INTRODUCTION: Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, stenting plays an important role as an alternative treatment modality, especially in high-risk patients. The actual safety profile associated with stenting procedures is probably better than that reported by randomized controlled trials. AIM: To assess the safety of stent implantations in extracranial arteries supplying the brain, and also to identify risk factors associated with this procedure...

BACKGROUND AND PURPOSE: Carotid stenosis (CS) with intraluminal carotid artery thrombus (ICAT) is rare but ominous finding. The optimal treatment modality is unclear. The aim of this study was to analyze the feasibility and outcome of acute endovascular intervention and delayed elective endovascular therapy after initial anticoagulation in these delicate cases. Moreover, both treatment points were compared and several parameters discussed to facilitate the determination of the optimal time modality in future cases...

Pseudoaneurysms of the cervical internal carotid artery are rare and usually result from trauma, infection, or rarely spontaneously. They harbor potential risk of life-threatening hemorrhage and warrant immediate management. Endovascular treatment in the form of stent placement and coiling is a well established technique for dealing with both intracranial and extracranial pseudoaneurysms. We present a case of a child who presented with fever, neck swelling, dysphagia, and respiratory distress in emergency for which clinical diagnosis of a neck abscess was made...

BACKGROUND AND PURPOSE: Because magnetic resonance imaging (MRI) focuses on the morphological characteristics of carotid artery plaques, its diagnostic value with respect to plaque vulnerability is limited. We examined the correlation between N(ε)-(carboxymethyl)lysine (CML), a main chemical structure of advanced glycation end-products, and the vulnerability of plaques visualized on MRI scans. MATERIALS AND METHODS: We enrolled 43 patients who had undergone carotid artery stenting (CAS) for carotid artery stenosis; all underwent MRI studies, including black-blood MRI and diffusion-weighted imaging (DWI)...

The horizontal stenting technique facilitates endovascular treatment of wide-necked bifurcation intracranial aneurysms. Previous literature shows, however, that subsequent coil embolization at initial treatment results in incomplete obliteration in many cases. The authors present two consecutive cases of wide-necked large bifurcation aneurysms to describe an additional coil embolization technique following horizontal stenting. The patients were a 53-year-old female with an unruptured internal carotid artery terminus aneurysm and a 57-year-old female with a recurrent basilar artery tip aneurysm...

OBJECTIVE/BACKGROUND: Several plaque and lesion characteristics have been associated with an increased risk for procedural stroke during or shortly after carotid artery stenting (CAS). While technical advancements in stent design and cerebral protection devices (CPD) may help reduce the procedural stroke risk, and anatomy remains important, tailoring stenting procedures according to plaque and lesion characteristics might be a useful strategy in reducing stroke associated with CAS. In this descriptive report of the ongoing Asymptomatic Carotid Surgery Trial-2 (ACST-2), it was assessed whether choice for stent and use or type of CPD was influenced by plaque and lesion characteristics...

BACKGROUND: It is essential that patients undergoing carotid artery stenting (CAS) receive optimal antiplatelet inhibition. Although a reduction in platelet reactivity and improved clinical outcomes occur when using adjunctive cilostazol with dual antiplatelet therapy, this can lead to an increased risk of hemorrhagic complications. Therefore, our current study examined patients undergoing CAS and evaluated the impact of cilostazol-based dual antiplatelet treatment on the outcomes. METHODS: Between 2010 and 2015, 137 consecutive patients underwent CAS...
