Abstract
BACKGROUND Carotid angioplasty and stenting (CAS) is an accepted treatment to prevent stroke in patients with carotid artery stenosis. The purpose of this study is to identify risk factors for major complications after CAS. MATERIALS AND METHODS This is a prospective study that was conducted at Shiraz University of Medical Sciences in southern Iran from March 2011 to June 2014. Consecutive patients undergoing CAS were enrolled. Both standard- and high-risk patients for endarterectomy were enrolled. Demographic data, atherosclerotic risk factors, site of stenosis, degree of stenosis, and data regarding technical factors were recorded. Thirty-day stroke, myocardial infarction, and/or death were considered as the composite primary outcomes of the study. RESULTS A total of 251 patients were recruited (mean age: 71.1 ± 9.6 years; male: 65.3%). Of these, 178 (70.9%) were symptomatic, 73 (29.1%) were diabetic, 129 (51.4%) were hyperlipidemic, 165 (65.7%) were hypertensive, and 62 (24.7%) patients were smokers. CAS was performed for left internal carotid artery (ICA) in 113 (45.4%) patients. Fourteen (5.6%) patients had sequential bilateral stenting. Mean stenosis of operated ICA was 80.2 ± 13.8%. An embolic protection device was used in 203 (96.2%) patients. Pre- and postdilation were performed in 39 (18.5%) and 182 (86.3%) patients, respectively. Composite outcomes were observed in 3.6% of patients (3.2% stroke, 0% myocardial infarction, and 1.2% death). Left-sided lesions and the presence of diabetes mellitus were significantly associated with poor short-term outcome (p = 0.025 and p = 0.020, respectively). CONCLUSION There was a higher risk of short-term major complications in diabetic patients and for left carotid artery intervention.

Abstract
Object
Postprocedural hypotension and bradycardia are important complications of carotid artery stenting (CAS) and are referred to as hemodynamic instability (HI). However, the incidence and impact of HI on the short-term prognosis of patients have been of a large debate.
Methods
Twenty-seven patients were selected based on NASCET criteria, and they underwent CAS between September 2008 and September 2009. Continuous electrocardiography monitoring and supine blood pressure (BP) monitoring were performed before and after stent deployment and on the following day to detect HI, defined as systolic BP lower than 90 mm Hg or a heart rate lower than 60 bpm. Patients were asked to perform a Valsalva maneuver before and after stent deployment. The Valsalva ratios (VRs) along with other demographic and procedural data were documented and compared between patients with and without incidence of HI.
Results
Seventeen patients (63%) developed HI after CAS. The degree of stenosis was found to have a significant correlation with occurrence of HI (p < 0.006). No other risk factor or demographic data showed any correlation with HI. The VRs were significantly lower in the HI group compared with the non-HI group, indicating a significant autonomic dysfunction (p < 0.003). During follow-up, 1 patient (4.3%) developed major stroke, and the remaining patients were symptom free.
Conclusions
Hemodynamic instability occurs frequently after CAS, but it seems to be a benign phenomenon and does not increase the risk of mortality or morbidity in the short term. A VR at rest less than 1.10, baseline autonomic dysfunction, and degree of carotid artery stenosis can be used as measures for predicting HI after CAS.

Abstract
Angioplasty and stenting of the cervicocerebral arteries is a novel treatment for atherosclerotic stenosis, which has periprocedural complications. Data were collected prospectively from 2007 to 2009 in a multicenter cohort of patients undergoing interventions for cervicocerebral stenosis. Retrospective assessment of the 2003-2006 archives of the same interventionists and a review of their published work is the second part of this national survey. In 592 extracranial internal carotid artery angioplasty and stenting procedures in 581 patients (73% male; mean age, 63.4 + or - 7 years), transient ischemic attack, stroke, intracerebral hemorrhage, and death occurred in 1.7%, 1.7%, 0.34%, and 1.52%, respectively. In 114 extracranial vertebral artery angioplasty and stenting procedures in 110 patients (68% male; mean age, 65.3 + or - 6 years), transient ischemic attack and stroke each developed in 1 (0.92%) patient, but there was no intracerebral hemorrhage or death. In 70 intracranial angioplasty and stenting procedures in 67 patients (76% male; mean age, 68.5 + or - 8 years), transient ischemic attack, stroke, intracerebral hemorrhage, and death were observed in 1.4%, 8.6%, 1.4%, and 2.9%, respectively. The frequency of periprocedural complications in angioplasty and stenting of cervicocerebral arteries by our neurointerventionists was similar to that in developed countries.
