Clinical Predictors of Hyperperfusion Syndrome Following Carotid Stenting: Results From a National Prospective Multicenter Study.

Objectives: The aim of the HISPANIAS (HyperperfusIon Syndrome Post-carotid ANgIoplasty And Stenting) study was to define CHS rates and develop a clinical predictive model for cerebral hyperperfusion syndrome (CHS) after carotid artery stenting (CAS).

Background: CHS is a severe complication following CAS. The presence of clinical manifestations is estimated on the basis of retrospective reviews and is still uncertain.

Safety of Early Carotid Artery Stenting for Symptomatic Stenosis in Daily Practice.

Objective/background: In 2006, the American Heart Association recommended that for preference carotid endarterectomy (CEA) or, alternatively, carotid angioplasty and stenting (CAS) for symptomatic carotid artery stenosis should ideally occur within 14 days of an ischaemic event. The aim was to determine the safety of CAS according to those recommendations in daily practice.

Methods: A retrospective analysis was performed of all consecutive patients (2000-16), with ipsilateral carotid symptoms who underwent CAS for extracranial carotid stenosis ≥70%, who were previously included in a prospective database.
