主动脉手术主要包括胸腹主动脉、主动脉弓以及主要侧肢的血管手术。急诊手术比例大,需要进行必要的检查后即行手术,手术中由于阻断大血管并用人工血管置换病变血管过程中会造成重要脏器不同程度的缺血性损害,如果术中对重要脏器缺血性损害的保护不到位或效果不好,术后会引起不同程度的并发症,影响病人术后是否顺利恢复[1]。重要脏器缺血性损伤的治疗和功能恢复等是围术期管理的重点。1临床资料回顾2014年1月至2015年3月间我科完成的22例大血管手 Aortic surgery mainly includes the thoracoabdominal aorta, aortic arch, and major lateral limb vascular surgery. A large proportion of emergency surgery, the need for the necessary examination after the line surgery, surgery as a result of blocking the large blood vessels and vascular replacement with artificial blood vessels will cause varying degrees of important organ ischemic damage, if the surgery on the lack of important organs Bloody damage protection is not in place or the effect is not good, postoperative will cause varying degrees of complications, affecting the patient after the successful recovery [1]. Important organ ischemic injury treatment and functional recovery is the focus of perioperative management. 1 clinical data reviewed in our department from January 2014 to March 2015 completed 22 cases of vascular hand
