BACKGROUND Chronic thromboembolic pulmonary hypertension after pulmonary embolism is associated with high morbidity and mortality. Understanding the incidence of chronic thromboembolic pulmonary hypertension after pulmonary embolism is important for evaluating the need for screening but is also a subject of debate because of different inclusion criteria among previous studies. We determined the...

Hydatid cyst is a helminth infection. The rupture of a hepatic hydatid cyst in inferior vena cava is a rare and lethal complication. Pulmonary embolism is the commonest manifestation. The diagnosis of hydatid cyst is made by histopathological or serological examination, and imaging may suggest the probability of hydatid cyst. Surgical treatment should be performed with caution and always under ...

CONTEXT Previous studies have evaluated the safety of relatively complex combinations of clinical decision rules and diagnostic tests in patients with suspected pulmonary embolism. OBJECTIVE To assess the clinical effectiveness of a simplified algorithm using a dichotomized clinical decision rule, D-dimer testing, and computed tomography (CT) in patients with suspected pulmonary embolism. D...

Pulmonary embolism (PE) is a very serious condition causing sudden death in about one-third of the cases. Treatment with anti-clotting medications is highly effective but not without complications, while diagnosis has been missed in about 70% of the cases. A major clinical challenge, particularly in an Emergency Room, is to quickly and correctly diagnose patients with PE and then send them on t...

BACKGROUND AND OBJECTIVE Pulmonary embolism is potentially life-threatening in patients with lung cancer, but the clinical studies on patients with lung cancer having asymptomatic pulmonary embolism were barely reported. METHODS Clinical data of patients with lung cancer were obtained from the Department of Respiratory and Critical Care Medicine of Tianjin Chest Hospital during July 2012 and ...

BACKGROUND There are few population-based data regarding the effectiveness of inferior vena cava filter use in the prevention of symptomatic pulmonary embolism. OBJECTIVE To determine the 1-year cumulative incidence of rehospitalization for venous thrombosis or pulmonary embolism among patients with thromboembolism treated with a vena cava filter compared with the incidence in a control popul...

PURPOSE OF REVIEW The purpose of this review is to focus on recent research that has addressed the relative merits of computed tomographic pulmonary angiography (CTPA) and ventilation perfusion (V/Q) scanning for the diagnosis of pulmonary embolism. RECENT FINDINGS Computed tomographic pulmonary angiography is the most sensitive test for the diagnosis of pulmonary embolism and its use has bee...

OBJECTIVES To determine the association between physical inactivity (that is, a sedentary lifestyle) and incident idiopathic pulmonary embolism. DESIGN Prospective cohort study. SETTING Nurses' Health Study. PARTICIPANTS 69 950 female nurses who completed biennial questionnaires from 1990 to 2008. Main outcome measures The primary outcome was idiopathic pulmonary embolism confirmed in med...
