Evaluation of in-stent restenosis after carotid artery stenting with superb microvascular imaging: initial findings.
Acta Radiol
January 2025
Department of Radiology, Interventional Radiology, Sağlık Bilimleri Üniversitesi Ankara Dışkapı Yıldırım Beyazıt Eğitim ve Araştırma Hastanesi, Ankara, Türkiye.
Background: Carotid artery stenting (CAS) is an interventional management in preventing ischemic stroke caused by carotid artery stenosis. After the treatment with CAS, in-stent restenosis caused by neointimal hyperplasia may develop.
Purpose: This study aims to obtain a better determination of neointimal hyperplasia using superb microvascular imaging (SMI), which provides a high-quality visualization of the endoluminal lesions, and to compare these results with B-mode and Doppler ultrasound (US).
An increase in flow-diverter oversizing values as an independent risk factor for developing more severe in-stent stenosis. A retrospective single-center study based on flow diversion of supraclinoid internal carotid artery aneurysms.

Introduction: In the past decade, flow diverters (FDs) have increasingly been used to treat cerebral aneurysms with unfavorable morphology in which other endovascular techniques fall short of being as effective. In-stent stenosis (ISS) is one of the most puzzling and frequent risks of flow diversion therapy observed on follow-ups. This complication, although mostly placid in its clinical course, can have dire consequences if patients become symptomatic.

Department of Neurosurgery, Shaoxing People's Hospital, Shaoxing, China.
Objective: Endovascular mechanical thrombectomy (EVMT) is widely employed in patients with acute intracranial carotid artery occlusion (AIICAO). This study aimed to predict the outcomes of EVMT following AIICAO by utilizing anatomic classification of the circle of Willis and its relative position to the thrombus.
Methods: In this study, we retrospectively analyzed a cohort of 108 patients with AIICAO who underwent endovascular mechanical thrombectomy (EVMT) at Shaoxing People's Hospital.
Association between Metrnl and carotid atherosclerosis in patients with type 2 diabetes mellitus.
Front Endocrinol (Lausanne)

Department of Endocrine, The 900th Hospital of Joint Logistic Support Force, the Chinese People's Liberation Army (PLA), Fuzhou, China.
Objective: Type 2 diabetes mellitus (T2DM) is a major cause of atherosclerosis, as well as an independent risk factor of cardiovascular adverse events. We aimed to evaluate the association of serum Meteorin-like protein (Metrnl) level with carotid atherosclerosis as determined by carotid intima-media thickness (CIMT) status in subjects with T2DM.
Methods: This cross-sectional study included 83 T2DM subjects without pre-existing cardiovascular diseases.
Proximal protection devices for carotid artery stenting - A benchtop assessment of flow reversal performance.
AJNR Am J Neuroradiol

From the Department of Radiology (J.L., E.A.B., C.B., J.C., R.K., W.B., D.F.K), and Department of Neurologic Surgery (Y.C.S., R.K., W.B.), Mayo Clinic, Rochester, MN, United States; Department of Stroke Research (J.L.), Vall d'Hebron Research Institute, Barcelona, Spain; From the Global Institute of Future Technology (Y.L.), Shanghai Jiao Tong University, Shanghai, China; Department of Neurointerventional Radiology (J.C.), Bicetre University Hospital, Le Kremlin Bicetre, France.
Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.
