Insights
Mild neck trauma, including manual therapy, significantly increases the risk of craniocervical arterial dissection in young adults. Cardiovascular risk factors were less common in dissection patients compared to stroke controls.
Area of Science:
- Neurology
- Vascular Medicine
- Public Health
Background:
- Craniocervical arterial dissection is a leading cause of ischemic stroke in young individuals.
- Association with neck manipulation suggests potential triggers.
- Identifying risk factors and early signs is crucial for timely intervention and risk management.
Purpose of the Study:
- To identify risk factors for craniocervical arterial dissection.
- To determine the presenting features of craniocervical arterial dissection.
- To compare risk factors and preceding events in dissection patients versus stroke controls.
Main Methods:
- Retrospective case-control study comparing patients with craniocervical arterial dissection (vertebral or internal carotid artery) to stroke controls.
- Inclusion criteria: Patients aged ≤ 55 years from New South Wales, Australia, with radiographically confirmed or suspected dissection.
- Medical records were reviewed for clinical features, symptoms, and preceding events, particularly mild mechanical trauma to the head and neck.
Main Results:
- Mild mechanical trauma to the head and neck, including manual therapy, within three weeks preceding the event was reported by 64% of dissection patients versus 7% of controls (Odds Ratio 23.53).
- Cardiovascular risk factors for stroke were significantly less prevalent in the dissection group compared to the control group.
- The study included 47 dissection patients (mean age 37.6 years) and 43 controls (mean age 42.6 years).
Conclusions:
- Mild mechanical trauma to the cervical spine is a significant risk factor for craniocervical arterial dissection in younger individuals.
- Craniocervical arterial dissection patients present with fewer traditional cardiovascular risk factors than other stroke patients.
- Early recognition of potential trauma-related dissection is vital for prompt medical intervention.
Abstract:
Craniocervical arterial dissection is one of the most common causes of ischaemic stroke in young people and is occasionally associated with neck manipulation. Identification of individuals at risk will guide risk management. Early recognition of dissection in progress will expedite medical intervention. Study aims were to identify risk factors and presenting features of craniocervical arterial dissection. Medical records of patients from the Hunter region of New South Wales, Australia aged ≤ 55 years with radiographically confirmed or suspected vertebral or internal carotid artery dissection, were retrospectively compared with matched controls with stroke from some other cause. Records were inspected for details of clinical features, presenting signs and symptoms and preceding events. Records of 47 dissection patients (27 males, mean age 37.6 years) and 43 controls (22 males, mean age 42.6 years) were inspected. Thirty (64%) dissection patients but only three (7%) controls reported an episode of mild mechanical trauma, including manual therapy, to the cervical spine within the preceding three weeks. Mild mechanical trauma to the head and neck was significantly associated with craniocervical arterial dissection (OR 23.53). Cardiovascular risk factors for stroke were less evident in the dissection group (<1 factor per case) compared to the controls (>3).
