Abstract Objective: To investigate the status and influencing factors of central venous catheter-associated thrombosis in children after congenital heart surgery and to provide evidence for preventive measures. Methods: From January 2024 to March 2024, hospitalized children with central venous catheters (CVC) in the Shanghai Grade III Children’s Hospital intensive care unit were selected. Catheter-related thrombosis (CRT) was evaluated using bedside ultrasound technology combined with visible thrombus after CVC extraction, dividing the patients into the thrombus and non-thrombus groups. Univariate and LASSO regression analyses were used to analyze the factors influencing CRT in children after congenital heart More >

Abstract Pulmonary embolism (PE), caused by deep venous thrombosis (DVT), is a disease with high morbidity and mortality. Implantation of inferior vena cava filters is an important method for the clinical prevention of PE. The hemodynamic characteristics of filters implanted in the inferior vena cava (IVC) have a significant impact on their performance. However, IVC diameters vary among patients. This may have a direct impact on the hemodynamic properties of the filter. At present, there is no research on this kind of problem to be investigated. In this paper, the hemodynamic properties of the VenaTech convertible… More > Graphic Abstract

Abstract Introduction: This study examined the clinical accuracy of ultrasonography compared to magnetic resonance imaging (MRI) and intraoperative findings for evaluation of tumor thrombi level in patients with renal cell carcinoma.
Materials and methods: We retrospectively identified 38 patients at our institution who underwent both ultrasonography and MRI before undergoing open radical nephrectomy with tumor thrombectomy between 2010 and 2019. We compared tumor thrombus level findings of both ultrasonography and MRI, as well as the diagnostic accuracy of each to intraoperative findings. Agreement between ultrasonography, MRI, and surgery was tested with kappa. Logistic regression models identified factors that… More >

Abstract Background: Thromboembolic events are a cause of significant morbidity and mortality in the Fontan population. We previously reported on coagulation profile changes in a cohort of patients with hypoplastic left heart syndrome (HLHS) from Stage I through Fontan completion. In this report, we examine their clinical status, anticoagulation and incidence of thromboembolic events up to 20 years post Fontan. Methods: A retrospective chart review was conducted for twenty (20) surviving patients, from 1998 through December 2020. Patients who underwent orthotopic heart transplantation (OTx) were followed until their transplant. Patients who were found in the original study… More >

Abstract Background: Congenital coronary artery fistula (CCAF) is a rare anomaly. Treatment strategies tend to close the defect with a symptomatic and significant shunt, primarily based on expert consensus and case series. Results for long-term follow-up in children are limited Methods: We conducted a retrospective study to assess clinical and imaging outcomes of children with CCAF at Siriraj Hospital, Thailand during 2000–2020. Patients with single ventricle were excluded. Treatment strategies [surgical closure (SC), and percutaneous closure (PC)] were classified and the clinical outcomes at the follow-up in 2021, including coronary thrombosis, myocardial ischemia, and the results of… More > Graphic Abstract

Abstract Introduction: Prolonged operative times have been associated with an increased risk of complications in other major abdominal surgeries. This study tests the hypothesis that longer operative times will be associated with an increased risk of perioperative complications after radical cystectomy (RC).
Materials and methods: Adult patients who underwent RC from January 1, 2012, through December 31, 2016, were identified from the National Surgical Quality Improvement Program (NSQIP) database. A natural log transformation was used to determine cutoff points for operative times at the 33rd, 67th, and 90th percentiles: 272, 371, and 479 minutes, respectively. Cohorts were divided… More >

Abstract Platelet aggregation plays a central role in pathological thrombosis, preventing healthy physiological blood flow within the circulatory system. For decades, it was believed that platelet aggregation was primarily driven by soluble agonists such as thrombin, adenosine diphosphate and thromboxane A2. However, recent experimental findings have unveiled an intriguing but complementary biomechanical mechanism—the shear rate gradients generated from flow disturbance occurring at sites of blood vessel narrowing, otherwise known as stenosis, may rapidly trigger platelet recruitment and subsequent aggregation. In our Nature Materials 2019 paper [1], we employed microfluidic devices which incorporated micro-scale stenoses to elucidate the… More >

Abstract In order to improve the surgical treatment of the congenital heart disease patient with single ventricle defect, two axial flow blood pumps, one with diffuser and the other without diffuser, were designed and virtually implanted into an idealized total cavopulmonary connection (TCPC) model to form two types of Pump-TCPC physiological structure. Computational fluid dynamics (CFD) simulations were performed to analyze the variations of the hemodynamic characteristics, such as flow field, wall shear stress (WSS), oscillatory shear index (OSI), relative residence time (RRT), between the two Pump-TCPC models. Numerical results indicate that the Pump-TCPC with diffuser More >

Abstract Thrombotic diseases where platelets form clots and obstruct blood vessels remains the leading cause of death and disability in the world. Despite intense investigation over the last 40 years into the discovery and development of more effective drugs, less than 1 in 6 patients taking anti-thrombotic therapies avoid a fatal event. This situation is likely to worsen in younger generations due to the rapidly growing incidence of diabetes, which makes people more prone to thrombosis and resistant to existing anti-thrombotics with unknown reasons.
To investigate this, I have developed the ‘Biomembrane Force Probe’ as the… More >

Abstract Objective: Thoracic endovascular aortic repair (TEVAR) of type B aortic dissection (AD) is to initiate the thrombosis in the false lumen to eventually result in aortic remodeling. We aim to find out whether the false lumen (FL) thrombosis rate after TEVAR can be predicted accurately by an index that expresses the degree of aortic arch angulation. Method: Three-dimensional aortic arch geometry of 39 type B AD patients (mean age: 48 years) after TEVR were reconstructed from post-operative CT images. For the first time, the question mark which takes into account the curvature of both aortic arch… More >
