Asymptomatic mild carotid artery stenosis is relatively frequent and associated with an increased risk of cardiovascular events. Its recognition is clinically relevant for appropriate prevention strategies. These include a healthy lifestyle approach and a careful pharmacologic control of cardiovascular risk factors, such as hypertension, hypercholesterolemia, and diabetes. Furthermore, interventions able to reduce the risk of atherothrombotic events, such as antiplatelet drugs, should be considered. Noninvasive imaging of carotid artery plaque and stenosis severity and morphology may add relevant information for the risk stratification of these subjects.

A hands-free carotid Doppler can identify spontaneous circulation without interrupting cardiopulmonary resuscitation: an animal study.
Intensive Care Med Exp

Faculty of Nursing and Health Sciences, Nord University, Bodø, Norway.
Background: Identifying spontaneous circulation during cardiopulmonary resuscitation (CPR) is challenging. Current methods, which involve intermittent and time-consuming pulse checks, necessitate pauses in chest compressions. This issue is problematic in both in-hospital cardiac arrest and out-of-hospital cardiac arrest situations, where resources for identifying circulation during CPR may be limited.

Background: Neovascularisation of carotid plaques contributes to their vulnerability. Current imaging methods such as contrast-enhanced ultrasound (CEUS) usually lack the required spatial resolution and quantification capability for precise neovessels identification. We aimed at quantifying plaque vascularisation with ultrasound localization microscopy (ULM) and compared the results to histological analysis.

Neurological Surgery, Thomas Jefferson University, Philadelphia, PA, US.
Objective: In recent years, the application of robotic assistance in diagnostic and therapeutic endovascular neurointerventional procedures has gained notable attention. In this systematic review and meta-analysis, we aim to evaluate the feasibility, safety, and current indications of robotic-assisted neurointerventions and to assess the degree of robotic assistance and reasons for unplanned manual conversion from robotic assistance.
Methods: We searched Medline, Scopus, Web of Science, and Cochrane Library databases following PRISMA guidelines and included studies with ≥ 4 patients reporting on robotic-assisted neurointerventions.
Replaced right posterior cerebral artery associated with ipsilateral superior cerebellar artery type persistent trigeminal artery variant diagnosed by magnetic resonance angiography.
Surg Radiol Anat
December 2024
Department of Neurosurgery, Saitama Sekishinkai Hospital, 2-37-20 Irumagawa, Sayama, Saitama, 350-1305, Japan.
Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.
Determining the Optimal Age for Extracranial-Intracranial Bypass Surgery: A Post Hoc Analysis of the CMOSS Randomized Trial.
Stroke
December 2024
Department of Neurosurgery and Interventional Neuroradiology, Xuanwu Hospital, China International Neuroscience Institute, Capital Medical University, National Center for Neurological Disorders, Beijing, China. (L.J.).
Background: Previous trials have failed to demonstrate the benefits of extracranial-intracranial (EC-IC) bypass surgery for patients with carotid or middle cerebral artery occlusion. However, little evidence has focused on the effect of age on prognosis. This study aimed to explore whether EC-IC bypass surgery can provide greater benefits than medical therapy alone in specific age groups.
