| Abstract |
Carotid artery stenting (CAS) is associated with a higher risk of periprocedural stroke than carotid endarterectomy. For better patient selection, more accurate risk factors should be identified. The aim of this study was to determine whether expansive arterial remodeling can predict ischemic complications in patients undergoing CAS. This retrospective study included 82 patients with carotid stenosis treated by CAS. The plaque component was evaluated using MR plaque imaging before the procedure. Following the procedure, lesion assessment was performed using MRI diffusion-weighted imaging (DWI), and patients were classified as DWI positive or negative for comparison between groups. Fifteen patients were classified as DWI positive and 67 patients as DWI negative. The mean expansive remodeling rate was 1.76 ± 0.21 in the DWI-positive group and 1.35 ± 0.18 in the DWI-negative group (P < 0.001). Receiver-operating characteristic analysis revealed that the threshold for the expansive remodeling rate separating the two groups was 1.52 (area under the curve = 0.933). The positive predictive value of postoperative new DWI lesions in the high-intensity plaque associated with a high expansive remodeling rate was 64.3%, and the negative predictive value of the isointensity plaque associated with a low expansive remodeling rate was 97.8%. These values were higher than those of the plaque component alone (32.1% and 81.7%, respectively). This study revealed that expansive arterial remodeling is a strong risk predictor of ischemic complication in CAS. Expansive remodeling rate measurements are very simple and provide useful information for determining treatment strategies for patients with carotid stenosis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 June 2017.
All research outputs
#20,429,992
of 22,982,639 outputs
Outputs from Acta Neurochirurgica
#1,689
of 1,933 outputs
Outputs of similar age
#269,643
of 309,920 outputs
Outputs of similar age from Acta Neurochirurgica
#26
of 32 outputs
Altmetric has tracked 22,982,639 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,933 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 309,920 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 32 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
