Abstract:
A large percentage of patients with cerebral arteriovenous malformation (AVM) show focal neurological signs or a history of intracranial hemorrhage. The present study used transcranial Doppler sonography to assess the clinical significance of hemodynamic disturbances in the intracranial arteries of patients with an AVM. 12 patients with untreated AVMs were examined by clinical, angiography, CT Scanning, and with transcranial Doppler sonography (blood flow velocity measurement in main intracranial arteries). A pathological increase in blood flow velocity was frequently found in AVM feeding arteries. AVM size was a poor predictor of pathological transcranial Doppler results.
