Trachea stenosis

A 58-year-old woman presented with a six-month history of nasal congestion, sore throat and cough, and a five-month history of dyspnea. She had a history of xerostomia for one year. On examination, the bilateral submandibular gland and parotid glands were enlarged. Parotid and anterior cervical lymph nodes were palpable. There were rales in both lungs. The rest of the physical examination was unremarkable. Sialographic analysis showed normal caliber in the main duct, stenosis in secondary ducts, and dilation in the proximal ducts...

INTRODUCTION: Endotracheal intubation is a common procedure to maintain an open airway with risks for traumatic injury. Pathological changes resulting from intubation can cause upper airway complications, including vocal fold scarring, laryngotracheal stenosis, and granulomas and present with symptoms such as dysphonia, dysphagia, and dyspnea. Current intubation-related laryngotracheal injury treatment approaches lack standardized guidelines, relying on individual clinician experience, and surgical and medical interventions have limitations and carry risks...

UNLABELLED: Vascular rings are unusual congenital malformations. Among them, double aortic arch (DAA) is often difficult to diagnose due to its low incidence of symptoms. DAA can be associated with tracheal or esophageal compression and, in severe cases, could require tracheal intubation or chronic use of a nasogastric tube. This scenario favors the development of aortotracheal fistulas (ATF) or aortoe-sophageal fistulas (AEF). OBJECTIVE: To present a clinical case with an unusual association of DAA with ATF and to reinforce the importance of maintaining high diagnostic suspicion in patients with massive aerodigestive bleeding without an obvious source...

BACKGROUND: Button battery (BB) ingestions (BBI) are increasingly prevalent in children and constitute a significant, potentially life-threatening health hazard, and thus a pediatric emergency. Ingested BBs are usually charged and can cause severe symptom within 2 h. Discharged BBs ingestion is very rare and protracted symptom trajectories complicate diagnosis. Timely imaging is all the more important. Discharged BBs pose specific hazards, such as impaction, and necessitate additional interventions...

Tracheal stenosis post intubation is one of the most common complication for which resection and anastomosis is done. Here we present a 21 year male patient who was intubated post organophosphorous poisoning. Diagnosed with tracheal stenosis post intubation and managed with tracheal resection and anastomosis with uneventful recovery. Post intubation tracheal stenosis is one of the serious complications and requires a multidisciplinary team and high volume centre for adequate management. Considering the fact that this case report has tracheal stenosis of grade IV type with resected length of tracheal cartilage of more than 3 cm and trachea- tracheal anastomosis makes this a rare case report...

OBJECTIVE: Anastomotic complications after tracheal resection/cricotracheal resection (TR/CTR), such as granulation tissue formation, can lead to severe morbidity. The off-label use of nebulized ciprofloxacin-dexamethasone (Ciprodex) for granulation tissue prophylaxis has anecdotally been used after TR/CTR, especially in pediatric patients. However, its use in the adult population, and its safety and side effect profile post-TR/CTR has not been reported. This study aims to characterize the incidence of adverse side effects associated with nebulized Ciprodex in post-TR/CTR patients...

BACKGROUND: Congenital malformations of the trachea are rare but often life-threatening. Limited data have been published on the outcomes of tracheal reconstruction for congenital tracheal stenosis. We sought to describe the outcomes of patients undergoing tracheal reconstruction over 10 years at our centre. METHODS: All paediatric patients who underwent long-segment tracheal or bronchial reconstruction from January 1, 2012, to August 31, 2022, were included. The primary outcome was mortality, and secondary outcomes included reoperation and postoperative morbidity...

The treatment of long-tracheal lesion is difficult because there are currently no viable grafts for tracheal replacement. To solve this problem, we have developed an autologous Tissue-Engineered Trachea (aTET), which is made up of collagenous tissues and cartilage-like structures derived from rat chondrocytes. This graft induced successful long-term survival in a small-animal experiment in our previous study. In this study, we investigated the regeneration process of an aTET to attain reproducible success. We prepared an aTET by using a specially designed mold and performed patch tracheoplasty with an aTET...

INTRODUCTION: With its introduction in 1986, the use of metal tracheal stents gained favor due to relative ease of deployment and reduced risk of stent migration and mucus plugging. However, adverse events associated with metal stenting led the FDA to publish a recommendation against its use for benign airway stenosis in 2005. We present a case which illustrates the difficulty in removal of a metal stent from the airway. CASE REPORT: Our patient is a 47-year-old woman with a history of postintubation tracheal stenosis...

