Filter by:This study evaluates the risks and experience of blood clots and bleeding in patients with blood cancers. While it is standard of care to use medications to reduce the risk of blood clots in hospitalized individuals, some patients with blood cancers have low platelet counts that can increase the concern for bleeding complications associated with these medications. At this time, the optimal management strategies for blood clots are not well known for patients with blood cancers. This pilot study evaluates additional information that could help doctors know which patients are at highest risk for blood clots.
Inclusion (J0): - Information - Verification of inclusion and non-inclusion criteria - Collection of consent - MRI examination with injection of contrast product as part of the treatment comprising the sequences: T1 TFE 1.0 iso 3D FLAIR injected Injected elliptical venous angiography 0.4mm iso or less 3D SWIp multiecho 3D T1 injected FABIR iso without injection (added as part of care in case of suspected ASH or meningitis) FLAIR 1.0 without injection (added as part of care for suspected ASH or meningitis) T2 BFFE XD (added by search) FABIR iso injected (added by research) 3D PD T1 0.55 MSDE iso injected (added by research) Clinical information (SRM on inclusion, on discharge and at 3 months and recurrence within the year) will be collected from the patient's medical file
The NoCVT study will investigate CVT (2014-2023) in a large Norwegian population (> 3 millions) using several approaches combining existing health registries, clinical databases and new prospectively collected clinical data to explore epidemiology, risk factors, diagnostics, treatment, and the long-term prognosis of CVT.
The objective of this study is to demonstrate the safety and efficacy of the Indigo Aspiration system for percutaneous mechanical thrombectomy in a population presenting with obstruction due to deep vein thrombosis (DVT) who are eligible for treatment.
This is a pragmatic, multi-center, prospective, observational, non-interventional study and standing database of patients hospitalized for transient ischemic attack (TIA) or stroke in the 11 accredited adult neurology training institutions in the Philippines. Data will be collected from each patient while admitted in the hospital and until hospital discharge. Data collection for this study will span 3 years from study initiation, after which the utility of an extension or a re-implementation of the study will be assessed.
The efficacy and safety of anticoagulant treatment is not established for patients with acute symptomatic isolated distal deep vein thrombosis (IDDVT). The latest Antithrombotic Therapy for VTE Disease Guideline suggested using the same anticoagulation as for patients with acute proximal DVT in patients with acute IDDVT. However, a single-center retrospective cohort study found therapeutic anticoagulation was associated with an increase risk of bleeding. Thus, this study aimed to assess the short-term risk of recurrent venous thrombotic events and bleeding events in patients with a first acute symptomatic IDDVT of the leg treated with prophylactic or therapeutic anticoagulant therapy with rivaroxaban.
The goal of the CRETE Studies is to investigate the newly identified age-dependent heterogeneity in the efficacy of enoxaparin in reducing the risk of central venous catheter-associated deep venous thrombosis in critically ill children.
Compression ultrasound is commonly used in emergency department. Accuracy to rule out deep vein thrombosis is excellent but lower then Ddimer assessment which is actually gold standard. With progress in formation of emergency physicians (EP), quality of material used, the investigators hypothesize that compression ultrasound can rule out deep vein thrombosis in case of non high probability, as standard care and DDimer assay.
If deep vein thrombosis (DVT) is suspected among patients who have symptoms such as pain or swelling of the lower extremities, duplex ultrasound of the lower limb is the first-line imaging modality to diagnose DVT. However, duplex ultrasound is time consuming, requires patient transport to a diagnostic imaging facility. In recent years, abbereviated bedside ultrasound technique has been accepted by emergency physician to diagnose the presence of DVT. Several studies have proven that the accuracy of this abbreviated bedsude ultrasound for assessing the presence of deep vein thrombosis is not inferior to experts, but how much ultrasound experience is required to obtain the accuracy that does not inferior to experts has yet to be studied. The aim of this study is to identify how much learning by emergency physicians is needed to obtain the accuracy of the lower extremity ultrasound examination comparable to that of experts.
In the context of anti-Covid19 vaccination, atypical thrombosis have occured and potential link with vaccination is under investigation. This study collect clinical and biological data of all atypical thrombosis occurring within 4 weeks after antiCovid vaccination.
