Erler-Zimmer Inhaled Foreign Body in Trachea 3D Printed Model

„Erler-Zimmer GmbH & Co. KG inspired foreign body in trachea 3D model:

• Model Number: MP2053
• Clinical history:
  A 57-year-old man presented with a 3-week history of cough and pleuritic left-sided chest pain. Chest radiography showed left upper ventricular contraction with a large left hemiplegic effusion. Pleurodesis removed pure pus from the pleural cavity. Despite pleural drainage and antibiotic therapy, he subsequently died.
• Pathology:
  This image shows the lower trachea and main bronchi. They have been cut and the left upper ventricle has been cut to expose the incision. A foreign body is lodged in the origin of the left upper ventricle bronchus - an inhaled rabbit vertebra! The obstruction has caused the upper ventricle to contract, pneumonia has developed and the pleural surface is covered with fibrinous exudate. This is an inhaled foreign body with associated left upper ventricular contraction, consolidation of pneumonia and pleural effusion.
• Additional information:
  Foreign body aspiration or foreign body aspiration (FBA) occurs when a foreign object is inhaled into the airways, causing partial or complete obstruction of the airway. It can be potentially fatal. It is more common in children than in adults. It is one of the leading causes of accidental death worldwide. FBA poses the greatest risk of death in those younger than 1 year of age and in patients older than 75 years.
  Risk factors for foreign body aspiration in adults include decreased level of consciousness, drug or alcohol intoxication, or analgesia. Additional risk factors in the elderly include medication use (which interferes with speech and communication), dysphagia due to stroke, and degenerative neurological diseases such as Alzheimer's or Parkinson's disease. In adults, the most common foreign bodies inhaled include inorganic objects (e.g., thorns, pins, dental plaque) and organic matter (e.g., bones, poorly chewed meat, and watermelon seeds). Symptoms at presentation vary depending on the degree of airway obstruction. Large obstructions may present as choking or sudden suffocation. Smaller foreign bodies may present with more insidious symptoms such as cough, dyspnea, fever, chest pain, and hemoptysis. The narrowing of the airway beyond the foreign body will lead to infection. Treatment includes removal of the foreign body with bronchoscopy or emergency tracheostomy.
