Active clinical trials for "Embolism and Thrombosis"

Remote ischemic postconditioning (RIPC) is suggested to protect the cerebral cell against ischemia in various settings. However, the effect of RIPC in patients with acute ischemic stroke who undergo thrombolysis has yet to be examined. In this single-center, randomized controlled trial, we examined the effect of RIPC on the resolution of nerve function deficient in response to thrombolysis. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after thrombolysis. The primary endpoint was the recovery of nerve function deficient assessed by National Institutes of Health Stroke Scale(NIHSS), Activities of Daily Living(ADL), Modified Rankin Scale(mRS), CT cerebral perfusion imaging (CTP) and CT angiography(CTA). Secondary endpoints included the following: angiogenesis assessed by the level of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF).

This is a compassionate use, proof of concept, phase IIb, prospective, interventional, pilot study in which the investigators will evaluate the effects of compassionate-use treatment with IV tirofiban 25 mcg/kg, associated with acetylsalicylic acid IV, clopidogrel PO and fondaparinux 2.5 mg s/c, in patients affected by severe respiratory failure in Covid-19 associated pneumonia who underwent treatment with continuous positive airway pressure (CPAP).

Thromboembolisms (TEs) in patients with critical COVID-19 has been reported to be three times higher than for other critically ill patients. Immunothrombosis has been proposed as a plausible mechanism for COVID-19 coagulopathy. Corticosteroids improve survival in patients with critical COVID-19, and likely even more so with a higher dose. However, the evidence regarding the impact on the incidence of thromboembolic and bleeding events are currently uncharted. The aim of this study is to investigate if there is a difference in the incidence of thromboembolic events during ICU stay in patients with critical COVID-19 when treated with 12 mg dexamethasone compared to 6 mg dexamethasone.

The purpose of this study is to determine whether TTP889 prevents venous thromboembolism following surgery to repair hip fracture.

The objective of this study is to compare the efficacy, safety of DU-176b 30mg or DU-176b 15mg versus enoxaparin sodium for the prevention of venous thromboembolism in patients after elective total hip arthroplasty.

To determine the benefits and risks of oral anticoagulant therapy in reducing embolic stroke and systemic emboli in patients with atrial fibrillation without rheumatic heart disease.

The purpose of this study is to investigate the preventability of serious adverse drug reactions (ADRs) related to the use of direct oral anticoagulants (DOACs). The investigators also aim at identifying the underlying causes of these preventable ADRs. The endpoint measurements will be compared with a group of patients taking vitamin-K antagonists (VKAs). For this purpose, a protocol for a prospective observational study was developed. The study was approved by the Ethics Committee of the CHU UCL Namur (site Godinne) and the Cliniques Universitaires Saint-Luc. Patients admitted to the emergency department of these two teaching hospitals with a thrombotic or a bleeding event while under DOAC or VKA are included. After a comprehensive medication history, the appropriateness of prescribing is evaluated, using an adapted version of the Medication Appropriateness Index. Causality, severity and preventability of adverse events are assessed by two pharmacists and two hematologists using predefined scales. Second, for cases of serious and preventable ADRs, semi-structured interviews are performed with general practitioners to understand the underlying causes of medication errors. Based on the results, risk-minimization strategies that specifically target the problems encountered in clinical practice will be proposed.
