Complete transection of the bilateral main bronchus in a 5-year-old patient: a case report.

BACKGROUND: Tracheobronchial injuries caused by blunt chest trauma are rare in children, and such injuries usually involve multiple organs. Most cases involve respiratory failure on the way to the hospital, and the mortality rate is high. Herein, we describe the case of a 5-year-old patient who fell from an electric vehicle, causing complete rupture of the bilateral main bronchus. CASE PRESENTATION: We treated a 5-year-old patient with complete bilateral main bronchus rupture. Chest computed tomography (CT) failed to detect bronchial rupture. Continuous closed thoracic drainage resulted in a large amount of bubble overflow. Tracheal rupture was suspected. Fibreoptic bronchoscopy revealed complete rupture of the right main bronchus and rupture of the left main bronchus. Emergency tracheoplasty was performed under cardiopulmonary bypass (CPB). During the operation, we found that the bilateral main bronchi were completely ruptured. Postoperative recovery was smooth. The traditional surgical method for treating these injuries is lateral thoracotomy. However, a median sternotomy provides a better opportunity for selective repair. Extracorporeal circulation-assisted surgery is required for patients with unstable breathing. CONCLUSION: Complete fractures of the bilateral main bronchi are rare. Bronchial rupture should be suspected in the presence of expansion defect-dropped lungs and massive air leakage despite tube thoracostomy in haemopneumothorax developing after thoracic trauma. Extracorporeal circulation-assisted tracheoplasty is a relatively safe option for children whose respiratory system is difficult to maintain, thus ensuring oxygenation ventilation and a clear surgical field.

Slide tracheoplasty for congenital tracheal stenosis: A systematic review.

INTRODUCTION: Slide tracheoplasty has become the gold standard surgery for congenital tracheal stenosis (CTS). This condition is rare and the surgery can be challenging and is performed by experienced surgeons in tertiary centers. A few reports involving relatively small cohorts have been published. The aim of this review is to evaluate the post-operative mortality and morbidity of pediatric slide tracheoplasty for CTS. METHODS: A systematic literature review was performed according to PRISMA guidelines. The Medline and EMBASE databases were screened using a search strategy defined in collaboration with a librarian. We included articles reporting the post-operative mortality rate of slide tracheoplasties for treatment of CTS in children, when at least 10 patients were included. RESULTS: A total of 932 articles were reviewed, and 15 studies were eligible with a total of 845 patients. The overall post-operative mortality rate was 9.3 %, and most deaths were airway related. The open revision surgery rate after surgery was 2.8 % and the endoscopic revision rate was 27.6 %. DISCUSSION: This study highlights key factors to consider before the surgery and helps anticipate post-operative follow-up considerations for children with CTS. Several factors were identified as predictors of mortality including young age, weight at the time of surgery and association with lung hypoplasia or aplasia. CONCLUSION: Although slide tracheoplasty has gained popularity in recent years due to better outcomes, it remains a major surgery with mortality risk and the need for multidisciplinary management.

Impact of preoperative respiratory distress on outcomes of slide tracheoplasty.

