PE Flashcards
PE mortalilty with and without treatment?
With- 2-8%
Without- 25-30%
Which veins are mostly affected when talking about DVT?
Superficial femoral
Popliteal
Posterior tibial
Peroneal
Virchow’s triad
Stasis
Hypercoagulability
Wall injury
PE classic triad of symptoms
Dyspnea
Pleuritic chest pain
Hemoptysis
Common signs in patient with PE
Tachypnea Rales Increased pulmonary 2nd heart sound Tachycardia Fever Sweating Edema of lower extremity
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 f 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
Non pharmacological treatment for Pe
Catheter embolectomy
Heparin MOA
Binds antithrombin-III
Why will we give LMW heparin?
Doesnt require lab control
Home therapy
Lower bleeding complication
Vit. K antagonist example
Warfarin
Lab control of people on Warfarin?
INR= 2-3
Types of PE
Acute massive PE
Subacute PE
Acute minor PE
Chronic thromboembolic pulmonary hypertension (CTEPH)=
Complication of pulmonary embolism and a major cause of chronic PH leading to right heart failure and death
Common imaging techniques for PE
Ventilation/perfusion scintigraphy
CT angio***
ECG (S1Q3T3)
Pulmonary aniography
PE classic triad
Dyspnea
Hemoptysis
Pleuritic chest pain
