Pulmonary Vascular Disease Flashcards
pathogenesis of pulmonary embolism
thrombus forms in venous system usually in deep veins of legs and embolisms to the pulmonary arteries. can be fatal if massive
principles of management of pulmonary vascular diseases.
anticoagulation
pathogenesis of pulmonary infarction
some of the lung tissue does not receive enough oxygen from blood flow due to clot
pulmonary hypertension
elevated blood pressure in the pulmonary arterial tree. mean pulmonary artery pressure of more than 25mmHg
the major causes of pulmonary hypertension (GROUPS)
idiopathic 1, secondary to left heart disease2, secondary to chronic respiratory disease 3, chronic thromboembolic pulmonary hypertension 4, miscellaneous 5
diagnostic investigative procedures used in pulmonary vascular disease.
wells score, revised Geneva score, full blood count, blood gases, chest X ray, ECG, V/Q scan, CTPA, D dimer test, echocardiography, CT abdomen/ mammography/test for thrombophilia??
principles of management of pulmonary vascular diseases.
heparin, Direct Oral anticoagulants eg rivaroxaban, apixaban, oxygen, warfarin, pulmonary embolectomy
prognosis of PE
PESI score, can be up to 25% mortality rate
vessel that is affected most by hypertension
pulmonary artery and branches of pulmonary artery
symptoms of hypertension
exertion dyspnoea, chest tightness, exertion pre syncope or syncope, haemoptysis
signs of hypertension
elevated JVP, right ventricular heave, loud pulmonary second heart sound, hepatomegaly, ankle oedema
investigations of hypertension
ECG, lung function tests, chest Xray, echocardiography, V/Q scan, CTPA, right heart catheterisation
right heart catheterisation why
allows direct measure of pulmonary artery pressure, measurement of wedge pressure, measurement of cardiac output, vasodilator trial
treatment of hypertension
treat underlying condition, oxygen, anticoagulation, diuretics
specific treatment of hypertension
calcium channel antagonist, prostaglandins, thromboendarterectomy, lung or heart transplant if severe.
