E-107 Carotid artery stenting in patients with symptomatic non-stenotic carotid artery disease - a case series
ConclusionsIn this case series performed over a 10-year period at a high-volume stroke center we show that CAS is safe and efficient in patients with SyNC. Previous studies have established safety and effectiveness of CES in patients presenting with SyNC, however there is a paucity of reports in the literature regarding the effect of CAS in this patient population. Recent guidelines have brought specific attention to high-risk plaque characteristics which suggest that plaque instability plays a major role in the onset of ischemic events, regardless of lumen narrowing. Advanced imaging techniques, such as Optical Coherence ...

Correspondence on "Unplanned readmission after carotid stenting versus endarterectomy: analysis of the United States Nationwide Readmissions Database" by Nazari et al
We read the article by Nazari et al1 comparing carotid endarterectomy and carotid artery stenting. Most of the patients in the article were asymptomatic patients. Asymptomatic carotid stenosis is considered one of the most significant causes of ischemic stroke. The management of asymptomatic carotid stenosis ranges from open surgical approaches to minimally invasive endovascular interventions and medical therapeutics.2 With the advances in the neurosurgical field within the last decade, various surgical interventions have emerged. However, to date, the evidence regarding the optimal interventional strategies for asymptomat...

P63 Carotid stenting versus carotid endarterectomy for symptomatic carotid web: a systematic review and meta-analysis
ConclusionsCEA and CAS have both been used to treat carotid webs although CAS is more commonly reported in the published literature. Both procedures appear highly effective at preventing recurrent stroke. The safety profile of both procedures is good with no deaths recorded.ReferencesOsehobo EM, Nogueira RG, Koneru S, et al.

E-019 tcar
ConclusionsOur analysis of a single-center cohort demonstrates that TCAR is a safe and effective treatment for symptomatic carotid stenosis, with a low perioperative stroke risk. The present study’s findings concur with the combined adverse outcome rate of 3.5% reported in the ROADSTER trial.Disclosures A. Bajaj: None. S. Monje: None. C. Ayala: None. J. Poggi: None. E.

Correlation between intracranial vertebral artery stenosis diameter measured by digital subtraction angiography and cross-sectional area measured by optical coherence tomography
Conclusion Measurement of the narrowest diameter was not a reliable predictor of the cross-sectional area of V4 stenosis. Larger studies are therefore needed to develop a new evaluation system based on V4 stenosis.

E-140 Single center case studies comprising of early carotid stenting in patients who present with ischemic strokes
ConclusionEarly carotid stenting should be considered, when waiting 4-6 weeks might not be a feasible option due to high risk of recurrent stroke. The rate of complications is lower than what has been published in case reports and metanalyses in the literature, likely due to improved periprocedural management of platelet activity and blood pressure. Our data suggests that early carotid stenting is feasible and should be considered an option in selected cases. Larger data sets will need to be analyzed to get a clear idea of the overall complication rate.ReferencesDen Hartog, A. G., et al. Delay to carotid endarterectomy in ...

P-004 30 day results of revascularization of extracranial carotid artery stenosis (recas) trial in mainland china
This study is registered, number NCT01994187. Results The trial enrolled 2762 patients (CAS group, n=1543; CEA group, n=1176; CEA+CAS group, n=43). The primary end point was achieved in 4.47% (69/1543) in patients treated with carotid artery stents, and 4.93% (58/1176) in patients treated with carotid endarterectomy, an absolute difference of 0.46%. Risks of any stroke (3.50% vs 3.32%) was higher in the stenting group than in the endarterectomy group, but the risks of any death (0.39% vs 0.51%) was lower in the stenting group than in the endarterectomy group. Nine procedural myocardial infarctions were recorded in the st...

Long term durability and outcomes of carotid stenting and carotid endarterectomy
Conclusions Although CAS may be more strongly associated with periprocedural stroke/death compared with CEA, it could be a good alternative to CEA in terms of long term durability and outcomes.

Carotid revascularization treatment is shifting to low volume centers
Conclusions A trend toward a lower proportion of patients with carotid stenosis being treated in high volume centers from 2005 to 2011 is concerning as these high volume centers had lower complication rates.

Carotid artery stenting in nonagenarians: are there benefits in surgically treating this high risk population?
Conclusions CAS in nonagenarian patients carried increased risk of perioperative ischemic events, compared with contemporary trial results in symptomatic and asymptomatic patients. Further, mean survival time postprocedure fell short of guidelines for receiving procedural benefit. Although larger scale multicenter research is needed, we recommend careful consideration of overall health status when contemplating stenting in nonagenarians.

P-020 Emergent Carotid Artery Stenting with or without Intracranial Tandem Occlusion Lesions Following Carotid Endarterectomy
Conclusion Emergent endovascular evaluation in the setting of acute post CEA thrombosis is a safe and timely treatment option, with the benefit of detecting and treating embolic intracranial lesions.
