Grassheads in the tracheobronchial tree: two different outcomes

Area of Science:

• Pulmonology
• Foreign Body Aspiration
• Medical Case Studies

Background:

• Vegetable foreign bodies frequently cause pulmonary complications due to airway irritation.
• Barley grass, a grasshead type, is resistant to organic decay, differentiating it from other vegetable foreign bodies.
• Understanding the clinical course of barley grass aspiration is crucial for diagnosing and managing airway foreign bodies.

Observation:

• Two patients presented with aspirated barley grass, differing in entry orientation into the trachea.
• Patient 1: Grasshead entered with the flowering unit first, leading to recurrent pneumonias.
• Patient 2: Stem entered first, resulting in migration, pneumonia, and a brain abscess.

Findings:

• The orientation of barley grass entry into the trachea (flowering unit first vs. stem first) is a critical determinant of clinical outcome.
• While recurrent pneumonias occurred in the first patient, removal resolved the issue.
• In the second patient, endoscopic removal failure led to distal migration, severe pneumonia, and a brain abscess.

Implications:

• This highlights the importance of considering foreign body orientation in pediatric and adult airway emergencies.
• Early and accurate diagnosis of aspirated barley grass is vital to prevent severe complications.
• Further research into endoscopic techniques and management strategies for recalcitrant airway foreign bodies is warranted.
