In the present study we aimed to investigate the incidence of cervical artery dissection (CAD)-related stroke, its characteristics, and the clinical course.
Ischemic stroke is the most common presentation of CAD. Information regarding CAD-related stroke is scarce.
It is an observational study conducted in the city of Isfahan, Iran. Patients with a documented diagnosis of ischemic stroke were recruited during 2017-2019 and were classified based on ASCOD system. Then we approached patients with CAD-related stroke and their characteristics were analyzed considering the involved vessel (dissection of the internal carotid artery (ICAD) or vertebral artery (VAD)). Functional outcome and recanalization status were assessed after 1 year of follow-up.
Among 3630 ischemic stroke patients, 51 (1.4%) had CAD-related stroke (mean age: 41.83±12.59, 40.4% female, 28 and 19 ICAD and VAD cases, respectively). The crude incidence rate of CAD-related stroke was 1.20/100 000/year (0.66 /100 000/year and 0.45/100 000/year for stroke due to ICAD and VAD, respectively). A favorable outcome (mRS≤2) was present in 63.82% of the patients after 1 year of follow-up. Headache at the time of hospital admission was associated with a better follow up-mRS (β=-.67, 95% CI: -1.24, -0.10). Type of the medication (anticoagulant or double antiplatelet) was related neither to mRS nor recanalization results. No statistically significant differences were observed between ICAD and VAD. Trauma (27.7%), smoking (21.3%) and headache disorders/migraine (21.3%) were the most common reported risk factors among patients.
Here we found a crude incidence rate of 1.20/100 000/year for CAD-related stroke, with trauma as the most common risk factor. CAD-related stroke has a good long-term prognosis regardless of type of the involved vessel or the used medication. Further population-based studies with longer follow ups are recommended.
