Active clinical trials for "Thrombosis"

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common post-operative complication. The necessity for anticoagulant therapy after orthopedic surgeries is widely understood, but treatment administration patterns in the prevention of venous thromboembolism (VTE) after orthopedic surgeries during the hospital stay have yet to be examined. The main objective of this study is to perform a comparative effectiveness review examining the benefits and harms associated with venous thromboembolism prophylaxis in patients undergoing orthopedic surgeries. It is around efficacy and safety evaluation of using anticoagulant for thromboprophylaxis in patients undergoing orthopedic surgeries taking into the account the reliable selection of patients most benefit. The aims of this study is to analyze patient records in teaching hospitals database of our country (including: Hanoi Medical University, Bach Mai Hospital, Cho Ray Hospital, Viet Duc University Hospital) and compare the outcomes and costs between different types of anticoagulant medications that were prescribed for the prevention of VTE following orthopedic surgeries. This analysis will assess and quantify the outcomes, resource utilization, and cost of care for patients receiving rivaroxaban or enoxaparin. The outcomes of interest include the occurence of DVT and PE, rates of major bleeds, medical resource utilization, and total costs (medical plus pharmacy).

This is a post-market, observational, retrospective multi-center Registry designed to gather information on the performance of the Angel® Catheter in general clinical practice.

This study aims to compare the results of two mini invasive surgical approaches in abdominal aortic surgery: mini lumbotomy with retroperitoneal approach versus mini laparotomy with transperitoneal approach. Respiratory and renal functions and recovery of intestinal transit will be assessed after 30 days. The secondary purpose of this study is to assess the life quality and morbi-mortality at 30 days, as well as at 6 and 12 months.

Coronavirus disease-2019 (COVID-19), a viral respiratory illness caused by the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has been associated with the occurrence of cardiovascular adverse events including acute myocardial injury, acute heart failure, cardiac arrhythmias, and thromboembolic disease. These complications represent an important issue in COVID-19 patients accounting for the increased morbidity and mortality of this syndrome. According to a scoping review, venous thromboembolism and stroke occurred in approximately 20% and 3% of patients, respectively, with higher frequency observed in severely ill patients admitted to intensive care units. Despite the use of pharmacological thromboprophylaxis, the thrombotic risk still remained elevated in severe COVID-19 patients, and the optimal doses and timing of anticoagulation are not yet defined. The pathogenesis of COVID-19 associated thrombosis recognizes a prominent role of endothelial damage induced by both direct viral injury and an excessive and aberrant hyper-inflammatory host immune response associated to an increase in infection-related cytokines and chemokines. The occurrence of a hypercoagulable state in COVID-19 patients associated to a profound endothelial cell activation/dysfunction can result in the pathological phenomenon of immunothrombosis. In this study, in a prospective cohort of consecutive COVID-19 hospitalized patients, an extensive characterization of the hemostatic alterations were performed, in order to: 1) clarify mechanisms underlying the coagulopathy in these patients; 2) how and to what extent the concomitant infection with SARS-CoV-2 affect this coagulopathy; and 3) identify biomarkers potentially predictive of disease outcome (i.e. any thrombotic recurrence and death).

PICC related venous thrombosis (PICC-RVT) is one of the common complications of PICC and the main cause of unplanned extubation. Effectively identifying the risk of PICC-RVT in patients and preventing PICC-RVT are of great clinical significance. There are many studies on the risk factors of VTE at home and abroad, and there are also many studies on the risk assessment of PICC catheter-related thrombosis, mostly focusing on sociodemographic data, comorbidities, and intubation related factors, while the research on laboratory related indicators is limited It involves D-dimer, white blood cell count (WBC), platelet count (PLT), etc., but its specificity or positive predictive value is not high, and there is no reliable biomarker report. Studies have shown that the decrease or lack of AT-Ⅲ, PC, PS activity is one of the mechanisms of hypercoagulable state in patients with cancer, and may be a biomarker of thrombosis. Many retrospective studies have also shown that the activities of AT-Ⅲ, PC, and PS are related to the occurrence and recurrence of VTE and DVT. The pathogenesis is mainly anticoagulant protein defect or decreased expression. However, when PICC is implanted in patients with AT-Ⅲ, PC and PS activity defects, whether PICC indwelling will become a predisposing factor of thrombosis is not yet known. Therefore, the purpose of this study is to understand the rate of anticoagulant protein deficiency in patients with tumor PICC-RVT, and to prospectively explore the correlation between the lack of AT-Ⅲ, PC, and PS activities and PICC-RVT, and to provide targeted preventive interventions for PICC-RVT patients Scientific basis.

The main objective of this single arm study is to evaluate the safety and feasibility of the AXS Infinity LS (Stryker, Freemont, CA, USA) and AXS Infinity LS Plus (Stryker, Freemont, CA, USA) catheters during the transradial approach through a secondary use of the data collected during neurointerventional procedures. This includes evaluating the conversion rates to a transfemoral approach. A secondary aim of the study is to assess the radial artery occlusion rates post procedure.

Deep vein thrombosis (DVT) is a common complication of surgery, which could result in pulmonary embolism (PE). PE is a serious and potentially life-threatening syndrome. The purpose of this study is to investigate the impact of laparoscopic versus open surgeries on the incidence of postoperative DVT in patients with gastrointestinal malignancy

This is a large prospective registry of patients submitted to cardiac electronic devices implantation designed to investigate the incidence, risk factors and prognostic of thromboembolic complications associated with transvenous lead implantation.

The FReIburger STent Registry (FRIST) is designed to determine the long term safety and efficacy of Drug Eluting Stents (DES) in a "real-world" patient population requiring stent implantation. FRIST included patients treated with DES and bare-metal stents (BMS) in the University Hospital of Freiburg, Germany, according to a non-restrictive inclusion criterion, in which virtually all consecutive patient subsets were considered eligible.

Heart bypass surgery, also known as coronary artery bypass graft (CABG) surgery, creates a detour around the blocked part of a heart artery to restore blood supply to the heart muscle. The saphenous vein, located along the inside of the leg, is commonly used to create the bypass in a CABG surgery. An abnormal increase in the blood clotting protein thrombin may cause the saphenous vein graft to close up and eventually fail. This study will evaluate the relationship between thrombin levels and saphenous vein graft failures in people undergoing a CABG procedure.
