Abstract:
Posterior circulation ischemia (PCI) is a common disease and frequent encountered disease in clinical practice. It refers to the transient ischemic attack and the cerebral infarction in vertebral-basilar artery system. Vertebral aretery atherosclerosis is one of the common causes of PCI. Imaging examinations for PCI include transcranial Doppler (TCD), digital subtraction angiography (DSA), computerized tomographic angiography (CTA), magnetic resonance angiography (MRA), color Doppler ultrasound (CDU) and so on. TCD can serve as initial screening tool in diagnosis of PCI. DSA is still thegold standardin diagnosis of vertebral-basilar abnormalities, although the operation injury and photography drugs poisonousness have not been resolved. CTA has almost the same defects as DSA, while MRA is noninvasive. Some researches have reposed that MRA can exaggerate the vertebral artery depression level. The inner diameter and hemodynamics of the vertebral artery can be accurately measured by CDU, and it can be seen as a noninvasive examination for PCI,which is direct, accurate, convenient and repeatable. It can provide positive evidence for diagnosis and treatment of PCI. This article reviews the progess of CDU in diagnosis of vertebral aretery atherosclerosis.
