Carotid stenting or surgery and cognition: what do clinicians think?

A Columbia-led study published in JAMA found that opening blocked carotid arteries, either by stenting or by surgery (endarterectomy), did not improve cognitive function. The link between stenosis of the major brain arteries and cognitive decline is well known, but according to these data, restoring blood flow does not by itself reverse it. Details of the design and study population are best checked in the original paper; here we discuss the conclusions and what they mean. What shall we discuss: — Why might reopening the vessel fail to restore cognition: irreversible brain injury, other mechanisms of vascular cognitive impairment, or intervention that comes too late? — Should these findings change how we talk with patients about the goals of revascularization and what to expect from it, or do the indications stay the same, for example stroke prevention? — Have you noticed changes in cognitive status after carotid stenting or endarterectomy in practice, and how did you assess them? For USMLE and clinical practice, it helps to separate the indications for revascularization in ICA stenosis (stenting vs endarterectomy) from the question of whether the procedure affects cognition.
