Active clinical trials for "Thromboembolism"

Obstructive sleep apnea (OSA) is a clinical syndrome characterized by repetitive closure of the airway and frequent awakenings during sleep. Repeated episodes of hypoxia, decrease in intrathoracic pressure, increased venous return and venous stasis, damage to vascular wall may ensue. An increased tendency for coagulation has also been reported in OSA. Venous stasis, vascular endothelial activation and hypercoagulability are also known risk factors for thromboembolism. All of these pathophysiologic changes in OSA may predispose patients for the development of pulmonary embolism (PE) however there is limited data about role of thromboembolic events in OSA.

This post-marketing surveillance study was designed to collect and assess the information on proper use of fondaparinux injection, such as the safety and efficacy under actual use conditions, in subjects undergoing orthopedic surgery of the lower limb at high risk of developing venous thromboembolism. (ARIXTRA® is a trademark of the GlaxoSmithKline group of companies.)

To compare the efficacy and safety of prophylaxis of venous thromboembolism by Nadroparin during hospitalization to long-term usage in patients with advanced lung cancer treated by chemotherapy and/or radiotherapy.

The objective of this study is to observe the safety, tolerability, and compliance in the use of Fragmin® for prolonged thromboprophylaxis in post-surgery high-risk orthopedic patients.

An observational cohort study on safety and efficacy to generate additional data on the benefit/risk profile of the 150 mg dose of Pradaxa in patients with renal impairment

To evaluate the efficacy of using IPC during the acute phase of ICH in the prevention of VTE. To assess the safety and efficacy of additional therapy with enoxaparin. To compare the efficacy and safety of the European and American guideline recommendations. To provide an efficient and safe thromboprophylaxis for several weeks until the patient is able to walk.

The purpose of this study is to evaluate the impact of thromboembolic diseases and heparin complications in patients with a lower limb trauma supported by physicians of mountain.

RATIONALE: Patients with gliomas may be at risk for developing blood clots. Learning about the risk factors for developing blood clots may help doctors plan better treatment for gliomas. PURPOSE: This clinical trial is studying risk factors for developing blood clots in patients who are undergoing cancer treatment for newly diagnosed gliomas.

RATIONALE: A test that detects abnormal blood clotting in patients with cancer may help doctors plan cancer surgery. PURPOSE: This laboratory study is looking at a new blood test to detect abnormal clotting in patients with metastatic cancer undergoing surgery.

To assess the interaction between hormone replacement therapy and the prothrombotic mutations, Factor V Leiden and the recently described prothrombin mutation (20210A) on the incidence of venous thromboembolism (VTE) in a population-based case-control study conducted at Group Health Cooperative of Puget Sound (GHC).
