Blood flow patterns are poorly understood despite their impact on arterial disease. (more…)
Helical and retrograde secondary flow patterns in the aortic arch studied by three-directional magnetic resonance velocity mapping
Helical and retrograde secondary flows have been recorded in the aorta, but their origins and movements in relation to the arch have not been clarified. We set out to do this using magnetic resonance velocity mapping.
Spiral blood-flow patterns in infrainguinal blood-vessels were observed at angioscopy in 54 patients who underwent peripheral vascular reconstruction; the endoluminal surface had spiral folds in 51 of 75 arteries examined. (more…)
