Develops after an episode of seizure or end arterectomy
Up until 2009, almost all patients were treated with a posterior laminectomy, associated with arterectomy
and even partial pedicle resection when needed.
Amongst them 9 cases (50%) were post thyroidectomy, 1 (5.6%) patient underwent neck dissection, 1 (5.6%) patient had carotid end arterectomy
and 7 cases (38.9%) were reported after thoracic surgeries including pneumonectomy2, mediastinal biopsy1, cardiac surgery2, esophagectomy2.
As biomarker, S100A8/A9 correlates with the extent of subclinical carotid and coronary artery disease, increases rapidly in plasma during myocardial ischemia and necrosis, and is associated with unfavorable prognosis in MI and heart failure patients and in patients undergoing carotid arterectomy

Cervical plexus block has also been effectively used in other surgeries like carotid end arterectomy
, lymph node biopsy (or) excision.
