Active clinical trials for "Embolism"

In France, venous thromboembolic (VTE) disease is usually managed by vascular medicine physicians (VMP). The national OPTIMEV study, conducted more than 12 years ago among VMP practicing in hospital and in the community described the management of VTE in routine clinical practice. Since then a large number of practice changing studies have been published. This includes trials that have validated the use of direct oral anticoagulants (DOAC), the new standard of care of VTE, as per new national and international guidelines. Management of VTE in 2019 appears to be significantly different from the one that prevailed more than 10 years ago when the last national survey was conducted. It is therefore important to have an update on the routine clinical practice management of VTE by VMP. In this perspective the investigators aim to conduct a national survey among VMP practicing in France

IVUS Evaluation of the Bioabsorbable Sentry IVC Filter 3-5 Years Post Deployment Follow up

To asses regional RV function in patients presented with acute pulmonary embolism using speckle tracking echocardiography To evaluate its relationship to long term mortality.

There is increasing evidence that renal replacement therapy (= continuous veno-venous hemodialysis) generates cerebral microembolism which is detectable on transcranial Doppler ultrasound. The aim of this study is to monitor patients with transcranial Doppler under two conditions: during hemodialysis and in a hemodialysis-free interval (in each period cerebral embolic load is detected during 30 minutes). The study hypothesis is that during hemodialysis the cerebral embolic load is significantly higher than in the hemodialysis-free interval.

This is local prospective multicenter observational non-interventional local study. Primary study objective is investigate and describe prescription pattern of neurologists in secondary stroke or non-CNS (non-Central Nervous System) systemic embolism prevention in patients with AF (Atrial fibrillation) and prior stroke or TIA (Transient Ischemic attack) who treat with rivaroxaban at an initial visit and three follow-up visits.

RAZIONALE Pulmonary embolism is a complex disease, with a highly variable clincal presentation. Diagnosis starts with clinical probability assessment mainly based on medical history and rapidly available clinical data. Pulmonary embolism can be managed by emergency department, cardiology, pneumology geriatrics or internal medicine physicians. Thus, initial clinical management can varies based on the attitude of the attending physician. Diagnosis is a crucial point as it can influence short term mortality. OBJECTIVE The registry has 3 main objectives: educational objective, improvement in the knowledge of epidemiology, management and outcome of acute pulmonary embolism in Italy scientific objective

The protocol is a large registry to describe acute, sub-acute and extended duration of anticoagulation management, clinical and economic duration of anticoagulation management, clinical and economic outcomes in patients with treated acute VTE (DVT and PE) in the real-world setting. Main objectives are to clarify the: treatment related details for acute VTE (either conventional anticoagulation therapy, treatment with a direct oral anti-coagulant or other modalities of treatment) Rate of early and late symptomatic VTE recurrence Rate and nature of complications of VTE including post thrombotic syndrome and chronic thromboembolic pulmonary hypertension Rate of bleeding complications Rate of all-cause mortality at six months

A significant number of patients experience postoperative cognitive changes following total joint arthroplasty. Among other causes, the mental status change may be the result of fat and bone marrow debris embolization. We hypothesized that the use of computer assisted total knee arthroplasty, which does not utilize intramedullary alignment rods, would produce less fat and bone marrow debris embolization and, hence, fewer mental status changes.

Pulmonary embolism is associated with a small but definite risk of paradoxical embolism in patients with a patent foramen ovale (PFO). While neurologic complications are unfrequent the incidence of clinically silent brain infarction is unknown. We will assess the rate of clinically apparent and silent cerebral embolism in patients with a pulmonary embolism (PE) in relation to the presence or not of a PFO.

The purpose of this study is to test the hypothesis that using three different techniques to anastomose coronary grafts to the aorta: partial occlusion, single cross clamp, or using the Heartstring anastomotic device, will change the amount of gas and solid microemboli as detected by the EmbodopR transcranial Doppler (TCD) system and consequently the neurocognitive performance of patients after coronary bypass operation.
