英文摘要 | The detection of extra-and intracranial disease of the vascular system using duplex and transcranial Doppler is a highly convenient technique as it can be performed at the bedside, is non-invasive and easily repeatable, has a high temporal resolution and is cost effective. Quantification of the volume flow rate may allow a more accurate and better understanding of the hemodynamics in variety of different clinical circumstances. This report describes a case of arteriovenous malformation (AVM) presenting with repeated incidences of dizziness. Duplex sonography revaled a significant increase in blood flow volume (>1, 000 ml/min) in both common carotid and internal carotid arteries. Significantly increased blood flow volumes were noted in these arteries as an isolated finding on routine duplex sonography examination in otherwise normal subjects, which may indicate the existence of asymptomatic AVM. |
