BACKGROUND AND PURPOSE: We investigated the predictors and time course for recanalization after vertebral artery dissection. METHODS: We prospectively studied 61 consecutive patients with confirmed diagnoses of vertebral artery dissection without intracerebral hemorrhage. Neuroimaging and clinical follow-up were performed at presentation and at 3, 6, and 12 months. RESULTS: We included 61 patients with confirmed vertebral artery dissection; 19 were evaluated and followed up with conventional angiography, 24 with MR angiography, and 18 with CT angiography. Fifty-one patients had a stenotic dissection, 7 had an occlusive dissection, one had a double-lumen image, and 2 had a pseudoaneurysm. The estimated rate of complete recanalization after vertebral artery dissection was 45.9% at 3 months, 62.3% at 6 months, and 63.9% at 12 months. We found no association between outcome and complete or partial recanalization nor did we find any factors associated with recanalization. CONCLUSIONS: These results suggest that recanalization of vertebral artery dissection occurs mainly within the first 6 months after the onset of symptoms regardless of the location or pattern of the dissection.
