stenosis tracheal

Tae-Ki Lee, Jong-Min Kim, Seok Hwa Choi
BACKGROUND: A long-segmental tracheal lesion is difficult to repair by tracheal allotransplantation due to the lack of a well-defined blood supply for blood vessel anastomosis. The donor trachea needs to be revascularized within a well-vascularized soft tissue flap for several months to allow successful trachea allotransplantation. To date, xenotransplantation using the wild-type or genetically modified pig has been widely studied. The object of this study was to evaluate the feasibility of a small-sized (2 × 2 cm) wild-type pig tracheal patchy in a dog tracheal defect model before trying a long-segment tracheal defect model and using a genetically modified pig as a donor in dog xenotransplantation...

Chondrodysplasia punctata (CDP) is a group of skeletal dysplasias characterized primarily by punctate calcifications in cartilage. It is a rare disease with an incidence of 1:100,000 live births. Extensive airway involvement with calcification of tracheal, bronchial, and thyroid cartilage in CDP is an infrequent finding. We aim to report a case of CDP with characteristic radiological features and severe airway involvement.

The outcomes of tracheal transplantation for the treatment of airway stenosis are unsatisfactory. We investigated the feasibility of regeneration of the trachea using a rat decellularized tracheal scaffold and mouse induced pluripotent stem (iPS) cells for in vivo transplantation. The rat trachea was first decellularized using a detergent-enzymatic treatment method. We successfully established a centrifugation method that can transplant cells onto the luminal surface of the decellularized rat tracheal scaffold circumferentially...

PURPOSE: Congenital tracheal stenosis (CTS) is rare and challenging. Complete tracheal rings cause a wide spectrum of airway-obstructing lesions and varying degrees of respiratory distress. Although surgical reconstruction is the primary option for symptomatic CTS, sometimes an appropriate management strategy may be difficult due to other anomalies. We aimed to identify pitfalls in the management of CTS. METHODS: We retrospectively reviewed the records of patients with CTS during the last 10 years in our institution...

OBJECTIVES: The utility of topical mitomycin C (MMC) as an adjuvant treatment in the management of laryngeal and tracheal stenosis has been studied; however, the ideal timing of MMC application has not been fully elucidated. There is a paucity of studies evaluating the timing of MMC application after surgical airway intervention for stenosis. The purpose of this study is to describe a novel technique for MMC application that allows for delayed application in the unsedated, office-based setting, approximately one week following endoscopic airway dilation...

Background: Geleophysic dysplasia is a rare multisystem disorder that principally affects the bones, joints, heart, and skin. This condition is inherited either in an autosomal dominant pattern due to FBN1 mutations or in an autosomal recessive pattern due to ADAMTSL2 mutations. Two patients with unaffected parents from unrelated families presented to their endocrinologist with severe short stature, resistant to growth hormone treatment. Routine endocrine tests did not reveal an underlying etiology...

Silicone airway stents are extremely useful for both temporary or long-term management of upper airway obstruction, especially in the proximal half of the trachea and in the subglottic region. They cannot migrate are well tolerated, relatively easy to manage, durable, and generally cause little or no injury to the underlying airway mucosa. They are particularly important as part of the management of subglottic strictures. For patients with postintubation tracheal or laryngotracheal stenosis they can be used to temporize for periods up to a year or two, until the patients' condition is optimal for proceeding with a resection or reconstruction...

BACKGROUND: Our objective was to describe the prevalence and characteristics of tracheal lesions observed in flexile bronchoscopies of tracheostomized patients, and to determine those factors associated with severe injuries. METHODS: This is an analytical, observational, and transversal study. The flexible bronchoscopies of tracheostomized patients from our database were reviewed to assess their lesions. The tracheal lesions were classified according to their severity; lesions obstructing above 50% of the lumen were interpreted as severe and those obstructing <50% as mild...

The selection of an appropriately-sized tracheal tube is of critical importance in paediatric patients to reduce both the risk of subglottic stenosis from a tracheal tube that is too large, and inadequate ventilation or poor end-tidal gas monitoring from a tracheal tube that is too small. Age formulae are widely used, but known to be unreliable, often resulting in a need to change the tracheal tube. Previous work has shown that the length of the middle finger and the internal diameter can both be used to guide depth of tracheal tube insertion...

Benign tracheoesophageal fistula (TEF) results from an abnormal communication between the posterior wall of the trachea or bronchi and the adjacent anterior wall of the esophagus. It can be acquired or congenital. The onset of the TEF has a negative impact on the patient's health status and quality of life because of swallowing difficulties, recurrent aspiration pneumonia, and severe weight loss. Several acquired conditions may cause TEF. The most frequent is prolonged orotracheal intubation (75% of the cases)...

Background: Airway management in tracheal resections presents many challenges. The aim of this retrospective analysis is to report the efficacy and complications associated with the use of the laryngeal mask airway in this procedure. Methods: The charts of 54 consecutive patients operated for tracheal stenosis during the period 2009-2016 were reviewed. This cohort included only resections of the trachea. We evaluated total success rate of laryngeal mask insertion (%), insertion success rate on the first attempt, the quality of intraoperative ventilation through the laryngeal mask, the quality of fibre optic view through the device, incidence of bleeding during the first 24 h, signs of dehiscence of the anastomosis within 48 h and 30-day mortality...

Laryngotracheal stenosis comprises a broad spectrum of congenital and acquired conditions that commonly cause pediatric airway obstruction. Although the majority of these conditions were historically managed with endoscopic dilations, the introduction of operative procedures such as laryngotracheoplasty, cricotracheal resection, and slide tracheoplasty changed the treatment paradigm. The gradual evolution of endoscopic technology enabled surgeons to perform certain procedures endoscopically that were previously only able to be performed in an open fashion...

We report the anesthetic management of a 65-year-old woman with recurrent, severe tracheal stenosis who underwent tracheal dilatation. She had visited the Department of Respiratory Medicine at our hospital for respiratory distress approximately 20 years ago, and had undergone laser ablation under local anesthesia. Because of recurrence and aggravation of respiratory distress, she now presented at the Department of Thoracic Surgery, and was scheduled for surgery. Percutaneous cardiopulmonary support was prepared, and she was sedated with midazolam and dexmedetomidine...

INTRODUCTION: Osteochondroplastic tracheobronchopathy (OCTB) is a rare disorder of unknown cause that affects the tracheobronchial tree. It is characterized by multiple cartilaginous formations or bone nodules projecting into the tracheal or proximal bronchial lumen. It is usually asymptomatic because of the slow progression of the nodules. However, chronic cough, recurrent hemoptysis or recurrent respiratory infections have been reported. OBSERVATIONS: We describe the cases of three patients with symptomatic OCTB: two men and one woman consulting for bronchial infections or pneumonia with sputum difficulties (2 cases) or simply for chronic cough (1 case)...

BACKGROUND AND OBJECTIVES: Aortic stenosis is the most common type of heart valve disease. Percutaneous aortic valve replacement has become the alternative for patients considered at high risk for surgery. Controlled mechanical ventilation with tracheal intubation has been the choice for this type of procedure, however the use of noninvasive ventilation in cardiac patients has shown to be beneficial. Janus is a novel full-face mask that allows application of noninvasive ventilation support during anesthesia...
