Transcranial Doppler and Carotid Duplex Ultrasonography Findings in Bow Hunter's Syndrome

Abstract

Bow hunter's syndrome (BHS) is caused by transient vertebro-basilar ischemia on head rotation. We report a patient with BHS who was identified from dynamic changes to blood flow velocities in the posterior cerebral, basilar and vertebral arteries using carotid duplex ultrasonography and transcranial Doppler, simultaneously. Neurosonology appears to be useful for diagnosing and evaluating BHS.
