RATIONALE AND OBJECTIVES: Pulmonary embolism (PE) is a common condition associated with significant morbidity and mortality. Diagnostic test characteristics reported in terms of sensitivity and specificity are difficult to translate at the clinical level. More relevant measures are likelihood ratios (LRs), which can convert a pretest into a posttest probability. The aim of our study was to calculate the LRs and posttest probabilities for multiple-level test result for ventilation/perfusion (V/Q) lung scintigraphy and for perfusion scintigraphy combined with chest radiography using modified Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) II and the Prospective Investigative Study of Pulmonary Embolism Diagnosis (PISAPED) criteria for each clinical probability level for the most commonly used clinical prediction rules (CPR) using the PIOPED data...

Women are at increased risk of venous thromboembolism (VTE) during pregnancy and VTE remains one of the main causes of maternal mortality in developed countries (Konstantinides SV, et al. Eur Heart J 2014; 35(43):3033-69, 69a-69k). Although an accurate diagnosis of acute pulmonary embolism (PE) in pregnant patients is thus of crucial importance, the diagnostic management of suspected PE is challenging for this specific patient category. As D-dimer levels increase physiologically throughout pregnancy, the optimal D-dimer threshold to rule out PE during pregnancy remains unknown...

The In-hospital Mortality for PulmonAry embolism using Claims daTa (IMPACT) rule can accurately identify pulmonary embolism (PE) patients at low risk of early complications using claims data. We sought to externally validate the IMPACT and simplified Pulmonary Embolism Severity Index (sPESI) tools for predicting all-cause mortality and readmission. We used Veteran Health Administration data (10/1/2010-9/30/2015) to identify adults with ≥1 inpatient diagnosis code for acute PE, ≥12 months continuous medical and pharmacy benefits prior to the index PE, ≥90 days of post-event follow-up (unless death occurred) and ≥1 claim for an anticoagulant during the index PE stay...

INTRODUCTION: Patients presenting to emergency departments (EDs) with suspected pulmonary embolism (PE) can be risk stratified and those who are deemed to be at low risk for PE usually undergo D-dimer testing. A negative D-dimer in this low-risk group rules out PE with a high degree of certainty because of its high sensitivity. The D-dimer is, however, a poorly specific test and positive results often lead to unnecessary radiological imaging (notably computed tomography pulmonary angiography)...

OBJECTIVE: Lung and venous ultrasound are bedside diagnostic tools increasingly used in the early diagnostic approach of suspected pulmonary embolism (PE). However, the possibility of improving the conventional prediction rule for PE by integrating ultrasound has never been investigated. METHODS: We performed lung and venous ultrasound in consecutive patients suspected of PE in four emergency departments. Conventional Wells score (Ws) was adjudicated by the attending physician, and ultrasound was performed by one of 20 investigators...

Background The prevalence of pulmonary embolism among patients hospitalized for syncope is not well documented, and current guidelines pay little attention to a diagnostic workup for pulmonary embolism in these patients. Methods We performed a systematic workup for pulmonary embolism in patients admitted to 11 hospitals in Italy for a first episode of syncope, regardless of whether there were alternative explanations for the syncope. The diagnosis of pulmonary embolism was ruled out in patients who had a low pretest clinical probability, which was defined according to the Wells score, in combination with a negative d-dimer assay...

BACKGROUND: Point-of-care ultrasonography (POCUS) is a widely used tool in emergency and critical care settings, useful in the decision-making process as well as in interventional guidance. While having an impressive diagnostic accuracy in the hands of highly skilled operators, inexperienced practitioners must be aware of some common misinterpretations that may lead to wrong decisions at the bedside. OBJECTIVES: This article provides a revision list of common POCUS misdiagnoses usually found in practice and offers useful tips to recognize and avoid them...

During the past 7 years, results from phase III trials comparing nonvitamin antagonist K oral anticoagulants (NOACs) with vitamin K antagonists (VKAs) or with placebo, including 34,900 patients, have been published. Recent guidelines have been updated and now suggest treatment with NOACs rather than with VKA. Other updates in the guidelines concern the initial thrombolytic treatment for selected patients with deep vein thrombosis or pulmonary embolism as well as the possibility of withholding anticoagulation for minimal venous thromboembolism...

BACKGROUND: Acute pulmonary embolism (PE) is associated with a variety of non-specific clinical manifestations. Using diagnostic algorithms that are based on internationally recognized guidelines, pulmonary computed tomography angiography (CTA) serves as the gold standard diagnostic imaging tool in PE. However; inappropriate use of pulmonary CTA may lead to unnecessary radiation exposure, contrast exposure, and cost. Based on our review of the literature, there is no existing data regarding prevalence and appropriate use of pulmonary CTA in suspected acute PE in Thailand...

Pulmonary embolism is an acute and potentially life-threatening condition requiring a differentiated diagnostic algorithm. Assessment of the risk and clinical probability are of utmost importance in order to initiate early treatment or to reliably exclude a pulmonary embolism. Computed tomography of the pulmonary arteries (CTPA) has become the non-invasive gold standard for the diagnostic approach. Alternatively, scintigraphy can also be used. A negative CTPA excludes a pulmonary embolism with a high degree of probability...

PURPOSE: Diagnostic prediction models such as the Wells rule can be used for safely ruling out pulmonary embolism (PE) when it is suspected. A physician's own probability estimate ("gestalt"), however, is commonly used instead. We evaluated the diagnostic performance of both approaches in primary care. METHODS: Family physicians estimated the probability of PE on a scale of 0% to 100% (gestalt) and calculated the Wells rule score in 598 patients with suspected PE who were thereafter referred to secondary care for definitive testing...

BACKGROUND: A study conducted at an Australian hospital between 2007 and 2009 led to the implementation of a clinical prediction algorithm for pulmonary embolism (PE) consisting of the Wells criteria and D-dimer testing. Since then, studies conducted in other countries have recommended new D-dimer cut-offs to the algorithm. AIMS: To appraise the implemented algorithm and see if its ability to stratify patient risk has been maintained and to test retrospectively new D-dimer thresholds...
