Hampton hump
Hampton hump refers to a dome-shaped, pleural-based opacification in the lung most commonly due to pulmonary embolism and lung infarction (it can also result from other causes of pulmonary infarction (e.g. vascular occlusion due to angioinvasive aspergillosis).
Although uncommon, it can be seen...
Article
Knuckle sign (pulmonary embolism)
The knuckle sign refers to the abrupt tapering or cutoff of a pulmonary artery secondary to a pulmonary embolus (PE). It is better visualized on CT pulmonary angiography (CTPA) than chest x-ray. This is an important ancillary finding in pulmonary embolism, and often associated with the Fleischne...
Article
Geneva score
The Geneva score is a clinical decision rule used to estimate the pre-test probability of pulmonary embolism (PE) in patients in which this diagnosis was considered. The criteria were originally published by the clinical team of the Geneva University Hospital in 2001 1, and revised and simplifie...
Article
Wells criteria for pulmonary embolism
The Wells criteria for pulmonary embolism is a risk stratification score and clinical decision rule to estimate the probability for acute pulmonary embolism (PE) in patients in which history and examination suggests acute PE is a diagnostic possibility. It provides a pre-test probability which, ...
Article
Massive pulmonary embolism
A massive pulmonary embolism (PE) represents the most severe manifestation of venous thromboembolic disease and causes acute right ventricular outflow obstruction which can be fatal. The source is sometimes a clinically silent free-floating lower limb thrombus originating from the soleal intramu...
Article
McConnell's sign (echocardiography)
The McConnell's sign describes a regional pattern of acute right ventricular dysfunction on transthoracic echocardiography first observed in a cohort of patients with acute pulmonary thromboembolism. In contrast to the global wall motion abnormalities observed in chronic right ventricular dysfun...
Article
60/60 sign (echocardiography)
The 60/60 sign in echocardiography refers to the coexistence of a truncated right ventricular outflow tract acceleration time (AT <60 ms) with a pulmonary arterial systolic pressure (PASP) of less than 60 mmHg (but more than 30 mmHg). In the presence of right ventricular failure, it is consisten...
Article
Mercury embolism
Mercury embolism is a rare condition caused by the embolism of elemental mercury secondary to suicidal or accidental intravenous injection 1,4.
Pathology
Etiology
Mercury embolism is primarily from intravenous injection of elemental mercury although it has rarely been seen secondary to inges...
Article
Years criteria for pulmonary embolism
The YEARS criteria is a diagnostic algorithm that determines the risk of pulmonary embolism (PE) derived from three items in the Wells score that are most predictive of PE1. Unlike the Wells score, it uses a variable D-dimer threshold based off clinical pre-test probability. The YEARS criteria i...
Article
N-butyl-2-cyanoacrylate pulmonary embolism
N-butyl-2-cyanoacrylate pulmonary embolism is a potentially life-threatening complication that can arise following the use of the tissue glue, butyl-cyanoacrylate, for endoscopic sclerotherapy to treat variceal bleeding.
Epidemiology
Sclerosis with biological glue (butyl cyanoacrylate) is curr...
