The evaluation of medical imaging to the diagnosis of extracranial carotid artery stenosis with ischemic cerebrovascular disease
Abstract：Purpose To estimate the value of the medical ima ging in theevaluation of the extracranial carotid artery stenosis. Me thods 15 patients, 30 carotid arteries were studied with Do ppler ultrasound(DUS), MR angiography(MRA). CT&MRI of the brain was done at the same time . 5 patients were also examined by CT angiography (CTA). The result i n 4 patients was compared with images obtained with digital subtraction angiogra phy (DSA). 6 patients with severe stenosis received carotid endarterectomy. Results 30 carotid arteries studied included mild stenosis in 8, moderate in 6, severe in 8, normal in 6 and occlusion in 2. In 8 cases of caroti d arteries with severe stenosis, there were more infarction lesions revealed on the ipsilateral narrowing carotid artery. The larger volume of the middle cerebr al artery distribution infarction followed the occlusion of the carotid artery o n the ipsilateral side in 2. Plaques were well delineated in CTA, and confirmed by operation. Conclusions There was close relationship between the carotid artery stenosis and cerebral infarction. The combined use of DUS, M RA, and CTA played an important role in the screening, diagnosing, and monitorin g of the carotid artery stenosis.
