“…Whenever possible, treatment is directed toward the underlying cause of TBM [6]. In localized forms of TBM, surgical options are resection of the malacic segment with reanastomosis [5], external splinting [6], or endoscopic placement of expandable stents in the malacic segment [10]. Aortopexy/tracheo- pexy has been shown to be successful in patients with more extended forms of primary TBM without signs of external compression [4].…”

A neonatal case of severe, ventilator-dependent tracheobronchomalacia (TBM) is described. The extent of the malacic segment was determined by endoscopy and tracheobronchography. Additionally, relevant and ever increasing reversible peripheral airway obstruction was documented by measuring the mechanical properties of the respiratory system before and after salbutamol. With the combination of endoscopically guided aortopexy and salbutamol infusion, the infant was eventually weaned from mechanical ventilation at the age of 86 days. We speculate that in ventilator-dependent infants with severe TBM the determination of bronchodilator responsiveness may have clinical consequences.

“…Stent obstruction by granulation tissue is the most frequent complication of this treatment in children, occurring in 63% of patients [19,20]. According to our experience, cryorecanalization is an interesting new therapeutic option for the treatment of severe stent obstruction in children.…”

We report a 12-year-old boy who underwent stent implantation into the left main bronchus at the age of 9.5 years for palliation of severe bronchial stenosis. He had developed complete obstruction of the stent by granulation tissue resulting in respiratory deterioration and the requirement of mechanical ventilation. The stent obstruction was treated at the age of 11.5 years by cryorecanalization. In this technique, cooling of the tip of the cryoprobe is used to induce adherence of the obstructing tissue allowing the subsequent removal of tissue particles by retraction of the probe. Under general anesthesia, a miniaturized cryoprobe was advanced via the working channel of a flexible bronchoscope. Repeat maneuvers of freezing and retraction resulted in complete recanalization of the stent. Repeat bronchoscopies 4 and 12 weeks later revealed recurrent formation of some granulation tissue which was removed by repeat cryorecanalization. Seven months after the initial procedure there was a complete patency of the stent. According to our experience, cryorecanalization is a safe and effective alternative for the treatment of stent obstruction by granulation tissue. Due to the introduction of a miniaturized probe, this method is well applicable in children since it can be performed via the working channel of a flexible pediatric bronchoscope.

“…[13][14][15][16] Metallic balloon-expandable angioplasty stents have the advantages of small size, accurate placement, and precise luminal diameter. [17][18][19] In this series, the stents were particularly applicable in the treatment of tracheomalacia, which may occur after tracheoplasty. The severity of airway obstruction in our patients and the absence of a reasonable alternative led us to consider endobronchial stenting.…”

“…17,18 In the largest series reported (to our knowledge), Filler et al 19 treated 16 patients with such stents for tracheomalacia, bronchomalacia, stenosis, and airway compression, and successful relief of airway obstruction was achieved in 13 of them. Herein, we present our experience with the use of balloon-expandable stents at Children's Memorial Hospital, Chicago, Ill.…”
