INTRODUCTION: The management of intracranial artery dissection (IAD) has not been established, partly because the long-term course of the disease is not well-known. We retrospectively investigated the long-term course of IAD without subarachnoid hemorrhage (SAH) as an initial clinical presentation.
METHODS: Of 147 consecutive spontaneous first-ever IAD patients hospitalized between March 2011 and July 2018, 44 with SAH were excluded, and the remaining 103 were investigated. We divided the patients into two groups: Recurrence group as those with recurrent intracranial dissection >1 month after the initial dissection, and Non-recurrence group as those without them. Clinical characteristics were compared between those two groups.
RESULTS: The mean follow-up period was 33 months from the initial event. Recurrent dissection occurred in 4 patients (3.9%) >7 months after the initial dissection, none of whom were on antithrombotic treatments at recurrence. Three had ischemic stroke and the other had local symptoms [range: 8 to 44 months]. Nine (8.7%) had an ischemic stroke within 1 month of the initial event. There was no recurrent dissection between 1 and 7 months after the initial event. There was no significant difference in baseline characteristics between Recurrence and Non-recurrence groups.
CONCLUSIONS: Four out of the 103 (3.9%) IAD patients had recurrent IAD >7 months after the initial event. IAD patients should be followed up for more than a half year after the initial event, with consideration given to the recurrence of IAD. Further research is needed on recurrence prevention measures to IAD patients.
