BACKGROUND: Elective extra-corporeal membrane oxygenation (ECMO) is rarely used in thoracic surgery, apart from lung transplantation. The purpose of this study was to summarize our institutional experience with the intraoperative use of veno-venous (VV) ECMO in selected cases of main airway surgery. METHODS: We retrospectively analyzed the data of 10 patients who underwent main airway surgery with the support of VV-ECMO between June 2013 and August 2022. RESULTS: Surgical procedures included: three carinal resection and reconstruction with complete preservation of the lung parenchyma, one right upper double-sleeve lobectomy and hemi-carinal resection, and one sleeve resection of the left main bronchus after previous right lower bilobectomy, for thoracic malignancies; four tracheal/carinal repair for extensive traumatic laceration; one extended tracheal resection due to post-tracheostomy stenosis in a patient who had previously undergone a left pneumonectomy...

Tracheal stenosis is a rare but life-threatening disease in preterm infants. Misdiagnosis as congenital tracheal stenosis is common, making surgical management challenging. This report presents a case of a preterm infant with tracheal stenosis and congenital heart malformation treated with ECMO-assisted tracheal resection and end-to-end anastomosis. A male infant was born at 30 weeks of gestation with severe asphyxia, cardiac insufficiency, and pneumonia. Following failed medical treatment, fiberoptic bronchoscopy confirmed mid-tracheal to carinal stenosis...

Pulmonary Mucormycosis is a fatal infectious disease with high mortality rate. The occurrence of Mucormycosis is commonly related to the fungal virulence and the host's immunological defenses against pathogens. Mucormycosis infection and granulation tissue formation occurred in the upper airway was rarely reported. This patient was a 60-year-old male with diabetes mellitus, who was admitted to hospital due to progressive cough, sputum and dyspnea. High-resolution computed tomography (HRCT) and bronchoscopy revealed extensive tracheal mucosal necrosis, granulation tissue proliferation, and severe airway 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...

Tracheobronchial tuberculosis is one of the conditions causing long segment tracheal stenosis and is a clinically challenging scenario. This report describes a successful tracheal reconstruction in a 44-year-old man with long-segment post-tuberculosis tracheobronchial stenosis, utilizing a stented cryopreserved aortic allograft. The procedure was necessitated by the failure of conventional treatments. The stenotic segment was resected and replaced with a cryopreserved aortic allograft, supported by a metallic stent to maintain airway patency...

BACKGROUND: The literature documents that laminoforaminotomy (CLF), whether performed open, minimally invasively, or microendoscopically, is safer than anterior cervical diskectomy/fusion (ACDF) for lateral cervical disease. METHODS: ACDF for lateral cervical disc disease and/or spondylosis exposes patients to multiple major surgical risk factors not encountered with CLF. These include; carotid artery or jugular vein injuries, esophageal tears, dysphagia, recurrent laryngeal nerve injuries, tracheal injuries, and dysphagia...

The presentation of acute and rapidly deteriorating airway pathology can be a highly challenging situation for any hospital team. Cricoid chondromas are a challenging and potentially unfamiliar airway pathology requiring the combined expertise of anaesthetists, ear, nose and throat surgeons and a wider peri-operative team familiar with managing airway emergencies. Airway lesions which cause rigid and fixed stenosis require careful management and present additional challenges compared to soft tissue lesions...

BACKGROUND: Vocal cord polyps are commonly encountered in the otorhinolaryngology department. The risk of anesthesia is high in patients with large vocal cord polyps. Awake intubation with appropriate airway tools provides a favorable safety profile. CASE: We present the case of a 60-year-old male patient who had been suffering from a large vocal cord polyp for 16 years. Electronic laryngoscopy revealed that the vocal cord polyp was approximately 1.5 cm in diameter...

Benign tracheal stenosis (BTS) is a refractory disease with a complex pathogenesis and limited therapeutic drug effects. The management of benign tracheal stenosis remains a major challenge for the interventional physiologist. In recent years, the role of infection in the occurrence and development of tracheal stenosis has attracted some attention, but there is still some controversy. A clear understanding of the relationship between infection and tracheal stenosis is essential to elucidate the pathogenic mechanism of BTS, and then to improve early prevention and management of BTS...

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: To observe the occurrence of related complications after self-expandable metallic (SEM) airway stents implantation with different diameters at different time points, and to provide theoretical basis for the optimal chioce of existing airway stents in clinical practice. METHODS: Healthy New Zealand white rabbits were used to establish benign tracheal stenosis models after chest CT examination. Forty-fivemodel rabbits with more than 50% of airway stenosis were divided into two groups...

OBJECTIVES: We aimed to review the outcomes of treating incidentally encountered asymptomatic airway stenosis during open-heart surgery conservatively without the use of tracheoplasty. METHODS: Between January 2002 and October 2022, 25 patients were incidentally diagnosed with tracheal stenosis during open-heart surgery. Intraoperative bronchoscopy and/or laryngoscopy revealed tracheal stenosis; however, this was not consistent with the findings of the preoperative computed tomography...

UNLABELLED: Tracheal resection and anastomosis is characterized in the last years by significant innovations which are well codified and standardized. Although the mortality rate is markedly reduced, the operation is still not free from risk of complications such as recurrent laryngeal nerve injury, anastomosis dehiscence, granulation tissue formation and restenosis. Pearson FG, Cooper ID, Nelems JL (1975) Primary tracheal anastomosis after resection of the cricoide cartilage with preservation of the recurrent laryngeal nerves...

The objective of this case series was to analyse the complications that arise from tracheostomy procedures conducted in a tertiary healthcare facility throughout a two-year timeframe. Fifteen occurrences of complications were observed out of the 100 tracheostomies that were studied, suggesting a prevalence rate of 15%. The detected complications included subcutaneous emphysema, misplacement of the tube, infection at the surgical site, and tracheal stenosis, among various others. Considerable indications of complication were identified, encompassing variables such as age and a history of head and neck cancer...

BACKGROUND: Airway anomalies, symptoms and interventions are commonly reported in children with oesophageal atresia with tracheoesophageal fistula (OA/TOF). The purpose of this study was to assess the incidence of these airway pathologies and those requiring interventions in the long-term. METHODS: A retrospective case note review of all patients admitted to the Neonatal Unit at the Royal Hospital for Children, Glasgow between January 2000 and December 2015 diagnosed with OA/TOF...

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...

INTRODUCTION: This study reports our experience with open reconstructive surgery in patients with laryngotracheal stenosis (LTS) following prolonged intubation and/or tracheostomy in the context of COVID-19. METHODS: All patients underwent a preoperative endoscopic airway assessment. Posterior glottic lesions were graded according to the Bogdasarian classification, subglottic-tracheal lesions according to the Cotton-Myers classification and postoperative complications reported by the Clavien-Dindo classification...

OBJECTIVE: Tracheal resection (TR) and cricotracheal resection (CTR) are performed for patients with airway stenosis, tracheal tumor, and tracheoesophageal fistula. Post-operative complications include airway edema requiring reintubation, hematoma, anastomotic dehiscence, restenosis, and death. Although these complications and associated risk factors have been well described, the time where clinical suspicion should be highest post operatively has not been characterized. METHODS: Patients who underwent TR or CTR at a single center between 2015 and 2022 were reviewed...
