Ultra-wide Fluorescein Angiography in Patients With Central Retinal Vein Occlusion Treated by Afilbercept

The pathophysiology of Central Retinal Vein Occlusion (CRVO) is incompletely understood, but a significant slow-down in blood flow, caused by various predisposing factors, results in the release of VEGF, leading to the breakdown of the blood-retinal-barrier and finally to macular edema. The level of VEGF has been also correlated with ...

Phase N/A

CES1 Crossover Trial of Clopidogrel and Ticagrelor

The purpose of this investigation is to evaluate when genetic variation in the carboxylesterase 1 (CES1) gene influences antiplatelet therapy response, as assessed by ex vivo platelet aggregometry, in healthy participants treated with clopidogrel and ticagrelor. We hypothesize that genetic variation in CES1 will significantly impact on-clopidogrel platelet aggregation while ...


A clinical trial to evaluate treatments for patients with Atrial Fibrillation, Thrombosis

Atrial fibrillation is the most frequent heart rhythm disorder. Its symptomatic forms, resistant to drug therapy, require invasive management (catheter ablation), which exposes to potentially serious complications including thromboembolic complications. Despite anticoagulant treatment, intra-atrial thrombus, which is a contraindication to catheter ablation, is detected in nearly 2 % of cases. ...

Phase N/A

Pharmacogenomics of Warfarin in Hispanics and Latinos

If the patient is willing to hear about the study, during routine clinical care, one of the patient's providers will approach patients meeting the study criteria about participation in the study. Study personnel will not approach potential participants unless permission is given to the patient's provider. If the patient would ...

Phase N/A

Study of Elastographic Properties of the Clot by Technical SWIRE (Shear Wave Induced Resonance Elastography)

The main objective of the study is to characterize the in vivo properties of elastographic thrombus in patients with proximal deep vein thrombosis (DVT), for quantitative elastography performed at D0, D7, D30. The ability to analyze the structural properties of the thrombus should allow us to then correlate these properties ...

Safely Ruling Out Deep Vein Thrombosis in Pregnancy With the LEFt Clinical Decision Rule and D-Dimer

VTE is a leading cause of maternal death in the developed world. Suspected DVT in pregnancy is a common clinical problem faced by clinicians daily. The only validated method to exclude DVT in pregnancy requires leg vein CUS imaging. This imaging modality is costly and has limited availability (only available ...

Phase N/A

Warfarin Prevents Portal Vein Thrombosis in Liver Cirrhotic Patients With Hypersplenism After Laparoscopic Splenectomy

After successful screening the cases of cirrhosis of liver irrespective of the etiology who have non tumor portal vein thrombosis will be enrolled. The baseline Doppler parameter will be recorded and the patient will be randomized into either interventional (warfarin) or control (aspirin) group. From postoperative day 3, patients in ...


Searching for Explanations for Cryptogenic Stroke in the Young: Revealing the Etiology Triggers and Outcome

BACKGROUND: In industrialized countries a considerable and increasing proportion of strokes occur at younger ages. Stroke at young age causes marked disability at worst and thus long-standing socioeconomic consequences and exposes survivors for 4-fold risk of premature death compared with background population. Up to 50% of young patients with ischemic ...

Phase N/A

Left Rule D-Dimer Measurement and Complete Ultrasonography to Rule Out Deep Vein Thrombosis During Pregnancy.

In pregnant women with suspected DVT, a sure diagnosis is mandatory. Indeed, false positive tests lead to inappropriate anticoagulant treatment, which increases the risk of bleeding. Conversely, false negative tests might lead to a life-threatening thromboembolic event. Thus, accuracy of diagnostic methods used in pregnant women is crucial [1]. In ...

Phase N/A

PREVENTion of Clot in Orthopaedic Trauma

In this study the efficacy of Low Molecular Weight Heparin (LMWH) (Enoxaparin) compared to Aspirin in the use of preventing death and clinically important blood clots in the lungs in patients who sustain trauma will be investigated. The following comparisons between aspirin and the LMWH are described in the specific ...
