If high cinical propability that PE happened,
What is the next step?
CT angiography
If low cinical propability that PE happened,
What is the next step?
D-dimer
After positive D-dimer test what will we do?
CT angiography
What is the name of the score for clinical prediction of PE
Wells score
PE is likely when Wells score is
> 2
Components of Wells score
Previous PE/DVT HR > 100 Haemoptysis Immobilization Cancer Signs of DVT
PE abnormal ECG findings
ST depression (50% of cases) Sinus tachy Negative T on V1-2 SVA S1Q3T3 RBBB P-pulmonale (6% of cases)
Laboratory parameters in PE
Elevated D-dimer
Low PaO2
Low PaCO2
Alkalosis
How can we get a definitive diagnosis for PE?
Pulmonary angiography
Absolute contraindication for giving thrombolytic therapy in PE
Active GI bleeding
Intraccranial haemorrhage