OBJECTIVES: Children with congenital tracheal stenosis born in the developing world face a high risk of mortality due to limited access to proper treatment. Patients who required preoperative respiratory support were suspected to have poor survival after slide tracheoplasty; however, this was not clearly demonstrated in the previous studies. This study aims to investigate the impact of preoperative respiratory conditions on outcomes of slide tracheoplasty. METHODS: From 2016 to 2022, children who underwent slide tracheoplasty were retrospectively reviewed. Patients with respiratory distress requiring emergency operations (group A) were compared with patients in stable condition who were scheduled for surgery (group B). RESULTS: Perioperative results revealed that group A (n = 43) had a longer bypass time (P < 0.001), operation time (P = 0.01), postoperative ventilation time (P < 0.001) and length of intensive care unit stay (P = 0.00125) than group B (n = 60). The early mortality rate was 7.8%, and the actuarial 5-year survival rate was 85.3%. The cumulative incidence test revealed that group A was highly significant for overall mortality [sudistribution (SHR) 4.5; 95% confidence interval (CI) 1.23-16.4; P = 0.023]. Risk factors for overall mortality were prolonged postoperative ventilation time (hazard ratio 3.86; 95% CI 1.20-12.48; P = 0.024), bronchial stenosis (hazard ratio 5.77; 95% CI 1.72-19.31; P = 0.004), and preoperative tracheal mucositis (hazard ratio 5.67; 95% CI 1.51-21.31; P = 0.01). Four patients needed reintervention during a follow-up of 28.4 months (interquartile range 15.3-47.3). CONCLUSIONS: Preoperative respiratory distress negatively affected the outcomes of patients who required slide tracheoplasty. Therefore, early detection of congenital tracheal stenosis and aggressive slide tracheoplasty are crucial and obligatory to enhance long-term survival in this lethal congenital airway disease.

Creating Patient-Specific 3D-Printed Airway Models for Slide Tracheoplasty.

This protocol describes the method for creating 3D-printed trachea models for use in high-fidelity simulation-based training and advanced surgical planning for pediatric patients undergoing slide tracheoplasty. The goal is to provide a template and methodology to allow for replicability and more widespread dissemination of these models to improve clinical training and patient care. Laryngoscope, 2024.

Choice of suture technique may mitigate figure-of-8 deformity in slide tracheoplasty.

OBJECTIVES: To demonstrate varying degrees of immediate postoperative figure of 8 deformity following three different methods of tracheal suturing. STUDY DESIGN: Comparative ex-vivo study. METHODS: A fresh, unfixed rabbit trachea was harvested and bisected at its midpoint. The posterior membranous trachea was excised from both segments to mimic the anatomy of complete tracheal rings following longitudinal release. A slide tracheoplasty was performed on the same tracheal segments as an internal control, using three different methods of closure: simple running, running horizontal mattress, and a modified baseball stitch. Endoscopic and external photographs were taken immediately following repair to document the effect of closure technique on external and endoluminal anatomy. RESULTS: A simple running closure, in which traveling occurs between needle passes, showed the greatest degree of postoperative figure of 8 deformity. A running horizontal mattress suture closure showed less deformity and a modified running closure, in which traveling occurs within needle passes, showed the least deformity. CONCLUSIONS: Our study suggests that a minor modification of standard running closure techniques may help limit the common figure-of-8 deformity often noted following slide tracheoplasty. LAY SUMMARY: Figure of-8 deformity is a problem that can occur when repairing a narrow trachea referred to as tracheal stenosis. This deformity may be prevented using particular suture techniques which may decrease the likelihood that the trachea becomes blocked again following repair.

Innominate Artery Pseudoaneurysm Requiring Cartilage Tracheal Repair in a Child.

Mycotic aneurysms are rare but potentially catastrophic. We report a case of an innominate artery pseudoaneurysm in a 4-year-old patient that caused a tracheoinnominate fistula requiring tracheoplasty with a costal cartilage graft and a homograft iliac artery replacement of the diseased innominate artery, with a successful outcome.

Multidisciplinary Advanced Surgical Planning for Slide Tracheoplasty Using 3D-Printed Models.

