background: safe exclusion and risk stratification are currently recommended for the initial management of patients with acute pulmonary embolism (ape). the aim of this study was to assess the safe exclusion and risk stratification value of d-dimer (dd) for ape when tested at the beginning of admission. materials and methods: all consecutive chinese ape patients and controls were recruited from...

The incidence of pulmonary thromboembolism is hard to assess by the pathologist as a result of seasonal variation of embolism and disappearance of emboli by thrombolysis. However, the great differences in estimates of the incidence in routine hospital autopsies is mainly related to variation in scrutiny of the investigation and in size of area searched microscopically. Obstruction of major pulm...

BACKGROUND Selection of patients for diagnostic tests for acute pulmonary embolism requires recognition of the possibility of pulmonary embolism on the basis of the clinical characteristics. Patients in the Prospective Investigation of Pulmonary Embolism Diagnosis II had a broad spectrum of severity, which permits an evaluation of the subtle characteristics of mild pulmonary embolism and the ch...

PURPOSE OF REVIEW Pulmonary embolism remains one of the leading causes of cardiovascular mortality. The wide range of reported mortality rates reflects heterogeneity in comorbidity and severity of pulmonary embolism. Optimizing risk stratification to prognose pulmonary embolism patients appears to be important to improve management, treatment and clinical outcome. RECENT FINDINGS Hemodynamic ...

Pulmonary embolism is a common and potentially life threatening condition. Delays in pulmonary embolism diagnosis represent an important problem. It is crucial to have early diagnosis of pulmonary embolism if one wishes to reduce its complication. We retrospecttively reviewed our patients who visited our emergency department with a final diagnosis of pulmonary embolism. We found that delayed di...

OBJECTIVE To estimate the incidence and determine the characteristic features of venous thromboembolism in the Hong Kong Chinese population. DESIGN Retrospective study. SETTING Regional hospital, Hong Kong. SUBJECTS AND METHODS Data were collected during a period of four years (1997-2000). Patients with duplex doppler ultrasonography or venography-documented venous thromboembolism and new...

While cardiac involvement is not a common presentation in human echinococcosis, it may lead to life-threatening complications including cyst rupture; anaphylactic shock; tamponade; pulmonary, cerebral or peripheral arterial embolism; acute coronary syndrome; dysrhythmias; infection; ventricular or valvular dysfunction, as well as sudden death. Here we report a 9-year old girl who was diagnosed ...

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...
