    Postoperative electrocardiograms revealed T-wave inversions after cervical laminectomy. These changes were suspected to be of neurogenic origin, as cardiac evaluations were normal.

    Area of Science:

    • Cardiology
    • Neurosurgery
    • Electrocardiography

    Background:

    • Cervical laminectomy is a surgical procedure to remove a portion of the lamina in the cervical spine.
    • Electrocardiogram (ECG) abnormalities can occur postoperatively, necessitating careful evaluation.
    • Distinguishing cardiac from non-cardiac causes of ECG changes is crucial for patient management.

    Observation:

    • A 64-year-old woman exhibited significant T-wave inversions on her postoperative ECG following an extensive cervical laminectomy.
    • Cardiac enzyme and isoenzyme studies were largely negative, with only a trace of CK-MB in one sample.
    • The patient's clinical presentation did not suggest myocardial ischemia.

    Findings:

    • Coronary angiography, including an ergonovine study, performed six months post-surgery, revealed normal coronary arteries.

  • The absence of typical ischemic indicators and normal angiography findings support a non-cardiac etiology.
  • The neurogenic origin of the T-wave changes is suspected due to the context of the cervical spine surgery.

    • Implications:

    • This case highlights the importance of considering neurogenic causes for ECG abnormalities after spinal surgery.
    • Neurogenic T-wave changes can mimic cardiac ischemia, underscoring the need for comprehensive diagnostic workups.
    • Further research into the mechanisms and clinical significance of neurogenic T-wave changes is warranted.
