Correlation Between Intracranial Calcification and Extracranial Stenosis of the Internal Carotid Artery
We examined a population not selected for cerebral disease. This retrospective study contained 179 subjects aged 18 years and older from the Hawaii Diagnostic Radiology database. Extracranial internal carotid artery stenosis was determined using the absolute diameter, North American Symptomatic Carotid Endarterectomy Trial, and common carotid artery methods. Calcification was scored using the modified Woodcock method. A positive correlation between intracranial calcification and extracranial carotid stenosis was found using all three methods. Individuals with intracranial calcification were more likely to be older, have a ...

Using a CT Angiography Artificial Intelligence Carotid Plaque Morphology Model to Predict Stroke
The gold standard for determining carotid artery stenosis is to calculate stenosis using the North American Symptomatic Carotid Endarterectomy Trial criteria and ultimately plan for medical vs surgical management based on percent stenosis and symptomatic status. Few studies have assessed plaque morphology as an additive tool for stroke prediction. Our study uses an artificial intelligence software in conjunction with a patient's computed tomography (CT) scan of the neck to create a three-dimensional (3D) model of the carotid artery and assess plaque morphology including calcification, intraplaque hemorrhage, matrix, and pe...

The Impact of Full Collapse on the Risk of Ischaemic Stroke in Patients with Carotid Near Occlusion
Carotid near occlusion (CNO) is a severe carotid stenosis associated with a reduction in the calibre of the extracranial internal carotid artery distal to the stenosis.1 The risk of ipsilateral stroke in patients with CNO is a controversial issue. While a post hoc analysis of the North American Symptomatic Carotid Endarterectomy Trial (NASCET) and the European Carotid Surgery Trial (ECST) reported a lower risk of ipsilateral stroke for medically treated patients with CNO compared with patients with severe (70 –99%) carotid stenosis2, more recent studies have shown that the CNO recurrence rate may be higher.

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...

Embolic protection devices for carotid artery stenting: A network meta-analysis
CONCLUSIONS: PB deployment during CAS is superior to DF and DB in preventing distal embolization phenomena. However, no statistically significant difference in TIA and stroke rate was found among any of the analyzed EPD groups. Further research is warranted to investigate the association of embolic phenomena on imaging after CAS with clinically significant neurologic deficits.PMID:36394946 | DOI:10.1177/17085381221140616

Interleukin-6 Predicts Carotid Plaque Severity, Vulnerability, and Progression
CONCLUSIONS: Circulating IL-6 predicts carotid plaque severity, vulnerability, and progression. The 2.0 pg/mL cutoff could facilitate the selection of individuals that would benefit from anti-IL-6 drugs for stroke prevention.PMID:35713008 | DOI:10.1161/CIRCRESAHA.122.320877

One-Year Outcomes After Transcarotid Artery Revascularization (TCAR) in the ROADSTER 2 TRIAL
CONCLUSIONS: In patients with high risk factors, TCAR yields high technical success with a low stroke and death rate at one year. Further comparative studies to CEA are warranted.PMID:35381327 | DOI:10.1016/j.jvs.2022.03.872
