Management of acute limb ischemia is complex and time sensitive, and delays in diagnosis and treatment may lead to irreversible tissue damage. Current data challenge the commonly accepted 6-hour ischemic threshold for acute limb ischemia, although variations in practice remain. Patients with chronic peripheral artery disease may tolerate longer ischemia time due to presence of collateral circulation. Here the authors discuss the presentation, workup, management, and postoperative care of patients with acute limb ischemia, with a focus on how management is altered depending on the duration and degree of ischemia.
急性肢体缺血的治疗非常复杂且时间紧迫,如果诊断和治疗延误,可能会导致不可逆转的组织损伤。目前的数据对急性肢体缺血通常接受的 6 小时缺血时间限制提出了挑战,尽管实践中仍存在差异。由于存在侧支循环,慢性外周动脉疾病患者可能能够耐受更长的缺血时间。本文作者讨论了急性肢体缺血患者的临床表现、检查、治疗和术后护理,重点讨论了根据缺血持续时间和程度如何改变治疗方法。
