Background and Objectives: Cervical artery dissection (CeAD) is a leading cause of ischemic stroke in younger adults, yet sex-specific variations in its clinical presentation, imaging characteristics, and outcomes remain underexplored. We aimed to evaluate these differences using data from a large, multicenter registry. Methods: We analyzed data from the STOP-CAD registry, which includes patients with radiologically confirmed non-traumatic CeAD enrolled between 2015 and 2021 across multiple centers. Clinical and imaging characteristics were compared between men and women using multivariable logistic regression. Outcomes assessed included ischemic stroke recurrence at 180 days, excellent functional outcome (modified Rankin Scale [mRS] 0–1) at 90 days, symptomatic intracerebral hemorrhage (sICH), and mortality. Results: Among 4,023 patients with CeAD, 1,783 (44.6%) were women. Compared to men, women were younger (median age: 42 vs 50 years), more likely to have a history of migraine (26.9% vs 8.3%) and connective tissue disorders (14.3% vs 5.8%), and presented more frequently with non-ischemic symptoms such as headache, neck pain, or tinnitus (adjusted OR [aOR] 2.0; 95% CI, 1.8–2.3; p<0.001). Women had significantly higher odds of vertebral artery dissection (OR, 1.3; 95% CI, 1.2-1.5; p<0.001), multivessel involvement (OR, 2.1; 95% CI, 1.7-2.5; p<0.001), and pseudoaneurysm formation (OR, 1.3; 95% CI, 1.1-1.6; p=0.003). Despite these differences, there was no significant sex-based difference in key clinical outcomes: excellent functional recovery at 90 days (OR 0.94; 95% CI 0.76-1.15 p=0.542), ischemic stroke recurrence at 180 days (OR 0.56 CI 0.23-1.3 p=0.213), or mortality (OR 0.83; 95% CI 0.47-1.48, p=0.529). Conclusion: In this large international cohort, we observed women with CeAD were younger, more likely to present with non-ischemic symptoms with distinct imaging features. These underscore the need for heightened clinical suspicion of CeAD in women presenting with atypical symptoms, even in the absence of ischemic deficits or conventional vascular risk factors, and suggest that sex-specific phenotyping may enhance diagnostic accuracy and early management.
