Clinical and radiographic natural history of cervical artery dissections.
ABSTRACT Cervical artery dissection (CADsx) is a common cause of stroke in young patients, but long-term clinical and radiographic follow-up from a large population is lacking.
Epidemiologic data, treatment, recurrence, and other features were extracted from the records of all patients seen at our stroke center with confirmed CAD during a 15-year period. A subset of cases was examined to provide detailed information about vessel status.
In all, 177 patients (mean age 44.0 +/- 11.1 years) were identified, with the male patients being older than the female patients. Almost 60% of dissections were spontaneous, whereas the remainder involved some degree of head and/or neck trauma. More than 70% of patients were treated with anticoagulation. During follow-up (mean 18.2 months; 0-220 months) there were 15 cases (8.5%) of recurrent ischemic events, and two cases (1.1%) of a recurrent dissection. About half of recurrent stroke/transient ischemic attack events occurred within 2 weeks of presentation. There was no clear association between the choice of antithrombotic agent and recurrent ischemic events. Detailed analysis of imaging findings was performed in 51 cases. Some degree of recanalization was seen in 58.8% of patients overall, and was more frequent in women. The average time to total or near-total recanalization was 4.7 +/- 2.5 months. Patients with complete occlusions at presentation tended not to recanalize.
This large series from a single institution highlights many of the features of CAD. A relatively benign course with low recurrence rate is supported, independent of the type and duration of antithrombotic therapy.

ABSTRACT: Cervical carotid dissection is more common in extracranical vessel: internal carotid artery dissection (ICAD) is typical, vertebral artery dissection is uncommon, common carotid artery dissection (CCAD) is rare and even a more rare cause of ischemic stroke. Cervical artery dissections account up to 20-25% of ischemic strokes in young patients. Isolated and spontaneous common carotid artery dissection without aortic damage is unique. Indeed in the Literature 8 cases were identified. MRI and CTA were the most commonly used for diagnosis and follow-up.Annali italiani di chirurgia 01/2014; 85. · 0.68 Impact Factor

ABSTRACT: Cervical artery dissections (CDs) are among the most common causes of stroke in young and middle-aged adults. The aim of this scientific statement is to review the current state of evidence on the diagnosis and management of CDs and their statistical association with cervical manipulative therapy (CMT). In some forms of CMT, a high or low amplitude thrust is applied to the cervical spine by a healthcare professional.Stroke 08/2014; · 6.02 Impact Factor
