摘　　要：BACKGROUND Left cardiac myxoma(CM)is the most common benign tumor of primary cardiac tumors,but because of its special position caused by pathological physiology change,caused by the complications of the heavier,the surface is often accompanied by blood clots,once fall out,it causes peripheral vascular embolization,such as acute lower limb artery embo-lization,harmfulness is large,high morbidity,and easy to occur repeatedly.CASE SUMMARY A 67-year-old male patient suddenly appeared numbness and weakness of the left lower limb and could not walk without obvious incentive.The patient was finally diagnosed as left CM complicated with acute lower limb arterial embolism after completing cardiac ultrasound,computer tomography angiography,and histopathological analysis,such as hematoxylin-eosin stain staining,immunohistochemistry and special staining including alcian blue staining and periodic acid schiff staining.Arterial thrombosis was removed successfully by femoral artery thrombectomy,postoperative numbness and weakness of the patient’s left lower limb disappeared,skin temperature became warm,and dorsal foot artery pulsation was accessible.The patient was readmitted to the hospital 8 mo after discharge for left atrial mass resection,and was diagnosed as CM by postoperative histopathological examination.CONCLUSION Although CM is rare,it may be considered as the source of embolism in patients with acute limb ischemia.Repeated loss of thrombus on the tumor and its surface may lead to repeated embolism of peripheral vessels.Cardiac ultrasound is helpful for early diagnosis.Here,we use this case report to highlight left CM as an important cause of acute limb ischemia and to report our experience in the diagnosis and treatment of lower limb arterial embolism caused by CM detachment.
