Clinical Article Bilateral severe carotid artery stenosis or occlusion – cerebral autoregulation dynamics and collateral flow patterns

Abstract

Background. Bilateral severe obstruction of the internal carotid artery is a hemodynamically critical state. We aimed to (1) analyze dynamic cerebral autoregulation (DCA) in affected patients, and (2) to correlate DCA data with different collateral flow patterns. Methods. DCA was assessed noninvasively by transfer function analysis (phase shift) of… (More)
