Research on hemodynamics of cerebral arteriovenous malformation by Doppler ultrasound.


Combined extracranial and transcranial Doppler (TCD) instruments were used to study the hemodynamics of 20 patients with cerebral arteriovenous malformation (AVM) proved angiographically. It was discovered that the flow velocities in AVM-feeding arteries and their proximal arteries were increased; the increase of flow velocities in feeding arteries close to… (More)
