Active clinical trials for "Thromboembolism"

The aim of the study is to associate dose of thromboprophylaxis with outcome in critically ill COVID-19 patients. This will be done by associating dose of thromboprophylaxis with 28-day mortality, survival outside ICU, thromboembolic event and bleeding complications.This was done in our earlier study for patients admitted in March and April (Clinicaltrials.gov NCT04412304 June 2 2020) but now we will include the patients admitted in May, June and half of July and we will ad the outcome of 90-day mortality.

Coronavirus disease 2019 (Covid-19) is now a leading cause of death among U.S. adults. In addition to profound respiratory and multi-organ failure, hypercoagulable states and venous thromboembolism (VTE) have been increasingly reported in patients with severe Covid-19. The aim of this study is evaluate the risk of VTE related to Covid-19 infection in a real-world community-based population.

Recent data (Srikanthan and Tran et al. JCO 2014, in press) have demonstrated that the presence of large retroperitoneal lymph node metastases on baseline staging scans (measuring >5cm in axial dimension) are associated with significantly increased risk of venous thromboembolism in patients receiving first line chemotherapy for disseminated germ cell tumours. This study, a G3 collaborative effort, aims to confirm these findings in a large multi-national validation cohort.

This study is to define the optimal method of prophylaxis for patients with gastrectomy in Korea and the investigators hypothesized only mechanical method would be enough for preventing VTE on perioperative period.

The purpose of the study is to use data from a health care information database to assess the risk of venous thromboembolism (blood clots), myocardial infarction (heart attacks), and stroke among women using a transdermal contraceptive system (ORTHO EVRA) for birth control compared with women using norgestimate-containing oral contraceptives with 35 mcg ethinyl estradiol.

The purpose of the study is to evaluate patients with inferior vena cava (IVC)thrombosis in terms of etiology, clinical course and prognosis during long-term follow-up. Patients with isolated lower extremity DVT, matched for age and gender, serve as controls.

The TE Registry is a multi-institutional bioinformatics database for the collection of data relevant to TE. Participating HTRS affiliated study centers may enroll patients and enter data in the TE Registry by completing enrollment and data entry forms and transmitting them to the study center. The purpose of this study is to improve our understanding of the epidemiology, pathophysiology, and outcome of patients suffering from thromboembolism (TE) events. The initial objectives of the registry are: Evaluate the epidemiology and clinical characteristics of known prothrombotic risk factors in persons with TE. Identify the frequency and nature of complications associated with TE and its treatment. Describe the phenotypes and complications seen in persons with multiple molecular risk factors for TE. Compare the epidemiology, clinical characteristics, and complications seen in patients with and without known risk factors for TE.

To perform a randomized clinical trial comparing continuing one month of treatment with heparin in patients with deep venous thrombosis to standard care using heparin for five days and oral warfarin for three months.

The purpose of this study is to determine the current level of adequacy of the thromboprophylaxis prescriptions with the specific institutional protocol during the post-partum period. The institutional protocol is based on national and international guidelines.

The purpose of the study is to assess the frequency of the occurrence of a venous thrombosis in patients with the new Coronavirus disease, who are admitted to the Intensive Care Unit for impending respiratory failure requiring intubation and mechanical ventilation. Furthermore, the investigators aim at identifying potential risk factors for thrombosis and death.