OBJECTIVE: The objective of this study was to develop and assess multidisciplinary advanced surgical planning (ASP) sessions using three dimensional (3D) printed models for cervicothoracic slide tracheoplasty (CST). We hypothesized that these sessions would improve surgeon confidence, streamline intraoperative planning, and highlight the utility of 3D modeling. METHODS: 3D-printed patient-specific trachea models were used in pre-operative ASP sessions consisting of a multidisciplinary case discussion and hands-on slide tracheoplasty simulation. Participants completed a survey rating realism, utility, impact on the final surgical plan, and pre- and post-session confidence. Statistical analysis was performed via Wilcoxon and Kruskal-Wallis tests. RESULTS: Forty-eight surveys were collected across nine sessions and 27 different physicians. On a 5-point Likert scale, models were rated as "very realistic", "very useful" (both median of 4, IQR 3-4 and 4-5, respectively). Overall confidence increased by 1.4 points (+/- 0.7, p < 0.0001), with the largest change seen in those with minimal prior slide tracheoplasty experience (p = 0.005). Participants felt that the sessions "strongly" impacted their surgical plan or anticipated performance (median 4, IQR 4-5), regardless of training level or experience. CONCLUSION: 3D-printed patient-specific models were successfully implemented in ASP sessions for CST. Models were deemed very realistic and very useful by surgeons across multiple specialties and training levels. Surgical planning sessions also strongly impacted the final surgical plan and increased surgeon confidence for CST. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:3395-3401, 2024.

Regeneration Process of an Autologous Tissue-Engineered Trachea (aTET) in a Rat Patch Tracheoplasty Model.

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. We assigned twenty-seven rats to three groups according to the three types of patch grafts used: aTET patches (the aTET group), fresh tracheal autograft patches (the Ag group), or polylactic acid and polycaprolactone copolymer sheets (the PPc group). In each group, gross and histological evaluations were performed at 1 month (n = 3), 3 months (n = 3), and 6 months (n = 3) after implantation. We obtained high survival rates in all groups, but only the PPc group attained thick tracheal walls with granular tissues and no tracheal regeneration. On the other hand, the aTET and Ag groups reproducibly achieved complete tracheal regeneration in 6 months. So, an aTET could be a promising candidate for tracheal regeneration grafts.

Long- term outcomes of congenital tracheal stenosis after slide tracheoplasty.

PURPOSE: Long-term outcomes of slide tracheoplasty in patients with congenital tracheal stenosis (CTS) have rarely been reported. This study aimed to clarify the long-term outcomes of CTS after slide tracheoplasty. METHODS: The medical records of 33 patients who underwent slide tracheoplasty for CTS at our institution between January 2005 and July 2018, with a follow-up duration > 5 years, were retrospectively reviewed. Patients' characteristics, perioperative condition, operative management, postoperative course, tracheal stenosis rates and growth data, were collected from medical records. RESULTS: The median operative age, minimum tracheal diameter, length of stenosis, duration of hospital stays, and follow-up duration were 8 months, 2.4 mm, 35 mm, 39 days, and 90 months, respectively. One patient died of bleeding in the right lung at 126 months postoperatively. Among the 10 patients requiring postoperative tracheostomy, seven were successfully decannulated at a median of 65 months postoperatively. Tracheal stenosis rates improved postoperatively and were subsequently maintained. Growth impairment and psychomotor delay were observed in 9 and 16 patients, respectively with significant differences found only in cases with genetic abnormalities and not in tracheal stenosis severity. CONCLUSION: Slide tracheoplasty for CTS leads to favorable long-term outcomes. However, various associated anomalies may influence growth and psychomotor development, emphasizing the importance of adequate support.

Outcomes of not using tracheoplasty in asymptomatic tracheal stenosis found during open-heart surgery.

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. Patients who were diagnosed with a pulmonary artery or vascular sling or had moderate-to-severe respiratory symptoms before open-heart surgery were excluded. RESULTS: The median age and weight of the patients at operation were 3.0 months and 5.1 kg, respectively. They were categorized as those having tracheal stenosis on preoperative computed tomography (n = 12) or not having tracheal stenosis (n = 13). The narrowest diameter was significantly smaller in the former group (3.0 vs 5.8 mm, P < 0.05). The rates of reintubation and the tracheostomy, and intubation days tended to be higher in former group without statistical significance. Stenotic degree improved 2 months and 1 year or more after the operation (39.3% at operation, 28.4% at 2 months, 12.5% after 1 year). All patients were Ross class 1 or 2 at follow-up (mean, 7.1 years). CONCLUSIONS: Patients with tracheal stenosis showed tolerable long-term outcomes without using tracheoplasty. Accordingly, if tracheal stenosis, that would cause intubation difficulty, was incidentally revealed, concomitant tracheoplasty may not be required during open-heart surgery if the stenosis did not cause considerable symptoms or signs preoperatively.

