Multicenter Study
Socioeconomic characteristics of patients undergoing ambulatory diagnostic cerebral angiography in four US States.
Several groups have demonstrated the safety of ambulatory cerebral angiography, with no patients experiencing complications related to early discharge. Although this practice appears to be safe, the socioeconomic characteristics factoring in the selection of the patients have not been investigated. ⋯ Access to ambulatory diagnostic cerebral angiography appears to be more common for patients with private insurance and less comorbidities, in the setting of lower volume hospitals. Further investigation is needed in the direction of mapping these disparities in resource utilization.

Contrast-enhanced ultrasound imaging of the carotid arteries (CECU) permits direct, real-time visualization of neovascularization in atherosclerotic plaques and is a confirmed predictor of unstable atheromatous lesions. The aim of the study was the assessment of a new, automatically measured index of intensity in quantitative estimation of the contrast flow through the carotid plaque (till now assessed only visually). ⋯ The assessment of the index of intensity is a novel, simple and automatic method to estimate the degree of contrast flow through the carotid plaque. The values of the index of intensity correlate with the contrast flow through the atherosclerotic plaque, but not with its calcification.
