Prediction of Borderzone Infarction by CTA in Patients Undergoing Carotid Embolization for Carotid Blowout

摘要: BACKGROUND AND PURPOSE: Permanent common carotid artery and/or ICA occlusion is an effective treatment for blowout syndrome. Besides postoperative thromboembolic infarction, permanent may cause borderzone infarction when the collateral flow to deprived brain territory inadequate. In this study, we aimed test predictive value of CTA post–permanent in patients with MATERIALS METHODS: retrospective included 31 undergoing unilateral syndrome between May 2009 and December 2016. The vascular diameter circle Willis was evaluated using preprocedural CTA, risk graded as very high risk, intermediate low risk. RESULTS: performance readers9 consensus on predicting excellent, area under receiver operating characteristic curve 0.938 (95% confidence interval, 0.85–1.00). We defined positive sensitivity, specificity, value, negative were 100% (7/7), 62.5% (15/24), 43.8% (7/16), (15/15), respectively. interobserver reliability excellent (κ = 0.807). No significant difference curves found 2 readers (P .114). CONCLUSIONS: can be used predict after by measuring vessels Willis.
