Ultrasound (US) is one of the most important diagnostic tools available for the detection and evaluation of carotid stenosis. The case of a 70-year-old woman with recurrent right-sided amaurosis fugax presented here highlights the way in which tissue Doppler imaging (TDI) and contrast-enhanced US (CEUS) may aid in the diagnosis of carotid plaque vulnerability. Furthermore, the novel inverse fly...

A 64-year-old male presented with amaurosis fugax and presyncope as symptomatic 80%-in-stent restenosis (60 mm stent) 17 months after right internal carotid artery intervention (Fig. 1). Intraoperatively the carotid-stent was completely explanted (Fig. 2). Venous patch plasty was performed. He recovered early without any ischemic event. At follow-up 6 months later the patient remained completel...

A 72 year old woman complained of transient loss of vision in the left eye. She had undergone a left carotid endarterectomy 10 years previously. Reduced ophthalmic artery pressure was found on noninvasive carotid artery testing and cerebral angiography was performed. No lesion was evident in the carotid artery, but significant ophthalmic artery stenosis was identified. We report this case as sh...

A 52-year-old man presented with transient monocular blindness that was both spontaneous and exacerbated by exertion. Dynamic orbital CT revealed a delay in the perfusion of the left optic nerve head suggestive of a steal phenomenon. Subsequent selective arteriography demonstrated an arteriovenous fistula between the falx artery originating from the ophthalmic artery and the superior sagittal v...

There is eridence that microemboli responsible for araaurosis fugax may be atheromatous but it can elude ophthaimoscopic confirmation, because such emboii quickly fragment and disappear from view in the retinal vessels. This report documents 2 patients in whom fluorescein angiography of the retina provided evidence of microembolization after an attack of amaurosis although the fundus appeared n...

Conformal Predictors (CPs) are Machine Learning algorithms that can provide reliable confidence measures to their predictions. In this work, we make use of the Conformal Prediction framework for the assessment of stroke risk based on ultrasound images of atherosclerotic carotid plaques. For this application, images were recorded from 137 asymptomatic and 137 symptomatic plaques (symptoms are St...

Eighty-seven patients with either amaurosis fugax (40 patients) or hemispheric transient ischemic attacks (47 patients) were studied to determine whether the two symptom groups could be differentiated clinically and arteriographically. Clinical data assessed were age of patient, incidence of cardiac disease, and presence of claudication, hypertension, diabetes, and carotid bruits. Contrary to a...

PURPOSE To describe the time course of management of patients with amaurosis fugax and analyze differences in management by different specialties. METHODS Patients diagnosed with amaurosis fugax and subjected to carotid ultrasound in 2004-2010 at the Sahlgrenska University Hospital, Gothenburg, Sweden (n=302) were included in this retrospective cohort study, and data were collected from medic...
