Recommended standards for analyzing and reporting on lower extremity ischemia were first published by the Journal of Vascular Surgery in 1986 after approval by the Joint Council of The Society for Vascular Surgery and the North American Chapter of the International Society for Cardiovascular Surgery. Many of these standards have been accepted and are used(More)
The Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts in the field of vascular ultrasonography (US) to come to a consensus regarding Doppler US for assistance in the diagnosis of carotid artery stenosis. The panel's consensus statement is believed to represent a reasonable position on the basis of analysis of available(More)
Young pinnipeds, born on land, must eventually enter the water to feed independently. The aim of this study was to examine developmental factors that might influence this transition. The ontogeny of metabolic rate and thermoregulation in northern fur seal, Callorhinus ursinus, pups was investigated at two developmental stages in air and water using(More)

Mycotic aneurysms are a fulminant infectious process frequently resulting in rupture and death if not properly treated. A review of the University of California, Los Angeles, medical records identified 10 patients with extrathoracic, extracranial mycotic aneurysms. In addition, a search of the English literature revealed 178 patients with 243 mycotic(More)
Milk ingested by mammalian offspring, coupled with offspring's utilization of this energetic investment, influences survival and growth. A number of studies have examined milk intake in otariids, but few have examined milk intake over the entire lactation period, and none has independently measured energy expenditure concurrent with milk intake. We(More)
PURPOSE To evaluate ultrasonography (US) and magnetic resonance (MR) angiography in the differentiation between occlusion and near occlusion of internal carotid artery (ICA). MATERIALS AND METHODS Consecutive patients with occlusion or near occlusion of ICA at catheter angiography and who underwent MR angiography and US were included. MR angiography and(More)
We treated 11 patients with congenital arteriovenous malformations (AVMs) with staged transcatheter arterial embolization of their lesions. In nine patients, the AVM involved an extremity. One patient had multiple pulmonary AVMs, another an AVM of the pancreas. Embolization was performed using polyvinyl alcohol sponge (Ivalon) particles and(More)
OBJECTIVE To report the structural and visual outcomes of eyes in which retinal detachment developed from retinopathy of prematurity (ROP) in the Early Treatment of Retinopathy of Prematurity (ETROP) Study. Method Infants in the ETROP Study with bilateral high-risk prethreshold ROP had 1 eye randomized to early treatment, with the fellow eye managed(More)
BACKGROUND Studies have shown that panoramic radiographs can capture images of calcified atheromas in the internal carotid artery (ICA) in some neurologically asymptomatic patients receiving routine dental care. However, the prevalence of these hemodynamically significant lesions--that is, those causing greater than 50 percent vessel lumen occlusion with(More)
