Abstract

Obstructions in the extracranial cerebral arteries can be detected noninvasively by directional Doppler ultrasound technique. There are two types of Doppler technique, indirect and direct. The indirect test is based on measurement of flow direction in supraorbital or frontal arteries and responses to superficial temporal, facial, infraorbital and common carotid artery compression. In this study, the results of cerebrovascular Doppler examination were compared with cerebral angiographic findings in five patients of moyamoya disease. These patients were suspected of having extracranial carotid occlusive diseases according to cerebrovascular Doppler studies and the diagnoses were confirmed finally by the transfermoral carotid angiography. The results of supraorbital study and cerebral angiography were correlated in all six cases of internal carotid artery stenosis with more than 60% of narrowing in diameter, but the results of frontal study correlated in five of sis cases. Therefore it is suggested that the Doppler study can be used in screening the patients with the risk of stroke, without employing complicated, expensive and sometimes life thratening angiographic procedure.
