The evaluations of the effect of stent implantation using multimodal computed tomography in ischemic cerebrovascular patients / 中国神经精神疾病杂志

ABSTRACT

Objective To evaluate the effect of stent implantation using Multimodal CT in patients with MCA and ICA stenosis. Methods Twenty-six patients with ischemic cerebrovascular disease who received MCA or ICA stent implantation in ChongQing xinqiao Hospital were recruited. Multimodal Stroke Assessment Using CT Score (MOSAIC) was used to evaluate the Neuroimaging data before stent implantation and Alberta Stroke Program Early CT Score (ASPECTS) to evaluate the time to peak (TTP) of CTP before and after stent implantation. Results Patients were divided into 4 groups based on scores 4 scores, 5 scores, 6 scores, and 7 scores groups. the improvement degree was increase by 31.7%±14.17%、38.6%±15.73%、43.3%±10.3%、358.6%±13.45% in 4 scores, 5 scores, 6 scores, and 7 scores groups, respectively. The paired t test demonstrated that there were a statistically significant difference among four groups(H=10.673, P <0.05). Preoperative MOSAIC score was positively correlated with the improvement of ASPECT score for TTP, with a correlation coefficient of 0.579 ( P <0.002). Conclusions Multimodal CT is a sensitive assessment for the evaluation of ischemic cerebrovascular disease and patients with a higher MOSAIC score may benefit more from stent implantation.
