this study was conducted to determine the prevalence of pe in patients with v/q scans interpreted as representing a very low probability (vlp) of pe (1-3 small segmental perfusion defects with a normal chest radiograph). an analysis of the entire data set obtained during the pioped study was performed. of the total of 1,359 patients in whom the presence or absence of pe was confirmed, 80 (6%) p...

introduction: capnography, is an easy, fast and practical method which its application in the diagnosis of pulmonary thromboendarterectomy (pte) has recently been studied. this study aimed to assess the diagnostic value of end-tidal co2 (etco2) and the alveolar dead space (avds) in the diagnosis of patients suspected to pte who have been referred to the emergency department. materials and metho...

introduction: oral contraceptives (ocs) are considered as one of the most common risk factor of venous thromboembolism (vte) in child bearing age. some of the recent researches indicate that the odds of vte may be even higher with newer generations of ocs. the present meta-analysis was designed to evaluate the effect of different generation of ocs on the occurrence of vte. methods: two research...

a 22-year-old woman presented with acute left-sided pleuritic chest pain and dyspnea 6 days after surgery for revision of the stenotic central aortopulmonary shunt. she had a history of tetralogy of fallot (tof), pulmonary valve stenosis, ventricular septal defect and major aortopulmonary collateral artery. her waterston shunt was placed when she was 5 years old and stented and re-dilated after...

aims: the revised geneva score (rgs), a standardized clinical prediction rule for pulmonary embolism (pe), was recently developed. we have measured its predictive accuracy, performing an external retrospective validation in a cohort of emergency department (ed) patients, filtered by symptomatology and not by clinical suspicion, to allow its use in nursing practice.   methods: the clinical proba...

patients and methods using current procedural terminology (cpt) codes for orthopaedic trauma procedures, we identified a prospective cohort of patients from the 2006 to 2013 acs-nsqip database. using wilcoxon-mann-whitney and chi-square tests where appropriate, patient demographics, comorbidities, and operative factors were compared between patients who developed a dvt within 30 days of surgery...

BACKGROUND Tumor markers (TMs) and D-Dimer are both hallmarks of severity and prognosis of lung cancer. Tumor markers could be related to pulmonary embolism (PE) in lung cancer. RESULTS The number of abnormal tumor markers of lung cancer patients with pulmonary embolism (3.9 ± 1.1vs1.6 ± 0.6,P 0.005) was more than that in patients without pulmonary embolism. TMs panel (P trend < 0.001), CEA (...

BACKGROUND AND OBJECTIVES Pleuritic chest pain, a symptom of pulmonary embolism, is a common presenting symptom in the emergency department. The aim of this study was to validate an algorithm for the diagnosis of pulmonary embolism in emergency department patients with pleuritic chest pain. METHODS This was a prospective, diagnostic cohort study conducted in a large UK city centre emergency d...

BACKGROUND Survival after surgical embolectomy for massive postcesarean pulmonary embolism causing sustained cardiac arrest is rare. CASE One day after an uneventful cesarean delivery, a woman developed cardiac asystole and apnea due to pulmonary embolism. Femoral-femoral cardiopulmonary bypass performed during continuous cardiopulmonary resuscitation allowed a successful embolectomy. Upon aw...

BACKGROUND Pulmonary embolism has become the third most common cardiovascular disease, which can seriously harm human health. OBJECTIVES To investigate the diagnostic value of dual-source computerized tomography (CT) and perfusion imaging for peripheral pulmonary embolism. PATIENTS AND METHODS Thirty-two patients with suspected pulmonary embolism underwent dual-source CT exams. To compare t...
