Answer 17

bilateral hilar lymphadenopathy

Question 18

More than 95% of Pulmonary emboli arise from thrombi in what area of the body?

Answer 18

Deep Vein Thrombosis from the lower legs

- popliteal or femoral veins

Question 19

The consequences of pulmonary embolism depend on size. What are the two important consequences of pulmonary emboli

Answer 19

1) Increase in Pulmonary artery Pressure (HTN)

2) Tissue Ischemia/Infarction

Question 20

Occlusion of a major vessel in the lungs results in what progression of events?

Answer 20

Sudden increased in artery pressure –> Diminished cardiac outpud –> right sided heart failure/cor pulmonale –>hypoxia/death

Question 21

The majority of Pulmonary Emboli are clinically silent (60-80%) and the minority cause acute cor pulmonale or death (5%)

Answer 21

True

What type of embolism is large and may lodge at a bifurcation causing occlusion of more than 60% of pulmonary artery supply

Answer 23

Saddle Embolus

Question 24

where does a saddle embolism usually occur

Answer 24

at the bifurcation of the pulmonary artery

Question 25

Pulmonary hypertension involves what vascular alterations of the entire arterial tree

Answer 25

Atherosclerosis and smooth muscle hypertrophy

Question 26

Pulmonary Hypertension can be primary or secondary, which one is more common?

Answer 26

Secondary

Question 27

What is Pulmonary Hypertension most often secondary to?

Answer 27

A decrease in cross sectional area of Pulmonary vessels or An increase in pulmonary vascular flow

Question 28

Pulmonary blood pressures are usually higher than systemic pressures

Answer 28

False, | Pulmonary pressures are usually only about 1/8th the pressure of systemic circulation
