E-029 symptomatic hemodynamic depression occurring before balloon inflation during carotid angioplasty/stenting

ConclusionDuring CAS, hemodynamic depression is caused by the stretch-induced stimulation of the carotid sinus baroreceptors located in the adventitial walls of the carotid bulb. This baroreceptor activation caused by balloon dilatation and stent deployment causes increased afferent signals to the caudal medulla by way of the carotid sinus and glossopharyngeal nerves. The medulla subsequently responds by increasing parasympathetic impulses and decreasing sympathetic vascular tone, which results in bradycardia and hypotension. Reported incidences of HD as well as individual hemodynamic parameters following CAS procedures vary widely in the literature, ranging from 5% to 76% for bradycardia, and 14% to 28% for hypotension. Our case highlights a rare case of symptomatic HD occurring just before carotid balloon inflation during carotid angioplasty/stent.DisclosuresJ. Lee: None.
