To determine the role of transcranial doppler (TCD) in the evaluation of the vertebrobasilar circulation, we compared the results of TCD with intraarterial digital subtraction angiography (DSA) in 20 patients with vertebrobasilar ischaemia (VBI). TCD had a sensitivity of 87%, a specificity of 80%, a positive predictive value of 93% and a negative predictive value of 67%. It was also able to give functional data when combined with arteriography and correctly identified the main pathology in 92… CONTINUE READING
