Small subcortical ischemic infarction and other DWI lesions establish predictive model for MES.
Front Neurol
January 2025
Department of Neurosurgery, Affiliated Hospital of Shandong Second Medical University, Weifang, China.
Objective: The relationship between small subcortical ischemic infarction remains poorly characterized. Therefore, the present study aimed to investigate the association between artery-to-artery embolization and small subcortical infarctions.
Methods: This retrospective observational cross-sectional study enrolling 230 patients with acute middle cerebral artery (MCA) stroke classified into the microembolic signals-positive (MES+) and MES-negative (MES-) groups.
Newly developed DWI hyperintensities and changes in cerebral blood flow after carotid stent placement for unilateral symptomatic carotid artery stenosis.
Medicine (Baltimore)
January 2025
Department of Neurology, Haiyan People's Hospital Jiaxing, Zhejiang, China.
This study aimed to evaluate changes in cerebral blood flow and perioperative outcomes in patients with unilateral symptomatic carotid artery stenosis before and after carotid artery stenting (CAS), providing insights to guide surgical decision-making. Ninety-six patients with moderate to severe unilateral symptomatic carotid artery stenosis (>50%) admitted to the Neurology Department of the Second Affiliated Hospital of Zhejiang University from June 2023 to April 2024 were included. All patients underwent CAS and magnetic resonance imaging, including diffusion-weighted imaging (DWI) and 3D quasi-continuous arterial spin-labeled perfusion imaging, within 3 days preoperatively and on the third postoperative day.

Medicina (Kaunas)

Department of Cardiac Surgery, Anthea Hospital GVM Care and Research, Via Camillo Rosalba 35/37, 70124 Bari, Italy.
In coronary artery bypass grafting (CABG) on pump, achieving optimal visualization is critical for surgical precision and safety. The use of blowers to clear the CABG anastomosis poses risks, including the formation of micro-embolic gas bubbles, which can be insidious and increase the risk of cerebral or myocardial complications. This retrospective study compares the effectiveness of the use of irrigation mist and CO versus a direct CO blower without irrigation in terms of visualization, postoperative fibrillation, and micro-embolic gas activity.

Front Rehabil Sci
December 2024
Nursing Department, Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, Hangzhou, Zhejiang, China.
Article Synopsis
- Postoperative cognitive dysfunction (POCD) is a common issue in elderly patients after cardiac surgery, primarily influenced by factors like age and preoperative cognitive levels.
- Causes of POCD include cerebral microembolism, neuroinflammation, and strokes that may not have clear origins.
- Effective rehabilitation strategies—such as cognitive training, exercise, acupuncture, and new technologies like virtual reality—are vital for improving cognitive outcomes in these patients.
Microembolic signal detection in acute ischemic stroke: Clinical relevance and impact on treatment individualization-A narrative review.
Eur J Neurol
January 2025
Second Department of Neurology, School of Medicine, "Attikon" University Hospital, National and Kapodistrian University of Athens, Athens, Greece.
Background: Microembolic signals (MES) can be detected using transcranial Doppler (TCD) ultrasound in several clinical scenarios, including acute ischemic stroke (AIS). This narrative review aims to provide insights into their role in AIS patient management and outcomes.
Methods: The present narrative review consolidates current observational and randomized evidence on the prevalence and clinical relevance of MES in different AIS subtypes and settings.
