摘要静脉-动脉体外膜肺氧合（VA-ECMO）是重度循环衰竭患者重要的救治技术，其应用也越来越广泛。经股动脉置管简单便捷，成为成人VA-ECMO最常用的置管方式。下肢缺血是经股动脉VA-ECMO治疗过程中的常见并发症，一旦发生将严重影响患者预后及生存质量。为了规范VA-ECMO治疗期间下肢缺血的管理，降低致残率及病死率，中国医师协会体外生命支持专业委员会和山东省医师协会体外生命支持专业委员会特组织国内具有ECMO熟练使用经验的多学科医学专家，基于文献回顾和临床实践经验制定了《中国成人经股动脉VA-ECMO治疗期间下肢缺血防治专家共识（2023）》，以期为经股动脉VA-ECMO治疗期间下肢缺血的预防、监测及治疗提供有价值的参考。

abstractsVeno-arterial extracorporeal membrane oxygenation (VA-ECMO) is an important technique for the treatment of patients with severe circulatory failure, and is used in a wider range. Canulation through the femoral artery is simple and convenient, which has become the most commonly used canulation method of VA-ECMO for adults. Lower limb ischemia is a common complication in transfemoral VA-ECMO therapy, which will seriously affect the prognosis and quality of life of patients. In order to standardize the lower limb ischemia management during VA-ECMO treatment and reduce disability and mortality, Extracorporeal Life Support Professional Committee of Chinese Medical Doctor Association and Extracorporeal Life Support Professional Committee of Shandong Physician Association organized multidisciplinary medical experts with ECMO proficiency from China to develop the Expert consensus on prevention and treatment of lower limb ischemia during transfemoral veno-arterial extracorporeal membrane oxygenation therapy in adults in China (2023), based on literature review and their clinical practice experience. This consensus is expected to provide valuable reference for the prevention, monitoring and treatment of lower limb ischemia during femoral artery VA-ECMO treatment.
