Tracheal stenosis diagnosed on pulmonary ventilation/perfusion scan

Area of Science:

• Pulmonary Medicine
• Respiratory Surgery

Background:

• Tracheal stenosis is a known complication following endotracheal intubation.
• Symptoms can be subtle, leading to delayed diagnosis and treatment.

Purpose of the Study:

• To highlight the diagnostic challenges and management of tracheal stenosis.
• To emphasize the importance of considering tracheal stenosis in post-intubation patients.

Main Methods:

• Case report of a 68-year-old woman post-coronary artery bypass surgery.
• Initial misdiagnosis as pulmonary embolism.
• Ventilation/perfusion scan revealing tracheal stenosis.
• Intervention included dilation and endobronchial stent deployment.

Main Results:

• Tracheal stenosis was confirmed as the cause of respiratory symptoms.
• Successful management achieved through dilation and stenting.
• The case underscores the insidious nature of the condition.

Conclusions:

• Tracheal stenosis can present insidiously, mimicking other conditions like pulmonary embolism.
• Early recognition and appropriate diagnostic imaging are crucial for timely intervention.
• Endobronchial stenting is an effective treatment option for managing tracheal stenosis.
