Abstract
Abstract
Objectives
Ischemic stroke is the most common presentation of cervical artery dissection (CAD). Information regarding CAD-induced stroke is scarce, especially in the Middle East. Here we investigated the incidence of CAD-induced stroke, its characteristics, and the clinical course in central Iran.
Methods
This is an observational study conducted in the city of Isfahan, Iran. We recruited patients with ischemic stroke during 2017–2019. We analyzed characteristics of the CAD-induced stroke patients with regards to the involved vessel (internal carotid artery dissection (ICAD) or vertebral artery dissection (VAD)). We assessed functional outcome (modified Rankin Scale [mRS]) and recanalization status after 1 year of follow-up.
Results
Among 3630 ischemic stroke patients, 51(1.4%) had CAD-induced stroke (mean age: 41.8 ± 12.6; 40.4% female; 28 and 19 ICAD and VAD cases, respectively). The crude incidence rate of CAD-induced stroke was 1.20/100,000/year (0.66/100,000/year and 0.45/100,000/year for strokes due to ICAD and VAD, respectively). mRS ≤ 2 was present in 63.8% of the patients after 1 year of follow-up. History of exercise during the last days before stroke occurrence was associated with a better follow-up mRS (β = -3.1, p-value: 0.037). Administration of anticoagulant or double-antiplatelets was related neither to mRS nor recanalization results. Trauma (27.7%), smoking (21.3%), and headache disorders/migraine (21.3%) were the most common reported factors.
Conclusion
We found a crude incidence rate of 1.20/100,000/year for CAD-induced stroke. Trauma, smoking, and headache disorders were the most common reported factors among our patients. CAD-induced stroke had a favorable long-term prognosis regardless of the type of the involved vessel or the used medication.
