Active clinical trials for "Embolism"

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).

In this study, 120 patients with Acute Respiratory Distress Syndrome (ARDS) will be included on a two years-period in an intensive care unit (Assistance Publique des Hôpitaux de Marseille, France). Those patients will benefit from a blood test at inclusion in order to measure several coagulation biomarkers, including EV-TF. Subsequently, these patients will be treated according to the usual practices of the department, following recommendations. Patients who received an injected CT scan between Day 5 and Day 28 will be divided into two groups based on the presence or absence of a pulmonary embolism on imaging. The measured values of EV-TF levels and other studied biomarkers will be compared between these two groups in order to detect a possible association between them and the diagnosis of pulmonary embolism. It should be noted that patients receiving an injected CT-scan between Day 5 and Day 7 will be included in the main analysis while those receiving it between Day 8 and Day 28 will be included in the secondary analysis. Others will be excluded from any analysis. At the same time, several collections of clinical data will be carried out: on Day 1, Day 7, Day 28, and on the day of the CT scan if it is performed at another time.

The goal of this exploratory observational study is to assess the feasibility and real-world clinical impact of implementing Artificial Intelligence (AI) software for the detection of acute Pulmonary Embolism (PE) in patients who undergo Computed Tomography Pulmonary Angiogram (CTPA). The main questions that this study aims to answer are: [Question 1] What is the real-world impact of AI on the clinical outcomes and decision making by radiologists and clinicians in the management of acute PE? [Question 2] Is AI software for the detection of acute PE acceptable to use in clinical practice and do they have a favourable impact on clinical workload? [Question 3] Is it cost-effective to implement AI software for the detection of acute PE in clinical practice? Patients having a CTPA for the detection of acute PE will have their imaging analysed by AI software in combination with a human radiologist. Researchers will aim to compare the clinical and radiology specific outcomes with a retrospective cohort of patients who have had standard routine radiology reporting.

The PREVENTER Trial aims to compare the use of perioperative pharmacologic prophylaxis (subcutaneous heparin) with intermittent pneumatic compression devices (IPCs) to the use of IPCs alone for the prevention of venous thromboembolism (VTE) after radical prostatectomy (RP).

REMMITE, a retrospective and prospective registry with one-year follow-up, will provide valuable insights into the clinical diagnosis, management, treatment trends as well as related outcomes of three cohorts: DVT, DVT-PE, PE patients throughout many regions of Mexico and through different health care systems.

The primary objective of this retrospective case review study is to determine the safety and effectiveness of the Penumbra and Indigo Systems for mechanical thrombectomy in a cohort of patients with confirmed peripheral or visceral arterial occlusion or embolus. This is a retrospective, single arm, multi-center trial. Up to 100 patients at up to 10 centers will be enrolled. Angiographic assessment of vessel patency at immediate post-procedure as measured by TIMI scores and procedural serious adverse events are assessed and recorded.

The VICTORIA Study (Vascular CalcIfiCation and sTiffness induced by ORal antIcoAgulation) is a comparative, parallel, prospective, controlled and randomized study of the structural and functional impact of rivaroxaban versus anti-vitamin K drugs on the arterial vasculature.

The study will compare standard catheter directed thrombolysis to ultrasound accelerated thrombolysis for the treatment of acute submassive pulmonary embolism (PE). The study population will include patients eligible for catheter directed thrombolysis (CDT) for submassive PE. Subjects will be randomized to, either, standard catheter-directed thrombolysis or ultrasound-accelerated thrombolysis (USAT).

The purpose of this study is to determine if the EKOS EkoSonic® Endovascular Device when used in conjunction with recombinant tissue plasminogen activator (t-PA) as a treatment for acute PE will decrease the ratio of right ventricle (RV) to left ventricle (LV) diameter within 48 =/- 6 hours in participants with massive or submassive PE.

Comparative trials of urokinase (UK) for 12 hours（UK-12h）or 24 hours (UK-24h) have produced similar results in acute pulmonary thromboembolism (PTE) thrombolysis. It is unclear whether the infusion time can be reduced further. The aim of this study was to investigate the efficacy and safety of weight adjusted dosage of UK-2h (20 000 IU/Kg) regime with the Uk-12h regime in selected patients with PTE in Chinese population.
