BACKGROUND AND PURPOSE: Generally, the prognosis for cervical artery dissection (CAD) is uncertain. The recanalization rate of CAD can be up to 85% within 3 months. This study evaluates the variables that might affect recanalization and the role of recanalization as a predictor for neurological outcome.
PATIENTS AND RESULTS: This study prospectively included 38 patients with acute stroke following occlusion due to CAD (18 males, 20 females, median age 50.5 years, range 16-82). Vertebral and carotid dissections were equally distributed (19 carotid dissections). The recanalization rate was influenced by the presence of hypertension (p = 0.001). Outcomes were dependent on infarct location. Patients with lateral medullary infarction returned to functional independence (p = 0.026), while patients with deep hemispheric infarction tended to have a disabling stroke (p = 0.068). The presence of good collaterals seemed to influence functional independence (p = 0.03).
CONCLUSION: There seemed to be no relationship between outcome and the rate of recanalization following CAD. Recanalization appeared to be a spontaneous mechanism, which could have depended on the intrinsic condition of the vessels. Finally, neurological outcome was dependent on lesion localization and the presence of good collaterals.
