Abstract:
Objective To discuss the accuracy and effectiveness of digital subtraction angiography(DSA)in determining the cause of limb ischemia after extra corporeal membrane oxygenation(ECMO.Methods The clinical data of 3 child patients,who developed 4 times of acute limb ischemia during perioperative period of ECMO at the Affiliated Children's Hospital of Zhengzhou University of China from July to October of 2023,were retrospectively analyzed.In all the child patients,emergency angiography was carried out to quickly identify the cause,then,appropriate treatment plan was adopted to open the blood vessels of the right lower limb.Results After the child patients entered the operating room and received DSA examination,the causes of the limb ischemia were quickly identified.After treatment,the blood supply to the lower limbs was restored.Except for one child who experienced irreversible necrosis of the distal limb due to repeated ischemia-reperfusion injury and required amputation,the other two child patients recovered well.Conclusion It is of great significance to perform DSA examination as soon as possible when the child patients develop limb ischemic manifestations after ECMO so as to quickly identify the cause,promptly restore blood supply to ischemic limbs and increase limb preservation rate,besides,DSA examination can also be used as a preventive measure for child patients after ECMO.
