Abstract Introduction Intracranial internal carotid artery calcifications (ICAC), a frequent finding on imaging studies, are predictive of future stroke risk in population-based studies. The clinical significance of this observation among ischemic stroke patients is however less clear. In this study, we analyzed ICAC burden in relation to vascular risk factor profile, stroke etiology, and extent of craniocervical vascular calcifications in a consecutive series of ischemic stroke patients. Methods The burden of ICAC was determined both on noncontrast CT and CT-angiography source images by semiquantitative scoring algorithms. The distribution of vascular risk factors, etiologic stroke subtype, and calcification burden in other craniocervical arteries was assessed among patients with no ICAC, mild–moderate ICAC, and severe ICAC. Results Of 319 patients included into the study, 28 % had no ICAC, 35 % had mild–moderate ICAC, and 37 % had severe ICAC on CT angiography. Independent factors associated with ICAC burden in multivariate analysis included age (p

Association between extra- and intracranial calcifications of the internal carotid artery: a CBCT imaging study.
This study aimed to evaluate the association between the extracranial and intracranial calcification depiction of the internal carotid artery (ICA), incidentally found in CBCT examinations in adults, and to discuss the conspicuous clinical implicatio

Clinical and imaging features associated with an increased risk of early and late stroke in patients with symptomatic carotid disease.
The aim of this review was to identify clinical and/or imaging parameters that are associated with an increased (decreased) risk of early/late stroke in patients with symptomatic carotid disease. IN THE FIRST 14 DAYS: Natural history studies suggest

Emergency cervical internal carotid artery stenting in combination with intracranial thrombectomy in acute stroke.
In past years, thrombectomy has become a widely used procedure in interventional neuroradiology for the treatment of acute intracranial occlusions. However, in 10-20% of patients, there are additional occlusions or stenotic lesions of the ipsilateral

Internal carotid artery stenting for intracranial atherosclerosis.
Intracranial atherosclerotic disease is a significant cause of stroke in the United States. Much like coronary atherosclerosis, this disease leads to arterial stenosis secondary to the buildup of lipid-based plaques in intracranial vessels. Ischemic

Intra-arterial treatment of patients with acute ischemic stroke and internal carotid artery occlusion: a literature review.
Acute ischemic stroke (AIS) due to internal carotid artery (ICA) occlusion has a poor prognosis if treated by intravenous thrombolysis. Intra-arterial (IA) treatment is a promising alternative. However, its effectiveness is still unproven.

Ocular Image and Haemodynamic Features Associated with Different Gradings of Ipsilateral Internal Carotid Artery Stenosis.
To analyse the changes of ocular haemodynamics and morphology in Chinese patients with internal carotid artery (ICA) stenosis in the current study.

Carotid Artery Stenosis with Acute Ischemic Stroke: Stenting versus Angioplasty.
When a patient with carotid artery stenosis presents emergently with acute ischemic stroke, the optimum treatment plan is not clearly defined. If intervention is warranted, and open surgery is prohibitive, endovascular revascularization may be perfor

Emergency carotid artery stenting in patients with acute ischemic stroke due to occlusion or stenosis of the proximal internal carotid artery: a single-center experience.
The feasibility, safety and effectiveness of emergency carotid artery stenting (eCAS) in patients with acute ischemic stroke (AIS) due to proximal internal carotid artery (ICA) stenosis or occlusion are still controversial. In this study we analyzed

Severe symptomatic intracranial internal carotid artery stenosis treated with intracranial stenting: a single center study with 58 patients.
We aimed to investigate the safety and effectiveness of intracranial stenting in a population with severe (≥ 70%) symptomatic intracranial internal carotid artery (ICA) atherosclerotic stenosis.

Blood pressure variability and stroke outcome in patients with internal carotid artery occlusion.
The aim of this study was to evaluate the relationship between arterial blood pressure (BP) variability during the acute phase and the 3-month outcome in ischemic stroke patients with internal carotid artery (ICA) occlusion.
