Carotid artery stenting (CAS) has recently changed the status in the treatment of the extracranial carotid atheromasic disease. In recent years, evolution in both stents and protection devices as well as in carotid stenting techniques, has resulted in an important reduction in the rate of stroke in patients undergoing CAS procedures. Areas covered: The purpose of this article is reviewing the literature and summarizing the current evidence of the new available materials to underline the importance of the correct choice of the devices during the procedure. Expert commentary: Certainly a key issue in order to limit the periprocedural events to the lowest possible, is to select the appropriate device for the appropriate patient anatomy and clinical syndrome, the so called 'tailored approach'.

Tandem occlusion due to acute cervical carotid artery dissection should be promptly treated with thrombectomy for reperfusion. If the cervical lesion has reached severe stenosis or complete occlusion, balloon angioplasty and, in certain cases, carotid artery stenting should be performed before thrombectomy for the intracranial lesion. Angioplasty or stent placement is performed in the true lumen, but securing the placement is challenging when the true lumen cannot be determined.

Gadolinium contrast medium can serve as an alternative to iodinated contrast medium when the latter is unsuitable. In this report, we describe a case of a carotid-ophthalmic aneurysm in which angiograms were obtained using gadolinium contrast medium for flow-diverter stent placement due to the patient's history of bronchial asthma and hypersensitivity reactions to iodinated contrast medium. To enhance the visibility of gadolinium contrast medium, which typically provides lower contrast compared to iodinated contrast medium, we employed a contrast-enhancing and noise-reducing protocol on our image-guided therapy system.

: The external carotid artery (ECA) supplies blood to various facial and neck regions and may contribute to collateral cerebral perfusion. With the rise in carotid artery stenting (CAS) as a treatment for carotid stenosis, ECA overstenting has become a common procedure feature. This study aimed to assess the incidence, characteristics, and duration of facial pain following CAS, hypothesizing that ECA overstenting may contribute to facial pain.

Background And Purpose: The quantitative intra-arterial flow dynamics following percutaneous transluminal angioplasty and stenting (PTAS) for severe intracranial artery stenosis have never been investigated. We aimed to evaluate peritherapeutic intracranial artery flow dynamics following PTAS with quantitative magnetic resonance angiography (qMRA) to predict long-term stent patency.
Design: This is a prospective, single-center study.
