Slide tracheoplasty for congenital tracheal stenosis with involvement of the carina and bronchi: a case report.

A female newborn presented with respiratory distress at birth and was diagnosed with congenital tracheal stenosis. The stenosis was positioned at the distal trachea and compromised the carina and the right and left bronchi. She underwent surgical treatment using circulatory life support with veno-arterial peripheral extracorporeal membrane oxygenation, and the airway was reconstructed using the slide tracheoplasty technique to build a neocarina. The patient had an excellent postoperative course, was successfully weaned from extracorporeal membrane oxygenation and invasive ventilation, and was discharged.

Tracheobronchial abnormalities on computed tomography angiography in children with congenital heart disease.

OBJECTIVES: To evaluate the assortment of tracheobronchial abnormalities on computed tomography angiography (CTA) in children with congenital heart disease (CHD). METHODS: In this study approved by the Institute ethics committee, CTA studies of 182 children (age range: 2 days-8 years) with CHD, performed from July 2021 to March 2023 were analyzed. Two pediatric radiologists independently assessed the tracheobronchial airways (from the trachea to lobar bronchi) for developmental and branching anomalies and airway compromise (narrowing). In cases which demonstrated airway compromise, the extent and the cause of airway narrowing were evaluated, and the etiology were divided into extrinsic and intrinsic causes. Interobserver agreement between the two radiologists was calculated using kappa statistics. RESULTS: One hundred children demonstrated normal airway anatomy and no luminal narrowing. Airway narrowing was observed in 63 (34.6%) children (κ: 0.954), and developmental airway anomalies were seen in 32 (17.5%) children (κ: 0.935). Of the 63 children with airway narrowing, 47 (25.8%) children had extrinsic cause for narrowing, 11 (6%) children had intrinsic causes for narrowing, and 5 (2.7%) children had both intrinsic and extrinsic causes attributing to airway compromise. Significant airway narrowing (>50% reduction) was seen in 35 (19.2%) children (κ: 0.945). CONCLUSION: Tracheobronchial airway abnormalities are frequently associated in children with CHD and need to be appraised preoperatively. Cross-sectional imaging with CTA provides excellent information on tracheobronchial airway anatomy and caliber as well as delineates the possible etiology of airway narrowing, thus accurately diagnosing airway anomalies.

Esophageal lung complicated by recurrent pneumonia.

A 6-month-old infant with recurrent respiratory infections, rapid breathing, and reduced air entry on the right side was diagnosed with congenital bronchopulmonary foregut malformation (CBPFM). Imaging revealed a collapsed and underdeveloped right lung, with the right bronchus appearing to originate from the lower part of the esophagus. An esophagogram confirmed the diagnosis by showing contrast flowing freely from the lower esophagus to the right bronchus.

Computed tomography findings of communicating bronchopulmonary foregut malformation: a retrospective study of 18 patients.

BACKGROUND: Communicating bronchopulmonary foregut malformation is a rare anomaly characterized by a patent congenital communication between the esophagus or stomach and an isolated portion of the respiratory system. An esophagogram is taken as the gold standard for diagnosis. Compared with esophagography, computed tomography (CT) is more widely used and easily obtained, but CT findings have been described as nonspecific. PURPOSE: To describe CT findings in 18 patients with communicating bronchopulmonary foregut malformation to assist with early diagnosis. MATERIAL AND METHODS: A retrospective review of 18 patients who had proven communicating bronchopulmonary foregut malformation between January 2006 and December 2021 was conducted. For each patient, the medical records, including demographics, clinical manifestations, upper gastrointestinal radiography, magnetic resonance imaging and CT findings, were reviewed. RESULTS: Among the 18 patients, there were 8 males. The right to left ratio was 3.5:1. An entire lung was involved in 10 patients, a lobe or a segment was involved in 7 patients and an ectopic lesion was located in the right neck in 1 patient. The isolated lung may arise from the upper esophagus, mid-esophagus, lower esophagus or stomach, which were detected in 1, 3, 13, and 1 patient, respectively. On chest CT, an extra bronchus which did not arise from the trachea was detected in 14 patients. Contrast-enhanced chest CT was performed in 17 patients, the isolated lung receiving its blood supply from the pulmonary artery in 13 patients, the systemic artery in 11 patients and both pulmonary and systemic arteries in 7 patients. CONCLUSIONS: The presence of an extra bronchus, which does not arise from the trachea, highly suggests the diagnosis of communicating bronchopulmonary foregut malformation. Contrast-enhanced chest CT can provide accurate information regarding the airways, lung parenchyma and vascular structures that is useful to plan surgery.

Tracheal Bronchus Detected During General Anesthesia: A Case Report.

