Abstract
Objective To investigate the clinical significance of contrast- enhanced ultrasound (CEUS) in the treatment of carotid artery stenosis with carotid artery angioplasty with stenting(CAAS).Methods Before and after treatment with CAAS,26 patients with extra cranial carotid stenosis were examined by DSA CEUS and digital subtraction angiography (DSA).Stenosis rates and vessel diameter based on CEUS and DSA were calculated and compared by t- test.The assessment of CEUS and DSA in the treatment of carotid artery stenosis with CAAS was performed by kappa test.Results There was a significant difference between stenosis rates calculated by CEUS before CAAS(83.12± 16.23％) and after CAAS(15.32± 8.51％) (t=18.86,P＜0.01).There was a significant difference between stenosis rates calculated by DSA before CAAS (81.32± 13.63％) and after CAAS (13.11 ± 6.72％) (t=18.86,P＜0.01).There was a significant difference between vessel diameters before CAAS (1.51± 0.61mm) and after CAAS(4.36± 0.55mm) (t=-17.69,P＜0.01).The kappa test showed that not only in 24 stenosis on proximal segment but also in 15 stenosis on dividing segment,the CEUS and DSA indicated very good consistency(Kappa＞0.75).Conclusion CEUS is an appropriate method in examination of extracranial carotid artery stenosis, preoperative evaluation and postoperative follow-up.CEUS may be used instead of DSAin patients unable to achieve DSA examination.关键词
