Bilateral aberrant internal carotid arteries with bilateral persistent stapedial arteries and bilateral duplicated internal carotid arteries.
A 5-year-old boy was evaluated for a left retrotympanic mass found at otoscopy. Subsequent petrous bone CT and MR angiographic examinations demonstrated bilateral aberrant internal carotid, bilateral stapedial artery persistence, and bilateral duplicated internal carotid arteries. Imaging findings and their clinical relevance are discussed. A second case of unilateral aberrant internal carotid ...
متن کاملBilateral "hypoplasia" of the internal carotid arteries.
Bilateral hypoplasia of the internal carotid arteries is a rare congenital anomaly. We present the case of a 62-year-old man with this rare condition. The findings from the plain computed tomography and computed tomography angiogram are described in this report. The common collateral pathways associated with bilateral hypoplasia of the internal carotid arteries, the clinical presentation and cl...
متن کاملMeasurement variability in duplex scan assessment of carotid atherosclerosis.
BACKGROUND AND PURPOSE The reproducibility of duplex scan measures of carotid atherosclerosis was evaluated as part of a study assessing the prevalence of carotid disease in elderly adults. METHODS Doppler measures of blood flow velocity were used to evaluate disease severity, and extent of carotid plaque was scored from the B-mode image. A reader assigned a grade from 0 to 3 to each of seven...
متن کاملDo carotid bruits predict disease of the internal carotid arteries?
A carotid bruit is often thought of as a reliable sign of extracranial carotid artery disease. In addition finding a bruit may precipitate a referral to hospital. Carotid endarterectomy has now been shown to be beneficial in patients with symptomatic carotid territory ischaemia and 70-99% stenosis of the relevant carotid artery, therefore it is important that such patients are detected and refe...
متن کاملCarotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion
Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
