A simple, practical method of applying incremental dynamic computed tomography (CT) to the imaging of 20 carotid bifurcations is described. The results are compared with those obtained by conventional carotid angiography and intravenous digital subtraction angiography (DSA). Conventional angiography provided additional information about the carotid bifurcation in only one of 14 cases, while inc...

A prospective, clinical study was performed on patients with suspected carotid artery disease to compare the accuracy of compression and suction ophthalmodynamometry with carotid artery stenosis as determined by arteriography. Results were analyzed with respect to current criteria for classification and determination of "significant" carotid artery disease. Although our results suggest that the...

Acute aortic dissection is a life-threatening condition requiring immediate assessment and therapy. Rarely, aortic dissection involves carotid arteries and manifest cerebral infarction. Here, we report a case of aortic dissection complicated with fatal cerebral infarction. A 83-year-old man, who suddenly suffered consciousness disturbance and right hemiparesis, was transferred to our hospital f...

A non-invasive method using continuous wave Doppler shift ultrasound and spectral analysis was used as a screening test for severe carotid artery disease in patients undergoing cardiopulmonary bypass operations. One hundred and eighty-eight patients were examined before cardiac surgery (91 for ischaemic heart disease, 17 for ischaemic heart disease and valve replacement, 66 for valve replacemen...

A 39-year-old man was referred to the vascular surgeons with a right-sided cervical mass, palpitations, headaches and sweating. He had presented with abdominal discomfort 12 months earlier. Investigations had revealed a gastrointestinal stromal tumour (GIST) and left adrenalectomy. CT of the neck with contrast demonstrated a large right carotid paraganglioma, extending superiorly from below the...

A prospective, clinical study was performed on patients with suspected carotid artery disease to compare the accuracy of compression and suction ophthaimodynamometry with carotid artery stenosis as determined by arteriography. Results were analyzed with respect to current criteria for classification and determination of "significant" carotid artery disease. Although our results suggest that the...

OBJECTIVE Although many studies have shown that carotid intima-media thickness (IMT) is associated with coronary artery disease (CAD), it remains inconclusive whether assessment of carotid IMT is useful as a screening test for asymptomatic but severe CAD in diabetic patients. RESEARCH DESIGN AND METHODS A total of 333 asymptomatic type 2 diabetic patients without history of CAD underwent exer...

BACKGROUND Genetic cascade screening for heterozygous familial hypercholesterolemia (FH) revealed that 15% of individuals given this diagnosis do not exhibit elevated low-density lipoprotein cholesterol (LDL-C) levels. We assessed whether cardiovascular risk for these individuals differs from that of hypercholesterolemic FH heterozygotes and unaffected relatives. METHODS AND RESULTS Individua...

conclusions in cases of unusual vascular lesions, metabolic diseases must be considered. in homocystinuria, early diagnosis and treatment are important. blood homocysteine levels can be returned to normal, and some complications can be prevented. introduction homocystinuria is a hereditary disease caused by a defect in the enzymes involved in metabolizing methionine. homocystinuria can influenc...
