Application of DSA & Ultrasonic Blood Rheography (Doppler) to Benign Paroxysmal positional Vertigo

Abstract

Fourteen cases of benign paroxysmal positional vertigo (BPPV) were studied with cervical circulation using DSA & Doppler. DSA study showed 7 abnormal cases out of 10cases of BPPV. The abnormal findings included 5 cases of stenosis and 5 cases of coiling and kinking in cervical vertebral arteries.
Doppler study showed that v e rtebral a. and also carotid a. had low volume and high laterality of cervical blood circulation in parameter of flow and velocity.
These findings suggest the cervical circulation disorder was o ne of background factors in pathogenesis of BPPV.
