P7 Objective: To assess the diagnostic efficacy of  echo-enhanced transcranial color coded duplexsonography (eTCCD) for  noninvasive evaluation of the intracranial vasculature in patients with  cerebrovascular symptoms.MATERIAL AND METHODS: We  prospectively evaluated 35 consecutive patients (10 women, 25 men, mean  age 58,8 ± 9,7) with eTCCD (galactose palmitic acid based  echo-enhancing agent) and digital subtraction angiography (DSA). All  patients were admitted to our neurology department for acute onset of  cerebrovascular symptoms.RESULTS: In 34/35 patients eTCCD  visualized the circle of Willis. In 15/17 patients with critical  symptomatic internal carotid artery obstruction (lumen diameter  reduction of &gt;85% or occlusion) eTCCD correctly identified collateral  flow patterns through the circle of Willis. DSA and eTCCD showed  MCA-occlusion in 4 patients. In one of these patients eTCCD correctly  identified a contralateral severe MCA-stenosis, which was first missed  by DSA but confirmed by angiographic reevaluation. In 1 patient eTCCD  missed occlusion of a M3-segment. In 2/3 patients eTCCD showed  intracranial ICA-stenosis. In 3 patients with symptoms suggestive for  basilar artery thrombosis DSA and eTCCD showed severe basilar stenosis  in 1 patient and intracranial vertebral artery occlusion in 2 patients.  DSA and eTCCD were normal in 3 patients with atypical intracranial  hemorrhages and in 1 patient with subarachnoid hemorrhage. In another  patient eTCCD correctly suggested a left parietooccipital AVM. DSA and  eTCCD were normal in 4 other patients.CONCLUSION: eTCCD  reliably detects occlusion, stenosis and collateral flow patterns of  the basal cerebral arteries in patients with cerebral ischemia. For  patients with cerebral hemorrhage our data are limited.
