Transcranial Doppler arteriography--a technical note

Transcranial Doppler (TCD) evaluation of the intracranial vessels was performed in sixty-six patients, 51 of whom received conventional angiography either prior to or subsequent to the ultrasonic arteriogram. Of the 14 patients evaluated for arteriovenous malformations (AVMs), TCD indicated the existence of the AVM in 10 cases. Of those 10 cases, 9 correlated with angiography. Twenty-one patients with aneurysms were evaluated with TCD and only 2 were detected. Twenty-three patients suspected of having ischemic disease were evaluated with TCD, which indicated the presence of stenosis in 21 patients. Twenty of those patients received conventional angiography, with 18 demonstrating significant stenosis.
