Abstract
Background. Central airway obstruction (CAO) is defined as obstruction of trachea and principal bronchi. Therapeutic rigid
bronchoscopy with tracheobronchial stenting using silicon stents is a well established procedure in the management of such
conditions. However, there is limited experience with this technique in India.
Methods. Between January 2010 and April 2010, Dumon stents were placed in four patients with CAO. Three patients had
symptomatic tracheal stenosis while one patient had malignant obstruction at the carina. Rigid bronchoscopy under general
anaesthesia was performed to relieve the CAO followed by placement of silicon stents. Pre- and post-stent placement symptom assessment was performed with a symptom-based visual analogue scale.
Results. Four patients underwent silicon stent placement in the tracheobronchial tree. Three patients had benign postintubation tracheal stenosis and one had malignant tracheal obstruction at carina due to endobronchial growth. Significant
improvement was achieved in all patients. There were no significant complications.
Conclusions. Rigid bronchoscopy with silicon stent placement is an effective and suitable method of relieving the distressing
symptoms due to benign or malignant airway obstruction.
