Key result
Among 40 patients, endovascular AAA repair under spinal anesthesia resulted in lower stress response, superior hemodynamic stability, and better maintained renal function than conventional repair.
Why the study?
Does endovascular aneurysm repair under spinal anesthesia reduce hormonal stress response and improve hemodynamic stability compared to conventional aneurysm repair under general anesthesia in patients undergoing elective infrarenal AAA repair?

May support spinal anesthesia for EVAR to limit stress and preserve renal function; hypothesis-generating in small cohort, needs RCT confirmation.

Does endovascular aneurysm repair under spinal anesthesia reduce hormonal stress response and improve hemodynamic stability compared to conventional aneurysm repair under general anesthesia in patients undergoing elective infrarenal AAA repair?
EVAR under spinal anesthesia is associated with a lower hormonal stress response, superior hemodynamic stability, and better maintained renal function compared to conventional open repair under general anesthesia.
Kataja et al. (2007) conducted a cohort in elective infrarenal abdominal aortic aneurysm (AAA) (n=40). Endovascular aneurysm repair (EVAR) under spinal anesthesia vs. Conventional aneurysm repair (CAR) using general anesthesia with epidural blockade was evaluated on intraoperative and postoperative hormonal stress response, hemodynamic stability, fluid loading and renal function. Among 40 patients, endovascular AAA repair under spinal anesthesia resulted in lower stress response, superior hemodynamic stability, and better maintained renal function than conventional repair.
