THORACIC SECTION 17: TRAUMA Flashcards
Left sided diaphragmatic injury is common thant the right because?
The liver serves as a buffer
Describe most of the diaphragmatic ruptures
“Radial”
Longer than 10 mm
POSTERIOR LATERAL portion
Diagnosis
Sign?
Diaphragmatic injury
Collar sign (Hour-glass sign)
Wist-like appearance of the herniated organ through the injured diaphragm.
Diagnsosis
Sign?
Diaphragmatic inury
Dependent Viscera Sign
- absence of interposition of the lungs between the chest wall and upper abdominal organs
Tracheo-Bronchial inury usual location
2 cm of the carina
Tracheo-Bronchial Injury close to the carina can cause this condition
Pneumomediastinum rathter than pneumothorax
The most common site of injury in the trachea in penetratic trauma
Cervical trachea
The most common site of injury in the trachea in Blunt chest trauma
Distal trachea (2.5 of the carina)
Most common cause of pneumomediastinum in trauma patients
Alveolar rupture from blunt trauma, and the air dissects along bronchovacular shteats.
Macklin effect.
Diagnosis?
Describe
Boerhaave Syndrome
Ruptured esophageal wall from vomiting —> pneumomediastinum/Mediastinitis
When you see air in these locations (white outlines) you need to think about ruptured
1.
2.
- Alveoli
- Ruptured trachea or esophagus.
Name 4 most common cause of pneumopericardium
- Mechenical Ventilation
- Thoracic Surgery
- Penetrating trauma
- Infectious Pericarditis
The difference between Pneumopericardium and Pneumomediastinum
is highly testable.
This is the most common lung injury from blunt trauma. Basically you are dealing with alveolar hemorrhage without alveolar disruption.
