Abstract

OBJECTIVE AND IMPORTANCE: Hemodynamic instability after carotid angioplasty and stenting is not well recognized. We report three patients who developed sustained hypotension in the postoperative period after successful carotid angioplasty and stent placement for internal carotid artery stenosis in the carotid sinus region. CLINICAL PRESENTATION: In two patients, hypotension was initially induced by inflation of the angioplasty balloon. The third patient developed hypotension after completion of the procedure. In all cases, the hypotension persisted for 18 to 33 hours after the procedure. During the postoperative period, two of these patients also developed sinus bradycardia, which, in one patient, was further complicated by a third- degree atrioventricular block. INTERVENTION: The hypotension was successfully treated by intravenous vasopressors or inotropic agents. No permanent neurological or cardiac sequelae were observed. CONCLUSION: Sustained hypotension with or without bradycardia may develop after carotid angioplasty and stent placement, presumably as a result of carotid sinus dysfunction. During the postoperative period, patients should be monitored in settings suited to expeditious management of cardiovascular emergencies.
