Interventional treatment of post tracheostomy tracheal stenosis in neurological rehabilitation: results of a single-center registry.

PMID 41908175WHAT IT FOUND
Interventional treatment for post-tracheostomy tracheal stenosis enabled 77.3% of neurological patients to be decannulated.
Most required only one session, and no procedure-associated complications occurred. Cryoablation was the primary method used, though prednisolone alone helped some patients.
Key findings
0177.3% of patients were successfully decannulated after interventional treatment for post-tracheostomy tracheal stenosis.
02The majority of patients (68.2%) required only a single interventional session, with cryoablation being the most frequent modality.
03No procedure-associated complications were reported across 198 interventions.

What it does not show
Single-center design with potential selection bias limits generalizability. Short follow-up period (mean 66 days) prevents assessment of long-term recurrence. Incomplete data on tracheal cartilage fractures (missing in 37.9% of patients) due to referrals. All stenoses were subglottic type, so results may not apply to other PTTS locations.

The easy way to misread this
Do not assume that interventional treatment alone guarantees decannulation. A significant portion of patients remained tracheostomy-dependent due to neurological factors like dysphagia and secretion burden, not airway obstruction. Assess neurological readiness for decannulation separately from airway patency.
