Filter by:Following the implementation of SPECT V/Q imaging for PE diagnosis, the investigators previously conducted an observational study over the period 2011-2013 that showed the safety of a diagnostic management based on SPECT V/Q to rule out PE. However, PE prevalence was high (28%), which may seem a bit high as compared with other recent studies. The hypothesis was that the use of SPECT V/Q may be responsible for an overdiagnosis of PE, especially at the implementation phase of the test. The aim of this study was to perform a time trend analysis of the evolution over the years of PE diagnosis with SPECT V/Q.
Acute pulmonary embolism is a potentially life-threatening disease with short-term mortality ranges from less than 1% to more than 30% during the hospital stay. Recent guidelines recommend to tailor diagnosis hospitalization and acute treatment based on the estimated risk for short-term Death. The assessment of the contemporary clinical management of patients with acute pulmonary embolism across different specialties would be of crucial value.
To evaluate the impact of an integrated electronic clinical decision support system to facilitate risk stratification and site-of-care decision-making for patients with acute pulmonary embolism.
A study based on a chart review of participants that presented with a sudden blood clot in the lung
Evaluating the safety and outcomes of catheter directed thrombolysis following catheter fragmentation in acute high risk pulmonary embolism
To determine whether peripheral low dose systemic thrombolysis (PLST) is non-inferior to catheter directed acoustic pulse thrombolysis (ACDT) in improving RV function and reducing pulmonary artery pressures in submassive pulmonary embolism (PE)
- Pulmonary embolism (PE) is a diagnostic and therapeutic challenge. The risk of death of untreated PE is approximately 25%. On the other hand, anticoagulant treatment is associated with a haemorrhagic risk (2% of major haemorrhagic accidents per year, of which 10% are fatal). A diagnostic accuracy is therefore necessary. - Two approaches are available to diagnose PE: 1. A functional approach, represented by pulmonary ventilation / perfusion scintigraphy (V / P), which looks for the functional consequences of PE. The main disadvantage of this approach is that there is a high rate of non-diagnostic examinations. On the other hand, it allows a mapping of pulmonary perfusion at the microcapillary scale, and thus allows the quantification of the vascular obstruction index, which would be an independent risk factor of PE recurrence. 2. A morphological approach, represented by CT pulmonary angiography (CTPA), which allows the visualisation of the clot itself. This approach is currently the most used but has some limitations, including a risk of over-diagnosis of pulmonary embolism and the inability to reliably quantify the index of vascular obstruction. Lung subtraction iodine mapping CT is a new technique allowing, during the realization of a CTPA, without additional irradiation, to provide a mapping of the iodine. This mapping of iodine could potentially be used to evaluate pulmonary perfusion. It would then be possible to obtain, during a single examination, in addition to the anatomical information of the thoracic angioscan, information on the pulmonary perfusion and thus to assess the functional consequences of PE. No study to date has evaluated the performance of the pulmonary subtraction CT for the evaluation of pulmonary perfusion in the context of acute pulmonary embolism suspicion.
This study will examine the effectiveness of pre-recorded instructional videos in the use of bedside ultrasonography to ascertain the presence of a lower extremity deep venous thrombosis (DVT) as compared to in-person lectures and hands-on training.
At most institutions, the average patient with clinical concern for PE(pulmonary embolism) will have a CT angiogram(CTA) with contrast of the lungs performed to evaluate for a clot. However, CTA has risks including contrast- induced allergic reactions and nephropathy, as well as radiation which has been linked to development of cancer later in life. There is literature that has looked at using lower extremity doppler ultrasound first to evaluate for a DVT (deep venous thrombosis) in patients where there is concern for a PE. There is also literature showing that emergency medicine physicians can perform adequate lower extremity compression ultrasounds (LCUS), at the bedside with results similar to that of the ultrasound tech. The goal of this project is to fuse both principles by having emergency medicine physicians perform LCUS at the bedside, to help reduce CTA utilization in the evaluation of PE.
The purpose of this study is to evaluate the prevalence rate of pulmonary embolism among not anticoagulated patient older than 75 years old admitted with syncope and hospitalised in the Toulon Hospital
