Severe Tracheomalacia in the ICU: Identification of Diagnostic Criteria and Risk Factor Analysis From a Case Control Study

Abstract

STM was associated with prolonged ICU stay. A distal tracheal antero-posterior diameter < 7 mm on a non-intubated CT chest was suggestive of STM that required a confirmatory bronchoscopy. Gastroesophageal reflux disease and obesity were potential risk factors.
