Abstract: © 2017 Elsevier Inc. Purpose Cavernous sinus dural arteriovenous fistula (CSDAVF) causes hemodynamic disturbance in the arteries, which is detected by carotid Doppler sonography (CDS). The objective of the study was designed for validation of CDS in the diagnosis of CSDAVF. Material and methods 42 CSDAVF patients confirmed by angiography were enrolled. All patients were performed CDS before angiography. Evaluations of CDS parameters were compared with control subjects. Results The ECA resistive index (RI) shows the best performance. The highest yield shown on left ECA RI and increased from 78.6% to 91.7% on malignant-typed. Conclusion CDS may be beneficial as the screening tool for CSDAVF.
