During percutaneous coronary intervention for acute myocardial infarction, distal embolization of thrombus and plaque material often occurs, despite the use of thrombectomy and aspiration catheters. Large embolized thrombi can cause occlusion of distal coronary vessels for which angioplasty most often leads to no more than poor results. We describe the successful use of an aspiration catheter to treat distally embolized thrombus, to optimize coronary reperfusion therapy, and to improve salvage of myocardial tissue. We discuss the manifestation and incidence of distal embolization and show its clinical relevance.

Objective: To determine the incidence of clinical and subclinical venous thromboembolic events (VTE) in patients with locally advanced cervical cancer (LACC) treated with high-dose thromboprophylaxis during definitive chemoradiation and brachytherapy.
Methods: A prospective observational study was undertaken from August 2021 to December 2023 in patients with primary LACC treated with definitive chemoradiation in two Dutch tertiary hospitals. Patients received high-dose thromboprophylaxis during chemoradiation and brachytherapy.

Neutrophils are peripheral blood-circulating leukocytes that play a pivotal role in host defense against bacterial pathogens which upon activation, they release web-like chromatin structures called neutrophil extracellular traps (NETs). Here, we analyzed and compared the importance of myeloid differentiation factor 88 (MYD88), peptidyl arginine deiminase 4 (PAD4), and gasdermin D (GSDMD) for NET formation in vivo following sepsis and neutrophilia challenge. Injection of lipopolysaccharide (LPS)/E.

To prevent future ischemic strokes, especially in younger individuals, it is crucial to detect and treat direct and indirect cardioembolic sources.

Catheter-related thrombosis (CRT) is a frequent and potentially serious complication associated with the widespread use of intravascular devices such as central venous catheters, including peripherally inserted central catheters and implantable port systems, pacemakers or implantable cardioverter-defibrillators. Although CRT management has been informed by guidelines extrapolated from lower extremity deep vein thrombosis (DVT), unique challenges remain due to the distinct anatomical, pathophysiological, and clinical characteristics of upper extremity DVT. Risk factors for CRT are multifactorial, encompassing patient-related characteristics such as cancer, prior venous thromboembolism, and infection, as well as catheter-specific factors like device type, lumens, and insertion site.
