Predictors of unfavorable outcome in stent-assisted coiling for symptomatic unruptured intracranial spontaneous vertebral artery dissecting aneurysms (uis-VADAs): results from a multicenter study

To evaluate predictors of unfavorable outcome in stent-assisted coiling for symptomatic unruptured intracranial spontaneous vertebral artery dissecting aneurysms (uis-VADAs) based on 608 reconstructed lesions in 30 medical centres.A total of 608 patients (male:female=479:129; mean age, 53.26±10.26 years) with 608 symptomatic uis-VADAs underwent reconstructive treatments using stent(s) with coils between January 2009 and December 2015.
