Sex differences in the epidemiology of spontaneous and traumatic cervical artery dissections.

BACKGROUND

Recent studies show cervical artery dissection (CeAD) is equally common between sexes, and that the incidence of CeAD has risen at a greater rate in females than males. In this population-based study, we identify sex differences in patients diagnosed with spontaneous and traumatic CeAD.

METHODS

144 patients with spontaneous or traumatic CeAD were studied for sex differences in medical comorbidities, presenting symptoms and outcomes.

RESULTS

Females were more likely to carry a diagnosis of migraine, while males were more likely to have hyperlipidaemia. Females were more likely to present with neck pain, males with stroke. Females were significantly more likely to develop recurrent dissections in the study period.

CONCLUSIONS

These findings underscore the importance of understanding CeAD through the lens of sex differences and may explain the significant rise in the diagnosis of CeAD in females. These findings support the importance of considering sex-specific risk factors and medical comorbidities with sex predilection in the diagnosis and management of CeAD. Furthermore, it emphasises the importance of female patients understanding risk factors and presenting signs that should prompt evaluation for CeAD.
