Infrainguinal bypass under triple nerve block in patients with severely compromised left ventricular ejection fraction and chronic limb-threatening ischemia.

ABSTRACT Severely compromised left ventricular ejection fraction (LVEF) is a major limitation for lower extremity bypass reconstruction both under general (GA) or neuraxial (NA) anesthesia. A series of 8 infrainguinal bypass procedures were performed under peripheral nerve block (PNB) in 5 patients (3 males and 2 females, median age 67 years) with chronic limb-threatening ischemia (CLTI) and preoperative LVEF ≤35% (median 27%; range 20-35%). There were no conversions to NA/GA or early postoperative complications.
