We describe the case of a 75-year-old man affected by a chronic obstructive pulmonary disease and chronic renal failure admitted to our emergency department for dyspnea and interscapular stabbing pain. Chest radiography showed diffuse parenchymal consolidation in the lower right lung with bronchiectasis, but the treatment for infection disease did not improve the clinical conditions of the patient. According to Wells score indicating an intermediate risk for pulmonary embolism, we performed a chest ultrasonography that showed ultrasonographic patterns of thromboembolism. Because the presence of chronic renal failure limited the execution of a helical computed tomographic pulmonary angiography, a pulmonary scintigraphy was performed confirming the diagnosis of pulmonary embolism. Our case suggested that chest ultrasonography can be a valuable tool for early detection of pulmonary embolism and to establish immediately an appropriate therapy.

Patients on chronic anticoagulation undergoing metabolic surgery represent an increased risk of complications, including both bleeding and thrombotic events, such as deep vein thrombosis (DVT) and pulmonary embolism (PE). The optimal perioperative management of patients who are receiving chronic anticoagulation therapy (CAT) is complex. In the colorectal surgery literature, patients on CAT have a 10% rate of peri-procedural bleeding and a 3% rate of thromboembolism.

Inferior vena cava (IVC) filters are vital in preventing pulmonary embolism (PE) by trapping large blood clots, especially in patients unsuitable for anticoagulation. In this study, the accuracy of two common simplifying assumptions in numerical studies of IVC filters-the rigid wall assumption and the laminar flow model-is examined, contrasting them with more realistic hyperelastic wall and turbulent flow models. Using fluid-structure interaction (FSI) and computational fluid dynamics (CFD) techniques, the investigation focuses on three hemodynamic parameters: time-averaged wall shear stress (TAWSS), oscillatory shear index (OSI), and relative residence time (RRT).

: Neuroendocrine neoplasms (NENs) are a heterogeneous group of tumors with unique biological characteristics and complications, including thromboembolism. This systematic review evaluates the incidence, types, and clinical outcomes of venous thromboembolic events (VTEs) in NEN patients. : A systematic search of PubMed, Scopus, and Embase was conducted to identify studies on TEs in NENs.

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease characterized by leukopenia and thrombocytopenia, and aspergillosis is a common complication in severe cases. Previous studies have reported cases of SFTS complicated with invasive pulmonary aspergillosis (IPA) and central nervous system aspergillosis. Here, we present the first case of an immunocompetent patient with SFTS who progressed to IPA and Aspergillus endocarditis after glucocorticoid treatment, and embolism of the vegetations from the left ventricle led to multiple infarctions in the brain, kidney, and spleen.

Objective: To explore the application effectiveness of multidisciplinary team (MDT) in the diagnosis and treatment of chronic refractory wounds, and to provide new ideas for optimizing the clinical diagnosis and treatment of such diseases.
Methods: A retrospective analysis was performed on the clinical data of patients with chronic refractory wounds who underwent surgery at Peking University Third Hospital from January 2015 to October 2023, and a total of 456 patients, including 290 males and 166 females, with an average age of (49.4±16.