A tracheal bronchus is a congenital abnormality of the tracheobronchial tree in which a displaced or accessory bronchus arises from the trachea superior to its bifurcation. We herein report a case in which a tracheal bronchus was incidentally found after induction of general anesthesia, and we discuss the potential airway management problems that may have ensued. An 80-year-old man was scheduled for buccal mucosa resection and abdominal skin grafting for treatment of squamous cell carcinoma of the left buccal mucosa. Because of trismus and anticipated airway difficulty, an awake intubation was performed under sedation. A 3-branched structure was incidentally observed at the first branching site that was supposed to be the carina. The tip of the endotracheal tube was repositioned 3 cm above the tracheal trifurcation, and the rest of the procedure proceeded uneventfully. A flexible fiberoptic scope is not used in many anesthesia cases, making the identification of such tracheal or bronchial abnormalities more difficult. Therefore, it is important to carefully check the bronchial morphology on any available chest radiographs before surgery, listen to lung sounds after intubation, and assess thoracic lung compliance without neglecting routine safety checks.

Successful surgical treatment of congenital tracheal stenosis combined with tracheal bronchus and left pulmonary artery sling: a 10-year single-institution experience.

PURPOSE: Radical surgery for congenital tracheal stenosis (CTS) is technically demanding. CTS combined with tracheal bronchus (TB) and pulmonary artery (PA) sling is a particularly challenging condition. We herein report our successfully modified surgical techniques for CTS combined with TB and PA sling. METHODS: Nine patients treated at our institution from July 2010 to December 2020 for CTS with TB and PA sling were enrolled. The patients' characteristics, operative results, and clinical outcomes were reviewed and analyzed retrospectively. RESULTS: The mean age at the operation and body weight were 8.0 ± 4.4 months old and 6.5 ± 0.8 kg, respectively. The mean tracheal diameter and length of the stenotic lesion were 3.2 ± 1.0 mm (mean stenosis rate 46.2%) and 25.4 ± 4.9 mm, respectively. All cases were complicated with PA sling at bifurcation stenosis with tracheobronchomalacia. All patients underwent modified posterior-anterior slide tracheoplasty with an inverted Y-shaped incision at the bifurcation and repositioning of the PA. The mean postoperative intubation period was 25.0 ± 32.1 days. There were no major intraoperative or postoperative complications, including hypoxic-ischemic encephalopathy. The mean hospital stay was 92.2 ± 73.4 days. All patients were discharged home without tracheostomy or oxygen support. CONCLUSION: Our slide tracheoplasty technique for CTS with TB and PA sling achieved excellent outcomes. LEVEL OF EVIDENCE: Level IV.

Tracheal bronchus: a rare cause of recurrent pneumonia in adults.

Tracheal bronchus, also known as bronchus suis, is a rare congenital anomaly of the airway where an accessory bronchus originates directly from the trachea. With an estimated incidence of 0.001%-2.0%, this condition is rarely reported in literature. It is usually discovered as an incidental finding in an otherwise asymptomatic individual. However, it can act as a focus of recurrent infection or present as persistent radiographic infiltrates. Multidetector CT imaging and bronchoscopy play a crucial role in the identification of this entity. We hereby report the case of a middle-aged man who presented with recurrent right upper lobe pneumonia, which was found to be due to an underlying tracheal bronchus.

Asociación del complejo ring-sling con pig bronchus: a propósito de un caso pediátrico / Ring-sling complex association with pig bronchus: a pediatric case report

El complejo ring-sling es una asociación entre el sling de la arteria pulmonar y la estenosis traqueal congénita por anillos traqueales completos. El sling de la arteria pulmonar es una forma rara de anillo vascular dentro de las cardiopatías congénitas. Se presenta el caso clínico de un niño con estridor laríngeo asociado a dificultad respiratoria evaluado en otro centro, donde se realizó endoscopia respiratoria y se observó compresión traqueal extrínseca. Ante la sospecha clínica de anillo vascular, se solicitó angiotomografía computada (angioTC) y se confirmó diagnóstico de sling de arteria pulmonar. Fue derivado a nuestro hospital y durante la intervención quirúrgica se realizó nueva endoscopia respiratoria y traqueobroncografía. Se llegó al diagnóstico de estenosis traqueal congénita con bronquio derecho accesorio (pig bronchus) y anillos vasculares completos, ambos reparados en el mismo acto quirúrgico.

The ring-sling complex is an association between pulmonary artery sling and congenital tracheal stenosis. Pulmonary artery sling is a rare form of vascular ring in congenital heart disease. The clinical case of a child with inspiratory laryngeal stridor associated with respiratory distress is presented, evaluated in another center where respiratory endoscopy was performed, observing extrinsic tracheal compression. Given the clinical suspicion of a vascular ring, CT angiography was requested, confirming the diagnosis of pulmonary artery sling. He was referred to our hospital and during the surgical intervention a new respiratory endoscopy and tracheobronchography were performed, reaching the diagnosis of congenital tracheal stenosis, right accessory bronchus (pig bronchus) and complete vascular rings, both repaired in the same surgical act.