Most of the small-cell lung cancer patients are of the central type of lung cancer. Small-cell lung cancer often intrudes into the atmospheric tract and large blood vessels, thus causing severe tracheobronchial stenosis and superior vena cava syndrome. In addition, patients with malignant tumors, especially those with respiratory failure and severe hypoxia, can be complicated with thromboembolic diseases. We reported a 65-year-old woman with severe stenosis of the trachea, and right main bronchus complicated with acute respiratory failure was treated with bronchoscopy and stent implantation to improve the patient's dyspnea, thus successfully receiving chemotherapy and timely treatment...

BACKGROUND: Congenital esophageal stenosis (CES) is a rare condition. We encountered a case of esophageal cancer that developed in an adult with persistent CES. Although many studies have investigated the therapeutic outcomes and performed surveillance for symptoms after treatment for CES, few have performed long-term surveillance or reported on the development of esophageal cancer. We report this case because it is extremely rare and has important implications. CASE PRESENTATION: A 45-year-old woman with worsening dysphagia was transferred to our hospital...

OBJECTIVES: Recent immunologic study of the adaptive immune repertoire in the subglottic airway demonstrated high-frequency T cell clones that do not overlap between individuals. However, the anatomic distribution and antigenic target of the T cell repertoire in the proximal airway mucosa remain unresolved. METHODS: Single-cell RNA sequencing of matched scar and unaffected mucosa from idiopathic subglottic stenosis patients (iSGS, n = 32) was performed and compared with airway mucosa from healthy controls (n = 10)...

OBJECTIVES: The management of idiopathic subglottic stenosis (iSGS) poses a clinical challenge due to high recurrence rates following both endoscopic and open approaches, often leading to tracheostomy. The activation of abnormal T-cells and cytokine pathways has been linked to iSGS pathogenesis. Autologous adipose tissue centrifugation yields lipoaspirate, offering optimal anti-inflammatory effects and biocompatibility widely utilized in various medical settings. This report presents the first 3 cases employing endoscopic dilation (ED) in combination with local lipoaspirate injection to address recurrent iSGS...

BACKGROUND: IgG4-related disease is a systemic fibroinflammatory disease that is mainly seen in older men, and involves multiple organs, such as the pancreas and lungs. However, 75% of patients with IgG4-related lung disease are asymptomatic (if they are symptomatic, they mainly complain of nasal congestion, rhinorrhoea, chest pain, and cough) and are incidentally diagnosed through chest computed tomograph. Although, nodules in the airway and bronchial wall thickening are criteria for diagnosis, it is important that nodules have been reported in peripheral airways in several cases and rarely in the central airway...

We report the case of a 66-year-old woman who was diagnosed with localized tracheal amyloid light-chain (AL) amyloidosis caused by an underlying B-cell neoplasm. The diagnosis was confirmed through subsequent bronchoscopy and biopsies; however, she experienced a challenging episode of hypoxic respiratory failure that required intervention. Repeat bronchoscopies showed persistent subglottic stenosis and tracheobronchomalacia, which led to tracheal debulking surgery and additional interventions. The patient's treatment began with rituximab, zanubrutinib, and dexamethasone with outpatient follow-up...

Spondylometaphyseal dysplasia (SMD) is a rare genetic disorder affecting skeletal growth and development presenting anesthesiologists with many perioperative challenges. We present a case of a patient found to have multilevel tracheal stenosis due to twisting and folding of his trachea. This was discovered on imaging during a research review of SMD cases at our institution. Structural and functional abnormalities of the trachea have not been reported in SMD. This is the first description of a patient with SMD with severe multilevel tracheal disease requiring tracheal reconstructive surgery...

BACKGROUND: The most prevalent cyanotic congenital heart disease is Tetralogy of Fallot (TOF). It has a variety of presentations and is made up of four anatomic abnormalities. Documented literature shows an incidence of 13-20% of a right aortic arch with an anomalous left subclavian artery among individuals diagnosed with TOF. This is the first case that discusses the rare occurrence of overriding of the aortic arch along with the left aberrant subclavian artery and vertebral defect in a 3-week-old girl...

The phlorotannin-polycaprolactone-coated endotracheal tube (PP tube) has been developed with the aim of preventing tracheal stenosis that can result from endotracheal intubation, a factor that can lead to a serious airway obstruction. Its preventive efficacy has been assessed through both in vitro and in vivo investigations. However, there is a lack of studies concerning its biocompatibility and sub-chronic toxicity in animal models, a crucial factor to ensure the safety of its usage as a functional endotracheal tube...

Idiopathic subglottic stenosis is a circular scarred narrowing of the airway at the transition from the cricoid cartilage to the trachea. The stenosis is found radiologically and endoscopically at the level of the cricoid cartilage without involvement of the cricoid or tracheal cartilage itself. The disease practically only affects women between the ages of 20 and 60. The same clinical picture occurs in granulomatosis with polyangiitis and less frequently in other autoimmune diseases, where it requires systemic treatment...
