ObjectivesThe natural course of unruptured vertebral artery dissection remains unclear. The clinical manifestation of unruptured vertebral artery dissection varies from headache, focal neurologic deficits caused by ischemia to subarachnoid hemorrhage with high mortality. The purpose of this study is to investigate the clinical course of unruptured vertebral artery dissection.
Methods:From March 2011 to April 2013, 7 patients with headache or nuchal pain by spontaneous vertebral artery dissection visited our institute were retrospectively reviewed. Their clinical data was obtained by medical records and radiologic studies including computed tomographic angiography, magnetic resonance imaging, magnetic resonance angiography and digital subtraction angiography.
Results:No patient experienced fatal outcome by subarachnoid hemorrhage or vertebrobasilar ischemia during follow-up period. Radiologic studies also did not show the evidence of subarachnoid hemorrhage or vertebrobasilar ischemia. Follow-up angiography showed the decreased size or disappearance of aneurysm in 3 patients.
Conclusion:This study suggests that the natural course of unruptured vertebral artery dissection is not aggressive. Patients with unruptured vertebral artery dissection could be managed with conservative treatment including anticoagulants and/or antiplatelet agents.