Reversible bronchiectasis caused by influenza virus mimicking Williams-Campbell syndrome.

The term bronchiectasis refers to permanent enlargement of the bronchi. It is increasingly diagnosed because of high-resolution computed investigations. It can be congenital or acquired, the latter mostly following infection. Williams-Campbell syndrome is a rare form of congenital non-cystic fibrosis bronchiectasis. Here we report a 5-month-old girl with reversible bronchiectasis treated with extracorporeal membrane oxygenation for acute respiratory distress syndrome (ARDS) caused by influenza virus following surgery for congenital heart disease. Chest CT showed an abnormally large bronchial tree mimicking Williams-Campbell syndrome. At 9 months later, chest CT showed regression of bronchiectasis and normalized caliber of previously collapsed segments in both lungs. This atypical course illustrates that influenza virus can cause reversible bronchiectasis in infants and mimic congenital disease such as Williams-Campbell syndrome.

[Resection of Left Upper Division by Uniportal Video-assisted Thoracoscopic Surgery for Congenital Bronchial Atresia:Report of a Case].

We report a case of congenital bronchial atresia resected by the uniportal thoracoscopic approach. A man in his 20s with congenital bronchial atresia diagnosed at 16 years of age visited our hospital with gradually worsening shortness of breath. Chest computed tomography revealed a localized emphysematous area that progressively increased in size, in the left upper lobe and the absence of a left upper division bronchus with mucoid impaction. Surgical treatment was deemed necessary in view of dyspnea and progressively worsening emphysema, and the resection of left upper division was performed by uniportal video-assisted thoracoscopic surgery.

Bronquio cardíaco diagnosticado por estudio endoscópico / Cardiac bronchus diagnosed by endoscopic study

Introducción: El bronquio cardíaco es una anomalía congénita poco frecuente, con una incidencia de aproximadamente 0,1 por ciento. Consiste en un bronquio supernumerario que nace de la pared medial del bronquio principal derecho o del bronquio intermediario, opuesto al origen del bronquio para el lóbulo superior derecho y proximal al bronquio del segmento apical del lóbulo inferior derecho. Objetivo: Presentar el caso de un bronquio cardíaco diagnosticado por estudio endoscópico. Presentación del caso: Se presenta el caso de un paciente que ingresa en el servicio de Neumología del Hospital Clínico Quirúrgico Hermanos Ameijeiras por presentar tos, expectoración blanca, disnea a los grandes esfuerzos y una radiografía de tórax con una radiopacidad en el lóbulo superior izquierdo y que como hallazgo incidental durante la realización de la broncoscopia se detecta un bronquio cardíaco o supernumerario. Conclusiones: El bronquio cardíaco es una malformación congénita infrecuente que puede cursar de manera asintomática, cuyo diagnóstico definitivo es por broncoscopia(AU)

Introduction: The cardiac bronchus is a rare congenital anomaly, with an incidence of approximately 0.1 percent. It consists of a supernumerary bronchus that arises from the medial wall of the right main bronchus or the bronchus intermediary, opposite the origin of the bronchus for the right upper lobe and proximal to the bronchus of the apical segment of the right lower lobe. Objective: To report the case of a cardiac bronchus diagnosed by endoscopic study. Case report: We report the case of a patient who was admitted to the Pneumology service at Hermanos Ameijeiras Surgical Clinical Hospital due to cough, white expectoration, dyspnea on exertion and a chest X-ray with radiopacity in the upper lobe, and that as an incidental finding during the bronchoscopy, a cardiac or supernumerary bronchus was detected. Conclusions: Bronchus is an infrequent congenital malformation that can be asymptomatic, whose definitive diagnosis is by bronchoscopy(AU)

A 50-Year Old Woman With Recurrent Right-Sided Chest Pain.

CASE PRESENTATION: A 50-year-old woman was seen in the office for recurrent episodes of cough and right-sided chest pain. She had visited the ED three times in the past 15 months for the same complaint. Each time, the pain started gradually affecting the right lateral chest wall. It was pleuritic and was associated with cough and mild shortness of breath. During these episodes, she reported low-grade fever but denied any night sweats, chills, sputum production, wheezing, or hemoptysis. She was treated with antibiotics and systemic steroids with resolution of her symptoms. The patient was an active smoker with a more than 35-pack year history. She had no known medical condition and was not taking any medication routinely at home. She had no family history of alpha-1 antitrypsin deficiency or Marfan syndrome.

Oblique Carinal End-to-end Anastomosis for Pig Bronchus in Organ Donor and Lung Transplant Recipient.

