Bronchial stenosis

CONTEXT: Laryngo-tracheal stenosis (LTS) is a relatively rare disease, and conventional methods have difficulty achieving one-lung ventilation (OLV) when an anatomical abnormality exists. Selecting an appropriate method for patients with LTS can ensure oxygenation, collapse the lung, and reduce damage. OBJECTIVE: The study intended to perform a comprehensive review of the literature and a systematic review to examine the characteristics and management of OLV for LTS patients...

Left aortic arch with right descending aorta associated with coarctation of the aorta is a rare congenital cardiac anomaly. Conventional aortic arch repair in this condition may cause airway compression by the abnormally coursing descending aorta. We present the case of a neonate with this anomaly who underwent successful descending aortic translocation to prevent postoperative left main bronchial stenosis.

It is not widely recognized that iron (ferrous sulfate) pill aspiration causes airway damage. Clinical diagnosis is challenging because patients are often unaware that they have aspirated a pill. The literature on this entity consists mainly of case reports. The aim of this study is to describe the clinical and pathologic features of iron pill aspiration in a series of 11 patients. A retrospective review of our pathology archives was performed to identify cases of iron pill aspiration (2013-23). All available histologic and cytologic material was re-reviewed...

Coinfection of pulmonary mucormycosis and tuberculosis is a rare and challenging condition, particularly in immunocompromised patients. We present the case of a 60-year-old woman with poorly controlled diabetes mellitus who developed dysphonia, persistent cough, and expectoration. Imaging studies revealed a cavitary lesion and a mass in the left lung, along with stenosis of the left main bronchus. A bronchoscopy confirmed the presence of a bronchomediastinal fistula with pus discharge. Polymerase chain reaction testing of bronchial secretions revealed a co-infection of tuberculosis and mucormycosis...

Pulmonary artery sling in adults is a rare congenital vascular malformation usually accompanied by tracheal and bronchial stenosis. Due to its high mortality risk and relatively poor prognosis, it has rarely been reported in adults. We reported a middle-aged patient who presented with shortness of breath, predominantly after activity, since childhood. He was diagnosed with "tracheal stenosis" in another hospital and received symptomatic treatment. The diagnosis of left pulmonary artery sling with congenital tracheal stenosis was confirmed by multi-slice spiral CT (MSCT), airway examination with flexible bronchoscope and 3D image post-processing system...

A man in his 70s in a rehabilitation hospital, post cerebral infarct, became acutely short of breath with reduced oxygen saturations and an elevated d-dimer.Non-occlusive filling defects were noted on the CT pulmonary angiogram in the proximal left pulmonary arteries. There was associated hypoplasia of the distal pulmonary arterial tree in the left hemithorax with left pulmonary vein stenosis. Review of previous imaging suggested this oligaemia was longstanding.Although filling defects in the pulmonary arteries usually correspond to embolic material, in our patient they were too dense to represent thrombus and probably represented flow-related artefacts in the setting of chronic air trapping...

BACKGROUND: Tracheobronchomalacia (TBM) and airway stenosis are recognized etiologies of airway obstruction among children. Their management is often challenging, requiring multiple interventions and prolonged respiratory support with associated long-term morbidity. Metallic or silicone stents have been used with mixed success and high complication rates. More recently biodegradable Ella stents (BES) provided an attractive interventional option. OBJECTIVES: We report our experience in the treatment of TBM and vascular airway compression using BES...

PURPOSE: This study aimed to investigate the safety and efficacy of transarterial infusion chemotherapy for the treatment of esophageal cancer with airway stenosis. METHODS: Data of patients with advanced esophageal cancer complicated with airway stenosis treated with transarterial infusion chemotherapy were retrospectively analyzed. Dyspnea, clinical efficacy and adverse reactions were evaluated. RESULTS: Of these patients, 27 had grade II preoperative dyspnea, and 31 had grade III preoperative dyspnea, 26 had grade I postoperative dyspnea, 25 had grade II postoperative dyspnea, and 7 had grade III postoperative dyspnea...

