ABSTRACT
OBJECTIVE:
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.METHODS:
A total of 608 patients (malefemale=479129; 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. Treatments and predictors of unfavorable outcomes were retrospectively analyzed.RESULTS:
Mainly, three methods were used to treat patients with uis-VADAs, including routine single-stent in 208 patients (such as Enterprise and others), new low-profile LVIS single stent in 107 patients, and multiple stents in 293 patients. During the median 66 months of clinical follow-up, 14 patients died, and 16 of the remaining 594 survivors had unfavorable outcomes (modified Rankin Scale score 3-5). The overall mortality rate was 2.3% (14/608), and the unfavorable outcome (mRS score 3-6) rate was 4.9% (30/608). Multivariate logistic regression analysis indicated that preprocedural ischemic infarctions (OR=3.78; 95% CI 1.52 to 9.40; p<0.01), diabetes mellitus (OR=3.74; 95% CI 1.31 to 10.68; p=0.01), and procedural complications (OR=14.18; 95% CI 5.47 to 36.80; p<0.01) were predictors of unfavorable outcome in the reconstructed VADAs.CONCLUSIONS:
This multicenter study indicated that preprocedural ischemic infarctions, diabetes mellitus, and procedural complications were related to unfavorable clinical outcomes in the reconstructed uis-VADAs.Key words
