Implantation of stent under local anesthesia for the treatment of tracheal obstruction due to primary tracheal neoplasm: report of five cases

Objective: To investigate the clinical effect of tracheal stenting under local anesthesia for neoplastic tracheal obstruction. Methods: Five patients with primary tracheal neoplasm complicated by tracheal obstruction were enrolled in this study. Under local anesthesia and DSA-monitoring, Ni-Ti memory alloy stent was place in the trachea. The clinical data were retrospectively analyzed. Results: Five Ni-Ti memory alloy stents were used in five patients. Technical success was obtained in all patients. After the procedure the symptom of dyspnea was immediately relieved. The degree of short breath, PaO₂ and PaCO₂ were significantly improved after the treatment. Conclusion: For the treatment of tracheal stenosis caused by primary tracheal neoplasm, the implantation of stent under local anesthesia is clinically safe and technically simple with satisfactory short-term effectiveness.
