OBJECTIVE The purpose of this study was to prospectively compare CT angiography with conventional angiography for detecting stenosis at the carotid bifurcation. SUBJECTS AND METHODS Thirty-five patients referred for evaluation of carotid artery disease were studied with conventional angiography followed by CT angiography 4-24 hr later. Seventy carotid(More)
Fifteen patients with liver metastases and one patient with hepatoma were treated by infusing 15 microns diameter plastic microspheres containing yttrium-90 into the hepatic artery. Twenty additional patients were screened but were found to be unsuitable for treatment. Follow-up angiography was done in 13 of the 16 treated patients. In five patients there(More)
The systolic blood pressure measured in the fingers and wrists by the spectroscopic method and in the arm by auscultation were correlated with angiographic evidence of organic arterial obstruction in 29 patients. The pressures also were measured in 14 normal people. Results in the normal people suggest that a difference of more than 15 mm. Hg between the(More)
Stenosis of the internal carotid artery reduces the flow velocity in the ophthalmic artery. Lowered velocity permits increased red cell aggregation and decreased red cell deformability which increases viscosity. Contrary to the theory of remotely originating emboli, this is an alternate hypothesis regarding transient attacks of ocular and cerebral ischemia.(More)
Despite the reported detrimental effects of international air travel on physical performance, a paucity of interventions have been scientifically tested and confirmed to benefit travelling athletes. Consequently, the aim of the present study was to examine the effects of sleep hygiene and artificial bright light interventions on physical performance(More)
Carotid endarterectomy is generally regarded as a durable repair, with a low incidence of postoperative thrombosis. However, unexpected, inexplicable occlusions and pressure-flow aberrations have been reported to occur during the period immediately after operation period. We studied 245 operative angiograms obtained during a series of 335 carotid(More)
The relationships between transient cerebral and retinal ischemic symptoms and brachiocephalic angiographic findings were studied in 464 patients. The arterial abnormalities were more often bilateral than the symptoms suggested. Normal angiographic appearances were common, although abnormal arteries in patients without related symptoms were also common.(More)
