Right-pneumonectomy syndrome: radiologic findings and CT correlation

Area of Science:

• Thoracic Surgery
• Pulmonary Medicine
• Radiology

Background:

• Right-pneumonectomy syndrome is a rare, delayed complication following right lung removal.
• It often occurs in patients who underwent pneumonectomy during childhood or adolescence.

Purpose of the Study:

• To review the clinical, radiographic, and bronchoscopic findings in patients with right-pneumonectomy syndrome.
• To highlight the diagnostic challenges and management strategies for this rare complication.

Main Methods:

• Retrospective review of clinical history, radiographic, and bronchoscopic findings in five patients.
• Utilized computed tomography (CT) and fluoroscopy for imaging.
• Bronchoscopy was used for confirmation.

Main Results:

• Patients presented with dyspnea and recurrent left lung infections.
• Radiographic findings included mediastinal deviation, cardiac rotation, and left lung herniation.
• CT best visualized airway compression, while fluoroscopy and bronchoscopy confirmed tracheobronchomalacia and mediastinal shift.

Conclusions:

• Right-pneumonectomy syndrome can lead to significant morbidity and mortality.
• Accurate radiologic evaluation is crucial for diagnosis.
• Surgical intervention is frequently necessary for effective management.
