This study validated the role of carotid duplex sonography in screening for DAVF in patients with pulsatile tinnitus. The criteria used for DAVF screening were low resistance index of the external carotid artery or occipital artery (OA). Patients then underwent head magnetic resonance imaging to confirm the diagnosis. Of the 155 patients with pulsatile tinnitus who were prospectively screened, 25 (16.1%) had a low resistance index in either the external carotid artery or occipital artery. All were proven to have DAVF. The diagnostic sensitivity, specificity, positive predictive value and negative predictive value were 96%, 100%, 100% and 98%, respectively. Thus, carotid duplex sonography focusing on low resistance indexes of the external carotid and occipital arteries may be a valuable tool in screening for DAVF in patients with pulsatile tinnitus. ? 2016 World Federation for Ultrasound in Medicine & Biology.[SDGs]SDG3Magnetic resonance imaging; Screening; Ultrasonic imaging; Ultrasonography; Arteriovenous fistulas; Early diagnosis; External carotid arteries; Negative predictive value; Occipital arteries; Positive predictive values; Pulsatile tinnitus; Stroke; Diagnosis; adult; artery resistance; Article; brain arteriovenous malformation; carotid duplex sonography; clinical article; controlled study; diagnostic accuracy; diagnostic value; dural arteriovenous fistula; echography; external carotid artery; female; human; imaging system; male; nuclear magnetic resonance imaging; occipital artery; predictive value; priority journal; pulsatile tinnitus; screening; sensitivity and specificity; tinnitus; validity; carotid artery disease; central nervous system malformation; complication; duplex Doppler ultrasonography; evaluation study; mass screening; middle aged; procedures; reproducibility; tinnitus; validation study; Carotid Artery Diseases; Central Nervous System Vascular Malformations; Female; Humans; Male; Mass Screening; Middle Aged; Reproducibility of Results; Sensitivity and Specificity; Tinnitus; Ultrasonography, Doppler, Duplexjournal article10.1016/j.ultrasmedbio.2015.10.013266143862-s2.0-84955305395
