Antiplatelet Agents in Endovascular Neurointerventional Procedures.

Minimally invasive, image-guided endovascular procedures are becoming increasingly prevalent as techniques and technologies have advanced, particularly within the realm of neurovascular interventions. Endovascular approaches ubiquitously result in endothelial injury with subsequent risk of thromboembolic complications. Periprocedural antiplatelet agent use is an integral component of the management of patients undergoing endovascular neurointerventional procedures.

Examination of Postoperative Changes in Lipid Profile and Glycemic Markers After Coronary Artery Bypass Graft, Percutaneous Intervention Vs Aortic Valve Replacement Demonstrated a Shift in Risk Factors for Coronary Artery Disease.

Purpose: Surgery-related stress may affect the metabolome, leading to abnormal lipid profiles and ineffective glycemic control. Here, we gauge these changes as they may accelerate atherosclerosis, limiting the benefits of interventions aimed at improving coronary artery disease (CAD) progression.

Patients And Methods: Electronic medical records were queried to identify patients undergoing coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or aortic valve replacement (AVR).

Imaging biomarkers of vascular and axonal injury are spatially distinct in chronic traumatic brain injury.

Traumatic Brain Injury (TBI) is associated with both diffuse axonal injury (DAI) and diffuse vascular injury (DVI), which result from inertial shearing forces. These terms are often used interchangeably, but the spatial relationships between DAI and DVI have not been carefully studied. Multimodal magnetic resonance imaging (MRI) can help distinguish these injury mechanisms: diffusion tensor imaging (DTI) provides information about axonal integrity, while arterial spin labeling (ASL) can be used to measure cerebral blood flow (CBF), and the reactivity of the Blood Oxygen Level Dependent (BOLD) signal to a hypercapnia challenge reflects cerebrovascular reactivity (CVR).
