Abstract:
Objective To determine collateral circulation in patients with acute ischemic stroke using capillary index score (CIS)in order to evaluate the prognosis of endovascular treatment. Methods From January 2013 to December 2015,46 consecutive patients with acute ischemic stroke treated with endovascular treatment at the Department of Neurology,Central Hospital of Baotou were enrolled retrospectively. Angiography was performed before endovascular treatment in order to complete CIS score. The patients were divided into a good prognosis group (n = 21)and a poor prognosis group (n = 25)according to the modified Rankin scale (mRS)scores. Univariate analysis was used to compare the baseline data and the clinical data of the two groups,including age,sex,history of diabetes,pretreatment systolic blood pressure,conducting intravenous thrombolysis or not,time from ictus to intravenous thrombolysis,National Institutes of Health Stroke Scale (NIHSS)score,Alberta stroke program early CT score (ASPECTS),vascular filling,time from onset to revascularization,and postoperative vascular recanalization (the modified Thrombolysis in Cerebral Infarction [mTICI]). Multivariate analysis was used to analyze the effect of CIS score on good prognosis. Results There were no significant differences in age,sex,history of diabetes,pretreatment systolic blood pressure,conducting intravenous thrombolysis or not,time from ictus to thrombolysis,and number of mechanical thrombectomy between the good prognosis group and the poor prognosis group (all P > 0. 05). There were significant differences in the NIHSS score (15 ± 3 vs. 19 ± 4),ASPECTS score (8 [7,10]vs. 6 [5,8]),filling well 85. 7% (18 / 21)vs. 44. 0% [11 / 25]),time from ictus to recanalization (363 ± 42 min vs. 398 ± 53 min),and postoperative vascular recanalization (mTICI≥Ⅱb)(100. 0% [21 / 21]vs. 68. 0%[17 / 25];all P < 0. 05). CIS (OR,8. 600,95% CI 2. 670 -33. 800)and mTICI grade (OR,5. 720, 95%CI 12. 170-22. 300)were significantly associated with the prognosis. Conclusion The CIS score can be used to evaluate brain perfusion. fCIS is closely associated with the good clinical prognosis. When screening the suitable patients for endovascular therapy,increasing the CIS score to evaluate the salvageable brain tissue is effective and feasible.
