Cervical manipulation and cerebrovascular ischemia. A rare but dangerous association. Monocentric experience in a high CEA volume center and literature review.

Abstract Background: A correlation between stroke and cervical manipulation in the neck is reported in the literature with increasing frequency, and each new publication seems to rekindle the debate. The manipulations in the cervical region is potentially dangerous for arterial vessels. The aim of this work is to analyze the incidence of these events in the experience of a center with high volume surgery, in which emergency interventions are performed for acute cerebrovascular Ischemia. Methods: Data were collected regarding patients undergoing carotid endarterectomy surgery for neurological symptoms of cerebrovascular insufficiency over a seven-year period. Results: The intervention was conducted urgently in 66 cases for acute symptoms (7.6%) with a median symptom interval / CEA: 39.4 ± 5.4 h) in 32 cases for hemispheric transient ischemic attack, while in 34 for minor stroke. Only in 1 case (1.5%) did a condition of severe spondyloarthrosis of the cervical spine occur in acute carotid plaque in C4-C5. In another case (1.5%) a cervical trauma caused by beatings is documented. Conclusions: Manipulations of the neck and cervical spine can rarely cause or contribute to worsening neurological symptoms, however they should always be considered.
