CT Case 009
A 60yo female presents with 2 weeks of dyspnoea, pleuritic chest pain and bilateral calf tenderness. She is worked up for possible pulmonary embolus

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
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.
Antonio Palla
Antonio Palla (1949 - ) is an Italian respiratory and nuclear medicine specialist. Palla sign in pulmonary embolus (1983)
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
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
