Is Left Innominate Vein Ligation during Aortic Arch Surgery Always Safe? A Case Report

Abstract

Ligation of the left innominate vein (LIV) expands the surgeon’s surgical field for ascending aorta and aortic arch procedures. Although it is considered a safe technique by most surgeons in that it is associated with only minor drawbacks, conflicting views exist regarding this method. We herein describe a 70-year-old woman who underwent ascending aorta replacement due to an aneurysm with subsequent cerebral dysfunction caused by extended brain edema, possibly related to LIV ligation, leading to her death.