Extramural recurrence of tracheal glomus tumour following resection by rigid bronchoscopy.

Glomus tumour of the trachea is very rare neoplasm that is generally benign and arises most commonly from the distal portion of the respiratory tree. This report presents the case of a 67-year-old man who was referred to our institute for excision of a tracheal mass that had been found incidentally, and subsequently recurred extramurally. Initial contrast-enhanced computed tomography images of the chest revealed a nodular lesion in the trachea, 2.5 cm above the carina, that demonstrated strong enhancement similar to blood vessels. The tumour was excised by rigid bronchoscopy, but an extramural tracheal lesion was detected 18 months later. Tracheal resection and end-to-end anastomosis were performed, and histopathological examination confirmed the extramural lesion as recurrence of the tracheal glomus tumour. The histologic features and treatment are discussed.

Nasal Septal Cartilage as Anterior Cap-Graft for Open Tracheoplasty in Cases for Laryngotracheal Stenosis: Our Initial Experience.

The aim of our study is to analyze the efficacy of nasal septal cartilage as cap-graft in laryngo-tracheoplasty in cases of Laryngotracheal stenosis. This was a prospective observational study carried out at a tertiary care hospital from March 2020 to March 2023. Total 8 patients who underwent laryngo-tracheoplasty using nasal septal cartilage as anterior Cap-graft were included in the study. Detailed history and clinical evaluation followed by diagnostic Flexible Fiber-optic Laryngoscopy and radiological investigations were done for all patients with post operative follow up for at least 1 year. Our study had maximum patients in age group of 11-30 years with male predominance, unknown compound ingestion being most common cause of intubation which was followed by tracheostomy. All patients had Cotton Mayer Grade III or IV subglottic stenosis. Out of 8 patients, 5 patients are decannulated, 1 patients still have T-tube in-situ whereas 2 patients didn't tolerate decannulation and required re-exploration. No donor site complication was seen during the study period. Nasal septal cartilage is a viable option for being used as anterior cap graft in laryngo-tracheoplasty. It can be a game changer, as can be done by E.N.T surgeon himself. No separate learning skills are required. It's cosmetically better with minimal complications; compared to life threatening complications like pneumothorax on using costal cartilage. Laryngeal framework is preserved as opposed to thyroid alar cartilage graft. Faster healing along with better postoperative donor site recovery are significant advantages.

[The role of bronchoscopy in slide tracheoplasty in children]. / 支气管镜在儿童Slide气管成形术中的应用.

OBJECTIVES: To study the role of bronchoscopy in slide tracheoplasty. METHODS: A retrospective analysis was conducted on the diagnosis and treatment of four children with tracheal stenosis admitted to Hunan Provincial People's Hospital from 2017 to 2020. The role of bronchoscopy was summarized in the preoperative evaluation, intraoperative positioning and measurement, and postoperative wound evaluation and treatment during slide tracheoplasty. RESULTS: Bronchoscopy evaluation before slide tracheoplasty showed that 3 of the 4 children had complete trachea rings, 2 had pulmonary artery sling, and 2 had multiple stenosis. Slide tracheoplasty was performed in the hospital on 3 children, and the midpoint of the stenosis segment was judged under bronchoscopy, and the length of the stenosis segment was measured, which assisted in the resection of the stenosis segment of the trachea. The pathogens were identified by lavage after the surgery. One child who developed scar traction 9 months after slide tracheoplasty in another hospital was improved by interventional treatment under bronchoscopy. Mucosal changes were found under bronchoscopy in 2 children 4 days after surgery, and the treatment plan was adjusted. One month after surgery, 2 children had granulation hyperplasia, which was improved by cryotherapy under bronchoscopy. One child abandoned treatment due to anastomotic necrosis and died. Three survivors were followed up for over 6 months with good prognosis, but all had tracheobronchial malacia. CONCLUSIONS: Bronchoscopy can be used for the management of slide tracheoplasty in children with tracheal stenosis, which is helpful to postoperative rehabilitation and follow-up.

