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.
