Prolonged Hemodynamic Depression After Bilateral Carotid Angioplasty and Stent Insertion

ABSTRACT

Hemodynamic depression (hypotension and bradycardia) can occur during or after carotid angioplasty and stenting (CAS) due to stretching of the baroreceptors in the carotid sinus. The predisposing factors of hemodynamic depression have not been reported previously. In general, hemodynamic depression after CAS may continue for up to 3-5 days, but disappears within 7 days. We report herein a 65-year-old man with severe hemodynamic depression after sequential CAS, and discuss the possible causes from an anatomical point of view.
