Among 62 women with pregnancy-associated CEAD, 40.3% experienced ischemic stroke symptoms, yet 92% had excellent functional recovery at 90 days after treatment.
Pregnancy-associated cervical artery dissection is uncommon but frequently presents with ischemic stroke; however, patients generally achieve excellent functional recovery with timely treatment.
Absolute Event Rate: 0% vs 0%
Background and Objectives: Pregnancy and the postpartum period increase the risk of cervical artery dissection (CEAD), a notable cause of stroke in young women. We aimed to describe the clinical presentation, imaging findings, and outcomes of CEAD occurring during pregnancy or shortly after delivery. Methods: We analyzed data from the STOP-CAD registry, a large international multicenter study of patients treated with antithrombotic therapy for non-traumatic CEAD between 2015 and 2021. This sub-study focused on women who were pregnant or within 12 weeks postpartum at the time of symptom onset. We assessed baseline clinical features, imaging results, acute stroke treatments, and functional outcomes. Results: Among 1,783 women in the registry, 62 (3.5%) had pregnancy-associated CEAD, with a median age of 34 years (IQR, 30-38). One-third had a history of migraine (33.9%), one-fifth had hypertension (21.0%), while other vascular risk factors were rare. Recent minor neck trauma was reported in 17.7%. Ischemic stroke symptoms occurred in 25 (40.3%) patients, and 23 (37.1%) had acute infarcts on imaging. However, most (59.7%) presented with non-ischemic symptoms. Vertebral artery dissections were more common than carotid dissections (62.9% vs. 48.4%), and 33.9% had multivessel involvement. Among patients presenting with ischemic stroke symptoms, 4 received thrombolysis and 7 underwent thrombectomy. Remarkably, 92% had excellent functional recovery (modified Rankin Score 0–1) at 90 days, and there were no stroke recurrences at 180 days. Conclusion: Pregnancy- and postpartum-associated CEAD is uncommon and associated with ischemic stroke in nearly half of patients. A history of migraine and hypertension may be potential risk factors. Despite the severity of presentation, most patients had favorable outcomes with timely treatment.
