Cervical laminaplasty caused sympathetic nerve injury leading to myocardial stunning, characterized by inverted T waves, temporary wall motion abnormalities, and reduced myocardial MIBG uptake.
Case Report (n=1)
This case highlights that surgical injury to sympathetic nerves during cervical vertebrae operations can cause myocardial stunning, mimicking acute coronary syndromes.
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 the same area where the wall motion abnormalities appeared in the echocardiogram, although no abnormalities were detected with myocardial thallium scintigraphy and coronary angiography. The myocardial stunning was caused by injury to the sympathetic nerves from a surgical procedure on the cervical vertebrae.
Hatakeyama et al. (Fri,) conducted a case report in Myocardial stunning (n=1). Cervical laminaplasty (sympathetic nerve injury) was evaluated on Development of myocardial stunning (ECG changes, wall motion abnormality, MIBG uptake reduction). Cervical laminaplasty caused sympathetic nerve injury leading to myocardial stunning, characterized by inverted T waves, temporary wall motion abnormalities, and reduced myocardial MIBG uptake.
