Myocardial stunning caused by sympathetic nerve injury after an operation on cervical vertebrae

In this case, electrocardiographic inverted T waves appeared after cervical laminaplasty and echocardiogram showed temporary wall motion abnormality. Myocardial metaiodobenzylguanidine (MIBG) uptake was obviously reduced in t he same area where the wall motion abnormalities appeared in the echocardio gram, although no abnormalities were detected with myocardial thallium scin tigraphy and coronary angiography. The myocardial stunning was caused by in jury to the sympathetic nerves from a surgical procedure on the cervical ve rtebrae.
