Carotid plaques with different degrees of carotid stenosis are a common condition in the aged population (10% or more after age 75). If the definition of "symptomatic"carotid stenosis (SCS) indicates association with homolateral neurologic hemispheric lesions and/or retinal deficits even in absence of ischemic changes at CT scan, the overwhelming majority of carotid stenoses can be defined asymptomatic (ACS). Considering the low absolute risk of ipsilateral stroke,the additional risk of myocardial infarction, and the perioperative risk, surgery although beneficial in relative terms, should not be applied indiscriminately but rather in selected cases. There is therefore ample space for medical treatments as reduction of risk factors (especially hypertension), antiplatelet drugs, and statins, both in alternative with, as well as before and after surgery.

CHI3L1 is strongly associated with atherosclerosis, but its role in macrophages remains unknown. In this study, we observed a significant up-regulation of CHI3L1 in both carotid plaques and serum of symptomatic patients, and demonstrated that CHI3L1 impairs the efferocytosis of macrophages by down-regulating crucial efferocytic mediator MFGE8 through inhibiting ATF2, which binds directly to the enhancer of MFGE8. In human plaques, we observed a negative correlation between CHI3L1 expression and both ATF2 and MFGE8 levels, further proved their involvement in plaque destabilization.

Objective: To investigate the short-term blood flow changes and image features of the retina and choroid in patients who underwent carotid artery revascularization (CAR) for severe carotid artery stenosis using widefield swept-source OCT angiography (OCTA).
Design: Prospective study.
Participants: This prospective study included 112 eyes (56 eyes on the ipsilateral side and 56 eyes on the contralateral side) of 56 participants with severe carotid artery stenosis.
Unmasking cerebral infarction: hemianopia and heavy menstrual bleeding in a patient with adenomyosis and vascular abnormalities.

Emergency Department, Shanghai United Family Hospital, 699 Pingtang Road, Changning District, Shanghai, 200335, China.
Background: Adenomyosis, typically associated with heavy menstrual bleeding and pelvic pain, is rarely linked to neurological complications. This case presents a rare instance of ischemic stroke in a young patient with adenomyosis and vascular abnormalities, underscoring the role of anemia, hypercoagulability, and vascular factors as potential contributors to cerebral infarction.
Case Presentation: We describe a 41-year-old female with a history of adenomyosis who presented with right-sided hemianopia and dizziness following severe menstrual bleeding.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

Background: Aortic valve sclerosis (AVS) is a progressive atherosclerotic disease associated with future cardiovascular events (CVE). However, whether its development and prognostic value are independent of arterial atherosclerosis has not been thoroughly investigated. We evaluated the determinants and prognostic value of AVS in conjunction with carotid atherosclerosis.