Abstract: Introduction: The COVID-19 pandemic is a predominantly respiratory disease that has affected worldwide and has left more than 151 million cases, which usually require mechanical ventilation management with the intention of managing the upper airways for ventilation adequate oxygenation of people with COVID-19 and that reduces the risk of contagion for medical personnel. Objective: To describe the anesthetic approach for the induction and maintenance of a tracheoplasty derived from tracheal stenosis secondary to COVID-19. Material and methods: The description of a case and the guidelines that have been given for the management of tracheal stenosis are addressed. Conclusions: Timely anesthetic management and installation of a laryngeal splint is appropriate for the management of tracheal stenosis secondary to the process of prolonged mechanical intubation due to COVID-19.

Characteristics and Outcomes of Surgical Treatment for Bronchial Anomalies.

OBJECTIVES: Bronchial anomalies are rare but challenging conditions to treat in children, encompassing a variety of structural abnormalities that could compromise airway patency. This includes complete rings, absent cartilage, traumatic avulsions, bronchoesophageal fistulas, and cartilaginous sleeves. The objective of this study is to describe the characteristics and outcomes of a series of pediatric cases of bronchial anomalies that were treated by slide tracheobronchoplasty. METHODS: This is a single-institution retrospective case series of pediatric patients with bronchial anomalies who underwent surgical treatment between February 2004 and April 2020. Data extracted from electronic medical records included patient demographics, comorbidities, and surgical outcomes. RESULTS: There were a total of 29 patients included in the study, of which 14 had complete bronchial rings, 8 had absent bronchial rings, 4 had traumatic bronchial avulsions, 2 had bronchoesophageal fistulas, and one had a cartilaginous sleeve. Median follow-up time was 13 months (with a range of 0.5-213 months). The overall mortality rate was 17.2% (5 patients), all of whom had complete bronchial rings. Patients with complete bronchial rings also had a higher rate of not only cardiac (85.7%) and pulmonary comorbidities (85.7%) but also secondary airway lesions (78.6%). CONCLUSION: This is the largest series to date describing surgical treatment for bronchial anomalies. Complete bronchial rings were the most common anomaly treated, followed by absent rings and trauma. Surgical treatment can be successful but mortality rates are higher in patients with complete bronchial rings, possibly due to higher rates of pulmonary and cardiac comorbidities.

Use of Virtual Reality and Three-Dimensional Printing in the Surgical Planning of Slide Tracheoplasty.

Purpose: To describe our experience using virtual reality (VR) and three-dimensional (3D) printing as complements for the surgical planning process of slide tracheoplasty (ST) in patients with congenital tracheal stenosis (CTS). Description: VR and 3D printing are used for the surgical planning of ST as a therapeutic option in three female patients under five years of age with CTS. Evaluation: We assessed the planned surgical procedure, procedural time, postoperative complications, and outcomes, as well as the main surgeon's experience with the use of the applied technologies. Conclusions: The interaction within the VR environment allowed for collaboration of the surgical plan between surgical staff and enhancement of the radiologist-surgeon communication, while procedural simulation with 3D printing prototypes allowed for refining technical abilities for the surgical interventions. Based on our experience, the application of these technologies have added value to the surgical planning of ST and its outcomes in the treatment of CTS.

Impact of Tracheal Arborization and Lung Hypoplasia in Repair of Pulmonary Artery Sling in Combination With Long-Segment Tracheal Stenosis.

