Abstract



Objective


To monitor the sonographic course of spontaneous cervical artery dissections (sCADs) and investigate their recanalization and recurrence rates.



Methods


All consecutive patients with an MRI-proven sCAD were prospectively evaluated by neurovascular ultrasound (nUS) daily while in hospital, then monthly for the first 6 months after discharge and every 6 months thereafter, for a mean follow-up period of 58 months (range, 28–96 months).



Results


A total of 105 sCADs were detected in 76 patients: 61 (58.1%) involved the internal carotid artery and 44 (41.9%) the vertebral artery, while multiple sCADs were found in 4 patients (5.3%). Follow-up was obtained in 74 patients (97.3%, 103 vessels). The complete and hemodynamically significant (<50% stenosis) recanalization rates were 51.4% (53/103) and 20.4% (21/103). All but one complete recanalization occurred within the first 9 months. There were early recurrences (while in hospital) in 20 previously unaffected arteries (26.3%) and late recurrences in 2 arteries (2.7%), site of a previous sCAD. All patients (n = 6) with a family history of arterial dissection had a sCAD recurrence (4 early and 2 late) as opposed to 16 (22.8%) among those with no known familial disease (p < 0.001).
