BACKGROUND AND PURPOSE: While there exists a substantial literature on the risk factors and clinical manifestations of cervical artery dissection (CeAD) including carotid and vertebral artery, little is known about postdissection recanalization. The goal of our study was to provide a descriptive analysis of CeAD and recanalization after dissection with neuroimaging follow up. METHODS: We retrospectively analyzed 51 consecutive patients with confirmed diagnoses of CeAD based on neuroimaging. Demographic data, risk factors, and dissection characteristics were recorded. Neuroimaging studies were performed at 0, 3, 6, and >6 months. RESULTS: Among 51 cases, the mean age of dissection (mean ± standard error) was 49.4 ± 1.92 years, and female comprised 58.8% of the patients. Extent of stenosis was 100% dissection in 37.3%, 51%–99% in 41.2%, and <51% in 21.5%. The most common presenting symptoms were headache (54.9%), neck pain (49.0%), and dizziness/gait imbalance (39.2%). The most common associated risk factors were recent history of trauma to the head and neck (41.2%) and hypertension (41.2%). In follow-up imaging, overall, 47.1% (24/51) had complete recanalization (CR), while 35.3% (18/51) did not; in the former group, 75% (18/24) recanalized completely during the first 6 months following symptom onset. A majority (84.3%) of the patients were discharged home, 15.7% were discharged to a facility, and no mortality was reported. Interestingly, location, type-/nature of dissection, and treatment did not statistically appear to influence the likelihood of recanalization. CONCLUSIONS: The recanalization of CeAD occurs mainly within the first 6 months after symptom onset, following which healing slows down. The study did not find an association between location, pattern, or nature of dissection on artery recanalization.
