Insights
Recent minor neck trauma or strain is linked to cervical arterial dissection in younger adults. Migraine was a notable risk factor, unlike general cardiovascular issues. Early recognition of neurological symptoms is key.
Area of Science:
- Neurology
- Vascular Medicine
- Epidemiology
Background:
- Cervical arterial dissection (CAD) is a significant cause of stroke in young individuals.
- It may result from pre-existing arterial susceptibility combined with a precipitating event like minor trauma.
- Early identification of at-risk individuals or dissections can improve medical intervention.
Purpose of the Study:
- To identify risk factors for cervical arterial dissection.
- To describe the clinical presentation of individuals with CAD.
- To investigate the association between CAD and preceding events or therapies.
Main Methods:
- A cross-sectional case-control study was conducted.
- Participants were individuals aged 55 or younger with confirmed vertebral or internal carotid artery dissection.
- A comparison group with ischemic stroke but no dissection was age- and sex-matched.
Main Results:
- Seventeen of 24 CAD participants (71%) reported recent minor mechanical neck trauma or strain.
- Four participants reported recent neck manipulative therapy.
- Migraine was a common cardiovascular risk factor; other general risk factors were infrequent.
Conclusions:
- Recent minor mechanical trauma or strain to the head or neck is associated with CAD.
- Migraine appears to be a relevant risk factor, but general cardiovascular risk factors are less so in this cohort.
- Preceding transient neurological symptoms are common and may aid in early identification of CAD.
Study Design:
Cross-sectional case-control study.
Objectives:
To identify risk factors and clinical presentation of individuals with cervical arterial dissection.
Background:
Cervical arterial dissection is a common cause of stroke in young people and has in rare cases been associated with cervical manipulative therapy. The mechanism is considered to involve pre-existing arterial susceptibility and a precipitating event, such as minor trauma. Identification of individuals at risk or early recognition of a dissection in progress could help expedite medical intervention and avoid inappropriate treatment.
Methods:
Participants were individuals 55 years of age or younger from the Hunter region of New South Wales, Australia with radiologically confirmed vertebral or internal carotid artery dissection and an age- and sex-matched comparison group. Participants were interviewed about risk factors, preceding events, and clinical features of their stroke. Physical examination of joint mobility and soft tissue compliance was undertaken.
Results:
Twenty-four participants with cervical arterial dissection and 21 matched comparisons with ischemic stroke but not dissection were included in the study. Seventeen (71%) of the 24 participants with dissection reported a recent history of minor mechanical neck trauma or strain, with 4 of these 17 reporting recent neck manipulative therapy treatment. Cardiovascular risk factors were uncommon, with the exception of diagnosed migraine. Among the participants with dissection, 67% reported transient ischemic features in the month prior to their admission for dissection.
Conclusion:
Recent minor mechanical trauma or strain to the head or neck appears to be associated with cervical arterial dissection. General cardiovascular risk factors, with the exception of migraine, were not important risk factors for dissection in this cohort. Preceding transient neurological symptoms appear to occur commonly and may assist in the identification of this serious pathology.
Level Of Evidence:
Prognosis, level 4.