Pig bronchi are rare anomalies in which the right upper lobe bronchus originates above the carina. During surgery this can lead to technical challenges associated with the bronchial anastomosis, especially during lung transplantation. We herein report the case of a combined liver-lung transplantation with a pig bronchus in both the organ donor and transplant recipient. In both cases the bronchi originated slightly above the level of the carina facilitating an oblique resection and a single tracheobronchial anastomosis with a running suture. Follow-up bronchoscopy showed a completely healed anastomosis with no evidence of malacia or stenosis.

Congenital anomalies of the large intrathoracic airways.

Congenital lung lesions are numerous but rare in individual clinical practice. They do require close multidisciplinary collaboration between health care professionals. This educational review will focus on the pathophysiology, clinical manifestations, surgical approaches, and anesthetic management of congenital anomalies of the large intrathoracic airways: congenital tracheal stenosis, tracheal agenesis, tracheal diverticulum, bronchial anomalies (tracheal, esophageal, or bridging bronchus), congenital lung malformations, lung sequestrations and Scimitar syndrome, lobar emphysema, Williams-Campbell syndrome, and pleuropulmonary blastoma. In addition, this review will illustrate common pitfalls and challenges related to the anesthesia management with emphasis on ventilation and correct endotracheal tube positioning.

Tracheoplasty for Congenital Tracheal Stenosis with Bilateral Tracheal Bronchus.

INTRODUCTION: Congenital tracheal stenosis (CTS) with a bilateral tracheal bronchus (TB) has not been reported as a subtype of CTS. A novel technique to manage CTS in patients with a bilateral TB is described. CASE REPORT: An infant with tetralogy of Fallot underwent repair of cardiac anomaly at age 1 month. He experienced numerous cyanosis and episodes of transient respiratory arrest. Chest computed tomography (CT) demonstrated an aberrant bilateral upper lobe bronchus arising directly from the trachea and a stenotic trachea connecting the pseudo- carina to the true carina between the common right lower and left lower bronchus. On bronchoscopy, the diameter of the lumen of the narrowed segment was estimated to be less than 2 mm. Tracheal reconstruction was undertaken when he was 2 years of age. The surgical technique using a modified slide tracheoplasty for the correction of this anomaly are described. After surgery, the patient was extubated and has had no respiratory symptoms. DISCUSSION AND CONCLUSION: The patient had unique anatomic considerations that made reconstruction challenging. Our technique of covering a stenotic section by normal trachea is a modification of the slide tracheoplasty technique and is useful for CTS with a unilateral and a bilateral TB.

[Management of unilateral acquired pulmonary bullous emphysema in a premature infant through selective bronchial intubation. Case report and review of literature]. / Manejo de enfisema intersticial unilateral adquirido en un recién nacido prematuro mediante intubación bronquial selectiva: Descripción de un caso y revisión de la literatura.

INTRODUCTION: Acquired pulmonary bullous emphysema is an infrequent complication of assisted ventilation in the premature infant that is difficult to manage. OBJECTIVE: The goal of this report is to present the case of a premature infant who required selective bronchial intubation as well as to provide a review of the current literature on the subject. CLINICAL CASE: The patient is a 27-week gestational age neonatal female patient whose clinical course was complicated by left unilateral bullous emphysema during assisted ventilation for respiratory distress syndrome. Lower peak inspiratory pressures, higher res piratory frequencies, patient positioning, and lower inspiration time failed to improve the patient's condition. The left lung became critically overinflated and compressed the right lung to the point of atelectasis. The patient was selectively mono intubated through the right main bronchus, which resulted in a collapse of the left emphysematous lung. Single right lung ventilation was continued for 48 hours before restarting conventional ventilation of both lungs. Our patient improved significantly, was extubated 6 days after the procedure and later discharged home with normal chest x-ray images. CONCLUSION: Selective bronchial intubation is a safe and effective procedure in cases of acquired bu llous emphysema when usual ventilatory management fails.

Right apical-posterior segmentectomy with abnormal anterior segmental bronchus and artery: a case report.

BACKGROUND: Displaced anterior segmental bronchus and pulmonary artery is extremely rare. A keen knowledge of such variations is required in the field of pulmonary segmentectomy, for unawareness of the structural variation could lead to intra- and postoperative complications. CASE PRESENTATION: A 50-year-old female presented to our department with suspected lung adenocarcinoma. Preoperative 3-dimensional computed tomographic bronchography and angiography revealed anterior segmental bronchus and anterior segmental pulmonary artery variation: the anterior segmental bronchus derived from the middle lobe bronchus, accompanied by a distally distributed anterior segmental pulmonary artery branch. A right apical-posterior segmentectomy using inflation-deflation technique was performed successfully. CONCLUSIONS: The keen observation and proper application of modern imaging technology and operative technique could greatly aid segmentectomy, preventing intra- and postoperative complications from happening.
