Penetrating Thoracic Injuries

Andrew L. Singer

January 18, 2005

primary survey
Primary Survey
  • Airway
  • Breathing
  • Circulation
anatomic structures
Anatomic Structures
  • Chest Wall
  • Thoracic Vertebrae and Cord
  • Diaphragm
  • Mediastinal Structures
    • Heart
    • Aorta
    • Great Vessels
    • Aerodigestive Tract
  • Pulmonary Parenchyma
diaphragm
Diaphragm
  • Muscular, dome-like structure
  • Separates abdomen from the thoracic cavity
    • Affixed to the lower border of the rib cage
    • Central and superior margin extends to the level of the 4th rib anteriorly and 6th rib posteriorly
    • Major muscle of respiration
      • Draws downward during inspiration
      • Moves upward during exhalation
hemothorax11
Hemothorax
  • Tube thoracostomy is adequate treatment in the majority of patients with traumatic hemothorax
  • The pressure of the pulmonary paranchymal circulation is low and is readily tamponaded with thoracostomy re-expansion
  • Thoracotomy for massive bleeding
    • >1500 mL initial output
    • >200 mL/h for 4 hours
surgical exploration
Surgical Exploration

The choice of position and surgical approach is dictated by the nature of the patient’s thoracic injuries, the certainty of diagnosis, and potential for associated injuries involving other body sites.

anterolateral thoracotomy
Anterolateral Thoracotomy
  • Aortic crossclamping
  • Emergent decompression of pericardial tamponade
  • Open cardiac massage
  • Allows access to abdomen and contralateral side (clamshell)
median sternotomy
Median Sternotomy
  • Preferred Exposure to Heart and Aortic Arch and Great Vessels
  • Difficult Exposure to Lungs, Descending Aorta, Diaphragm and Esophagus
posterolateral thoracotomy
Posterolateral Thoracotomy
  • Makes access to contralateral side and abdomen nearly impossible
  • Provides optimal exposure to the contents of a particular hemithorax
    • Mid-esophageal injuries best approached from right side
    • Descending aorta from left
    • Repair of pulmonary vasculature and airway injuries
additional surgical approaches
Additional Surgical Approaches
  • Subxiphoid pericardial window
  • Diagnostic and/or therapeutic laparoscopy to assess diaphragmatic injuries
