Combined epidural anesthesia & general anesthesia for aorto-renal bypass: two case reports.

Aorto-renal bypass surgery is associated with significant hemodynamic alterations as well as other comorbidities due to necessity of aortic cross-clamping and release during vascular anastomosis. Combined epidural and general anesthesia for the aorto-renal bypass surgeries provides not only hemodynamic stability during aortic cross-clamping but is also associated with increased graft blood flow, graft survival and decreased morbidity and mortality in intraoperative and postoperative period. Two cases of aorto-renal bypass are presented, for which combined epidural and general anesthesia techniques were applied.
