CXR cases Flashcards
calcified pleural plaques from prior asbestos exposure.
Buzz word = “holly leaf” configuration
typically 20 yr latency period between asbestos exposure and pleural plaque formation. They are asymptomatic
NOT considered pre-malignant
PICC line in azygos vein
most common complication = venous rupture
most commonly occurs after LEFT sided placement
27 yoM, trauma. Abnormality in what mediastinal compartment?
displacement of the RIGHT paraspinal line implies abnormality in the posterior mediastinum. In the setting of trauma this most likely is secondary to a paraspinal hematoma in the setting of a vertebral body fracture.
posterior junction line is more superior than the anterior junction line
emphysema
- overinflation of the lungs (flattening of the diaphragms)
- “vascular pruning” at the periphery.
aortic valve
name the three valves that are replaced
IABP too low
The intra-aortic balloon pump (IABP) is a mechanical device that increases myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction.
It consists of a cylindrical polyurethane balloon that sits in the aorta, approximately 2 centimeters (0.79 in) from the left subclavian artery.
The balloon inflates and deflates via counter pulsation, meaning it actively deflates in systole and inflates in diastole.
Systolic deflation decreases afterload through a vacuum effect and indirectly increases forward flow from the heart.
Diastolic inflation increases blood flow to the coronary arteries via retrograde flow.
These actions combine to decrease myocardial oxygen demand and increase myocardial oxygen supply

impella
An Impella is a small, temporary heart pump, attached to a transfemoral (or axillary) catheter.
It is intended for short term use (from 6 hours to < 14 days, depending on the type) during high risk PCI or in patients recovering from AMI cardiogenic shock.
The Impella’s inlet is placed in the left ventricle, where blood is apirated and delivered to the outlet which is situated in the ascending aorta.
The Chest X-Ray shows correct placement of impella with inlet (yellow arrow) and outlet (white arrow) in the left ventricle and acsending aorta.
pulmonic vlave
mitral clip
where is the mass located?
retrotracheal and POSTERIOR
this is the cervicothoracic sign
where is this located?
anterior mediastinum
mass is BELOW the clavicles
where is the mass located in the lungs?
posterior lung
where is this mass located?
extra-pulmonary
probably in the pleural space
left upper lobe collapse
bronchopleural fistula, aka bronchial stump leak
sarcoidosis grading
only on XRs!!
