A trachea is a tubular structure composed of smooth muscle that is reinforced with cartilage rings. Some diseases can cause sagging in smooth muscle and cartilaginous tissue. The end result is reduction (narrowing) of the trachea diameter. A solution to this problem is the use of tracheal stents, which are small tubular devices made of silicone. One is inserted into the trachea to prevent or correct its constriction. The purpose of tracheal stent use is to maintain cartilage support that would otherwise be lost in the airway...

Pulmonary artery sling (PAS) is a rare disease frequently associated with severe malacia and stenosis of the trachea. We present a two-day-old newborn that underwent urgent surgery for PAS and needed prolonged respiratory support afterward. Temporary airway stenting above the level of the tracheal bifurcation was performed five days after surgery to overcome severe airway obstruction caused by tracheomalacia and laceration of the tracheal mucosa after diagnostic bronchoscopy. Two days after the procedure, the child could be extubated and after two weeks the stent was removed without complications...

The use of venovenous extracorporeal membrane oxygenation (VV-ECMO) has traditionally been limited to a narrow set of clinical circumstances, such as acute hypoxic respiratory failure, submassive pulmonary embolism, and cardiopulmonary collapse. Within the pediatric population, there have been cases of VV-ECMO in the context of extrinsic airway compression by a mediastinal mass, typically in the setting of either a lymphoma or germ cell tumors. However, the use of VV-ECMO for adults with extrinsic airway compression is comparatively limited...

RATIONALE: Airway stenting is a well-established method that relieves symptoms and maintains airway patency in patients with airway obstruction. Serious complications caused by airway stents such as stent dislocation and airway obstruction during surgery are life-threatening. PATIENT CONCERNS: An 80-year-old man was treated with bronchial stent for left bronchus obstruction caused by metastatic esophageal cancer. During tracheostomy surgery, he suffered from acute tracheal obstruction caused by dislocated bronchial stent...

Through a tracheostomy with a rigid esophagoscope in the esophagus, the authors simultaneously placed self-made magnetic twin stents in a critically ill patient with high tracheoesophageal fistula. The operation took 17 minutes. Oral nutrition was started immediately. The stents were checked and changed after the months 3, 7, and 14. At 18 months, a tracheal resection and esophageal reconstruction through a partial median sternotomy was completed successfully. The magnetic twin stent technique can temporize critically ill patients with an acquired nonmalignant tracheoesophageal fistula until they become operable...

Since the middle of 2014, totally four tracheal silicon stent implantation were performed in our center. Of them, one case was recurrent tracheoesophageal fistula and the other three cases were tracheomalacia. Specifically, parents' psychological support, infants' nutrition support and airway care were key responses for a nurse before implantation. During the procedure of stent implantation, it was responsible for a nurse to closely monitor the infants and to support operator. After the implantation, airway care and prevention of intra-airway bacterial colonization were important to avoid complications such as hemoptysis or hemorrhage, airway obstruction, and stent displacement...

Extended tracheo-bronchoplastic resection for lung cancer with carinal involvement ranks among technically demanding procedures. Despite certain progress in oncological therapy, this type of resection remains the only potentially curative treatment of NSCLC in this localization. However, given the severity of complications postoperative mortality is relatively high (711%). The main cause of death is tracheobronchopleural fistula complicated by thoracic empyema, bronchopneumonia and septic shock. If ARDS (acute respiratory distress syndrome) develops, the mortality rate rises up to 70%...

Silicone tracheobronchial stents are being increasingly used in a large number of patients for the treatment of tracheal stenosis. One very rare complication due to tracheobronchial stenting is bronchoesophageal fistula (BEF), which has been associated with the use of metallic stents. We report intraoperative management of a patient undergoing repair of a BEF, following previous insertion of a silicone Y-stent that is soft in texture and has not been implicated for this complication till date. In addition, misalignment of this silicone tracheobronchial Y-stent resulted in a tracheal mucosal bulge proximal to the stent that vanished after its removal...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...

BACKGROUND: Airway obstruction or tracheoesophageal fistula (TEF) near the tracheal carina requires placement of Y-shaped stents. Herein, we describe our multicenter experience with the placement of Dumon silicone Y-stents. We also conduct a systematic review for studies describing the deployment of airway silicone Y-stents. METHODS: This was a retrospective analysis of consecutive subjects who underwent placement of silicone Y-stents. The clinical details including the underlying diagnosis, indication for the placement of silicone Y-stents, success of stent placement, and follow-up are presented...

BACKGROUND: Management of severe central airway obstruction due to advanced cancer is a medical and technical challenge. The impact of airway stenting on the clinical outcome of such patients is unclear. METHOD: This single-center, retrospective study evaluated 21 patients who underwent airway stenting for advanced cancer. We examined predictors of the post-stenting mortality, including age, serum albumin, tracheal diameter, smoking, opioid use, respiratory failure, and performance status (PS)...

PURPOSE: The literature is devoid of a comprehensive analysis of silicone airway stenting for benign central airway obstruction (BCAO). With the largest series in the literature to date, we aim to demonstrate the safety profile, pattern of re-intervention, and duration of silicone airway stents. METHODS: An institutional database was used to identify patients with BCAO who underwent rigid bronchoscopy with dilation and silicone stent placement between 2002 and 2015 at Rush University Medical Center...

OBJECTIVES: Recurrent congenital tracheoesophageal fistula (TEF) is well documented in infancy but may also present later in life. This study reviews our experience with the clinical presentation, diagnosis and management of 5 recurrent and 2 primary congenital tracheoesophageal fistulas (TEF) in adult patients. There are no literature series of late recurrence of TEF (repaired in childhood and recurring in adulthood) and relatively few reported cases of initial adult presentation of TEF...
