Successful Use of Pulmonary Cryotherapy for Tracheobronchial Thrombus Extraction and Recanalization of the Tracheobronchial Tree During a Pediatric Venovenous Extracorporeal Membrane Oxygenation Run

Abstract

Impacted pediatric tracheobronchial thrombus is an uncommon diagnosis. There are no clearly proven therapeutic options for airway casts due to a similar process, plastic bronchitis. Cryotherapy, specifically cryoextraction, has shown potential as a therapeutic option in adults with tracheobronchial thrombus and cast. We describe the novel application of this method in a complex pediatric patient.

Keywords: cryotherapy; pediatric; tracheobronchial thrombus.

Two radiographs of the patient. The left panel shows the radiograph taken on the morning before the first cryotherapy session. The right panel shows the radiograph taken on the morning after the second and final cryotherapy session. A marked improvement in lung aeration was noted in the official radiology report.