Objective: To explore the characteristics of pulmonary blood flow perfusion imaging of single photo emission computer tomography/computer tomography (SPECT/CT) in chronic pulmonary vascular Stenosis (CPVS) caused by different etiological factors. Methods: This is a retropective study. Present study screened 50 consecutive cases diagnosed with chronic pulmonary vascular stenosis from January 2019 to January 2020 in the department of cardiology of Gansu Provincial Hospital and underwent SPECT/CT pulmonary blood flow perfusion examination...

BACKGROUND: In peripheral lung tumours, stereotactic body radiotherapy (SBRT) is superior to conventional RT. SBRT has also shown high loco-regional control (LC) in centrally located tumours, but there is a high risk of severe toxicity. The STRICTSTARLung trial (NCT05354596) examines if risk-adapted SBRT for central tumours is feasible. In this study, we examined overall survival (OS), Disease-free survival (DSF), LC, and toxicity in patients with central tumours that could have been candidates for SBRT but received conventional RT...

BACKGROUND: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of disorders characterized by necrotizing inflammation of small- and medium-sized blood vessels and the presence of circulating ANCA. Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic ANCA-associated vasculitis, characterized by peripheral eosinophilia, neuropathy, palpable purpuras or petechiae, renal and cardiac involvement, sinusitis, asthma, and transient pulmonary infiltrates...

41-year-old lady, known case of Takayasu arteritis with pulmonary arterial involvement, presented with multiple episodes of haemoptysis (maximum 50 mL) in a week. She had undergone descending thoracic aorta angioplasty and stenting 3 years ago due to uncontrolled hypertension, left ventricular systolic dysfunction and approximately 70% stenosis of descending thoracic aorta. This lady was treated with embolization of hypertrophied bronchial artery as well as left internal mammary artery branch for management of haemoptysis...

Tracheobronchial stenosis (TBS) in adults derives from congenital and acquired conditions, including prolonged mechanical intubation, expiratory central airway collapse, infectious or inflammatory disease, and malignancy. The most common clinical presentation is shortness of breath, recurrent infections, and chronic cough. TBS is usually diagnosed via computed tomography or bronchoscopy, with the latter doubling as a therapeutic tool. We present a case of an atypical fibrotic bridge connecting the walls of the distal trachea and fibrotic bronchial stenosis treated with electrocautery knife and balloon dilation, in an adult patient with bronchopulmonary dysplasia...

Ultracentral (UC) lung lesions are generally defined by the presence of the tumour or the Planning Target Volume (PTV) abutting proximal bronchial tree (PBT) or the esophagus. Initial reports rose awareness regarding the potential toxicity of stereotactic body radiotherapy (SBRT) when delivered to UC lesions. Major concerns include necrosis, stenosis, and bleeding of the PBT. Technological improvements now enable the delivery of more accurate treatments, possibly redefining the historical "no-fly zone". In this review, studies focusing on the treatment of UC lesions with SBRT are presented...

An 82-year-old female patient with severe aortic stenosis underwent aortic valve replacement. After weaning from cardiopulmonary bypass, it was noticed that Swan-Ganz( SG) catheter tip was located 50 cm distally to the right neck. After the catheter was pulled back, massive hemoptysis occurred. Fiberoptic bronchoscopy revealed bleeding from the left main bronchus. The tracheal tube was exchanged to a left selective bronchial tube and protamine sulfate was administered. However, massive hemorrhage continued...

Endobronchial tuberculosis often causes bronchial stenosis. Balloon dilation is a minimally invasive and effective bronchoscopic intervention for bronchial stenosis; however, reports on balloon dilation in older individuals are limited. We present a case of a 77-year-old woman with endobronchial tuberculosis and clarify the efficacy and safety of balloon dilation. She presented with dyspnea, right lung atelectasis, and respiratory failure 55 days after initiation of antituberculosis therapy. We performed bronchoscopic balloon dilatation for the right main bronchial stenosis...

Although the WHO has declared the end of the pandemic emergency, COVID-19 still poses a threat to immunocompromised patients. The COVID-19 pandemic has spread throughout the world over the last two years, causing a significant number of deaths. After three years, SARS-CoV-2 has lost its initial lethality but has shown a significantly worse prognosis for immunocompromised patients, especially those who have undergone lung transplantation, compared with the general population. This paper presents two compelling case studies that highlight the complex challenges of COVID-19 infection in lung transplant recipients...
