Hemodynamic instability can occur acutely after carotid angioplasty and stent placement (CAS). We performed this study to determine the frequency of hemodynamic in a series patients who underwent CAS analyze factors associated with development postprocedural events.We reviewed medical records angiograms 51 (mean age 68.3+/-8.9 years) for symptomatic (n=29) or asymptomatic (n=22) artery stenosis. Any episodes hypotension (systolic blood pressure <90 mm Hg), hypertension >160 bradycardia (heart rate <60 bpm) that occurred acute period were recorded. The effect demographic, clinical, intraprocedural, angiographic on subsequent was analyzed by logistic regression.The complications our patient as follows: hypotension, 22.4%; hypertension, 38.8%; bradycardia, 27.5%. Intraprocedural (odds ratio [OR] 14.6, P=0.024) history myocardial infarction (OR 14.1, P=0.04) independently predicted hypotension. Postprocedural intraprocedural 7.6, P=0.01) previous ipsilateral endarterectomy P=0.02). 74, P=0.001) 12, P=0.008). All events had resolved at conclusion intensive care unit monitoring 25.7 hours, range 18 43 hours).Postprocedural is frequent supports need settings suited expeditious management cardiovascular emergencies. Patients have evidence during procedure are highest risk.
