A Case of Idiopathic Tracheal Stenosis Treated with Tracheal Resection After a Retrievable Stent Insertion

심한 호흡부전을 보인 특발성 기관 협착증 환자에서 풍선 확장술 및 기관 스텐트 삽입술을 시행하여 호흡을 안정시킨 후 수술적 절제 및 문합술을 시행하였다.

Idiopathic tracheal stenosis is a type of benign stenosis that possesses specific characteristics but is of unknown origin. It is a rare disease characterized by extensive fibrosis of a portion of trachea, and predominantly found in women. The lesion presents as circumferential fibrotic stenosis that usually occurs at upper trachea and the subglottic larynx, but lower trachea may also be involved. Diagnosis is made from the clinical characteristics accompanide by compatible pathologic features and by exclusion of other etiologies. Conservative management such as laser resection, dilatation and stent insertion can be tried initially, but surgical resection is recommended for definitive treatment due to frequent restenosis and maintenance problems of conservative approach. We report a case of idiopathic tracheal stenosis treated with tracheal resection and anastomosis followed by insertion of a retrievable stent for immediate relief of airway obstruction.
