E-CEA might have a decreasing influence on BRS, leading to increased sympathetic activity. Investigations of the longer-term effects of impaired BRS are warranted. These findings should be interpreted with caution, noting the limitation of an absent control group.
E-CEA and C-CEA have different effects on BRS. This is associated with an altered haemodynamic behaviour after E-CEA and C-CEA, respectively. These findings are likely the result of carotid sinus nerve interruption during E-CEA and preservation with C-CEA.
E-CEA appears to be associated with greater postoperative sympathetic activity and vasodilator requirements than C-CEA, findings likely related to sacrifice of the carotid sinus nerve during E-CEA but not C-CEA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
