Bridging silicone and metallic stents for tracheobronchial stenosis in relapsing polychondritis: A case report

Relapsing polychondritis is a rare autoimmune disease that commonly leads to tracheobronchial stenosis, presenting significant treatment challenges.

This case report describes a 64-year-old male with relapsing polychondritis who developed severe tracheobronchial stenosis.

Computed tomography scanning revealed stenosis of the trachea and bronchi, while bronchoscopy confirmed occlusion or stenosis.

Initially, the patient presented with chest pain, fever, and dyspnea. After treatment with corticosteroids and immunosuppressants, fever and chest pain improved, though dyspnea persisted. A silicone stent was inserted, leading to a significant improvement in dyspnea. However, due to granulation tissue hyperplasia at the lower edge of the left main bronchus stent, a metallic stent was used to bridge with the silicone stent 4 years later.

The patient has been followed for 7 years with stable disease control.

For complex airway stenosis caused by relapsing polychondritis, combined placement of silicone stent and metal stent may be considered as a therapeutic option.
