Nils Westermark
Nils Johan Hugo Westermark (1892 - 1980) was a Swedish radiologist. Westermark sign (1938) of relative oligemia on CXR in pulmonary embolism

Pulmonary Embolism: Next Generation
Lauren Westafer introduces the concept of a new generation of pulmonary embolism (PE). What was once considered a deadly disease process now carries a mortality rate of <3%, which may be driven by overtesting as well as overdiagnosis.
Fleischner sign
Fleischner sign: prominent dilated central pulmonary artery. Enlargement can be associated with massive embolus enlarging the luminal diameter of the proximal artery in the acute setting; or pulmonary hypertension in the subacute to chronic setting
Palla sign
Palla sign (1983) right descending pulmonary artery enlargement and 'sausage-shaped' appearance as a potential sign of pulmonary embolism on chest XR
Hampton hump
The Hampton hump is a well-defined pulmonary pleural based opacity representing hemorrhage and necrotic lung tissue in a region of pulmonary infarction caused by acute pulmonary embolism.
ECG Case 104
This ECG is from a 47 year old female. She presents with acute onset severe dyspnoea. Her vitals signs are BP 95/42; RR 30; sats 88% (room air) Describe and interpret this ECG
Ultrasound Case 079
Presentation A previously well 49 year old man presents with chest pain. He is tachycardic, tachypneoic and hypoxic with blood pressure 110 He is 2 weeks post ankle surgery. Describe and interpret these scans
Electrocardiographic Exigency
A 23 year-old man had an episode of syncope at home. He is in severe respiratory distress, extremely pale, dripping with sweat. ECG Exigency
Bedside Echo in Pulmonary Embolism
A 35 year-old female is brought to the emergency department after collapsing in a shopping centre. McConnell sign
Thrombolysis for submassive pulmonary embolus
The use of thrombolytics for the treatment of submassive PE is controversial — the limited documented benefit (e.g. improved hemodynamics, potential for less chronic pulmonary hypertension) must be weighed against the increased risk of life-threatening hemorrhage and the availability of other therapies (e.g. catheter-directed thrombolysis or clot retrieval)
Pulmonary Embolism
Pulmonary embolism (PTE, PE) ranges from asymptomatic to a life threatening catastrophe. PE occurs when a deep vein thrombosis migrates to the pulmonary arterial tree
Alteplase (rtPA)
Alteplase is a tissue plasminogen activator used as a thrombolytic medication in: Acute Ischaemic Strokes, Acute Myocardial Infarction and PE
