complications.
