Treatment of malignant tracheobronchial stenosis by Dacron mesh-covered Z-stents.
Z-stents partially covered with an expandable Dacron mesh into which epinephrine and thrombin were infiltrated, were used to reopen both mainstem bronchi, stenosed by bronchogenic carcinoma and to deliver hemostatic agents to the lesion. On follow-up 4 and 6 weeks later, airway patency was retained, the tumor surface was compressed, and the glossy surface of the stent suggested that it was covered with mucosa. For treatment of airway stenosis due to cancer invasion, a stent covered with a Dacron mesh sheet is thought to be effective in compressing the tumor and preventing tumor ingrowth into the stent.
