エホバの証人12 例のStanford A 型急性大動脈解離の緊急手術

The Jehovah’s Witnesses （JW） is well known for declining blood transfusions. Especially, cardiovascular surgery on JW poses unique challenges. We herein report 12 JW emergent cases of Stanford type A acute aortic dissection which underwent graft replacement between 2003 and 2019. Graft replacement of ascending aorta was performed in all cases. Operative time and anesthetic time were 344±100 and 396±109 minutes respectively. The mean intraoperative hemoglobin nadir was 4.9±1.2 g/dl. The postoperative hemoglobin nadir was 6.3 ±2.4 g/dl. There were 2 deaths within 24 hours after surgery. We did not transfuse any packed red blood cells, fresh frozen plasma or platelets for JW patients of Stanford type A acute aortic dissection surgery.
