Cervical angina has been defined as chest pain that resembles true cardiac angina but originates from the disorders of the cervical spine. Thus, physicians and spine surgeons alike should raise awareness of this unusual condition for diagnosis and treatment. Particularly when neurologic signs and symptoms are present, there should be a strong suspicion for cervical angina in any patient with inadequately explained noncardiac chest pain. Cervical angina can be diagnosed according to negative cardiac workups, positive neurologic examination, and cervical radiographic findings (herniated disk, spinal cord compression, or foraminal encroachment). However, the mechanisms of pain production in cervical angina remain unclear. Previous studies attributed the pain to cervical nerve root compression, cervical sympathetic afferent fibers, referred pain, or lesions of the posterior horn of the spinal cord. Conservative treatments, which include neck collar fixation, head traction, and nonsteroidal anti-inflammatory drugs, have been determined to be successful in most patients with cervical angina. But when conservative treatment fails, anterior cervical surgery with complete decompression of the spinal cord and/or nerve root has been identified to effectively relieve cervical angina symptoms.
