Saber-sheath trachea, a narrowing of the airway, is linked to COPD. A patient experienced airway obstruction post-laryngectomy due to this condition, requiring tracheal dilation for relief.

Area of Science:

  • Pulmonary Medicine
  • Radiology
  • Anatomy

Background:

  • Saber-sheath trachea is an anatomical deformity characterized by coronal narrowing and anteroposterior lengthening of the intrathoracic trachea.
  • This condition is frequently associated with chronic obstructive pulmonary disease (COPD) and chronic bronchitis.
  • Despite suggestive lateral compression, the tracheal cartilage in saber-sheath trachea is typically thickened and calcified.

Observation:

  • A patient presented with progressive airway obstruction due to crusted secretions after a total laryngectomy.
  • The obstruction necessitated emergency room visits and hospital admission.
  • Computed tomography confirmed the presence of saber-sheath trachea as the underlying cause.

Findings:

  • Computed tomography is crucial for diagnosing saber-sheath trachea.

  • Tracheal dilation provided partial symptomatic improvement for the patient.
  • The study discusses diagnostic findings, differential diagnoses, etiologies, and clinical significance of saber-sheath trachea.

    • Implications:

    • Saber-sheath trachea can lead to significant airway obstruction, particularly in post-surgical patients.
    • Early diagnosis and appropriate management, such as tracheal dilation, are important for patient outcomes.
    • Understanding this deformity is vital for managing patients with respiratory compromise and associated conditions like COPD.