Background: Reimplantation of the left pulmonary artery (LPA) and slide tracheoplasty has been our standard approach of care for patients with pulmonary artery sling (PAS) and tracheal stenosis. We present our experience, with emphasis on tracheal arborization and hypoplastic lungs; and their impact on long-term outcome of children with PAS and tracheal stenosis. Methods: It is a retrospective comparative study. Data were classified and analyzed based on the type of tracheobronchial arborization and normal versus hypoplastic lungs. Results: Seventy-five children operated between January 1994 and December 2019 (67 with normal lungs and 8 with lung hypoplasia/agenesis) were included. Patients with hypoplastic lungs had higher rates of preoperative ventilation (87.5%), postoperative ventilation (10 vs 8 days, P = .621), and mortality (50% vs 9%, P = .009) compared with those with normal lungs. Nineteen patients had tracheal bronchus (TB) variety and 30 patients had congenital long-segment tracheal stenosis (CLSTS) variety of tracheobronchial arborization. Endoscopic intervention was needed in 47.4% of patients with TB type and 60% with CLSTS type. CLSTS patients had higher rates of preoperative ventilation (60% vs 47.4%, P = .386), longer periods of postoperative ventilation (13 vs 6.5 days, P = .006), and ICU stay (15 vs 11 days, P = .714) compared with TB type. Conclusion: Surgical repair of PAS with tracheal stenosis has good long-term outcomes. All variations of tracheal anatomy can be managed with slide tracheoplasty. Persistence of airway problems requires intervention during follow-up as tracheal stenosis continues to be the Achilles heel.

Tracheal reconstruction surgery for congenital tracheal stenosis.

PURPOSE: Congenital tracheal stenosis is a rare but dangerous disease. Reconstructive tracheal surgery is a life-saving treatment but also a challenging procedure. This study aims to evaluate the outcomes of tracheal reconstruction surgery. METHODS: A prospective cohort study was conducted with all the records of congenital tracheal stenosis which had been managed by tracheal reconstruction surgery at Children's Hospital 2 Ho Chi Minh City from August 2013 to August 2022. RESULTS: Sixty-seven cases, who underwent slide tracheoplasty, were included in our study. Mean age was 7.6 months (25 days - 8 years). Common congenital-associated lesion was left pulmonary artery sling, accounting for 65.7% of cases. Bronchial stenosis was found in 22.4% patients. Emergency surgery was performed in eight cases. The survival rate in this review was 86.6%. Nine patients died in which four of nine cases (44.4%) were emergency surgery. The recurrent stenosis rate was 8.9%, only two cases needed reoperation in which one died and one recovered uneventfully. The outcomes of surgery were good in 53 cases (79.1%). CONCLUSION: Tracheal reconstruction surgery with slide tracheoplasty technique is safe and versatile technique which is feasible in every case of congenital tracheal stenosis. Mortality was associated with severe cases which required emergency surgery.

Sliding tracheoplasty of complete tracheal cartilage rings in children.

INTRODUCTION: Complete tracheal rings are a rare malformation that occurs in 1 out of 100,000 live births. It is rare, isolated tracheal or tracheobronchial anomaly developed due to abnormal cartilage growth with formation of complete ring and often resulting in airway stenosis. Slide tracheoplasty, as it was originally described by Tsang et al. and popularized by Grillo et al., overlaps stenotic segments of trachea, shortening trachea itself, thus, doubling the circumference and diameter of the stenotic area. MATERIALS AND METHODS: We have performed slide tracheoplasty in 12 children during the period of 2019-2021 in thoracic surgery department of our center. Median age was 15 ± 21,1 months (2 months-6 years),median weight - 8,04 ± 4,75 kg (3-20,7 kg),tracheal lumen varied from 2.5 to 3.0 mm, stenosis length - from 40 to 70% of the trachea length. RESULTS: Slide tracheoplasty was performed using central veno-arterial extracorporeal membrane oxygenation in 7 cases and using cardiopulmonary bypass in 5 cases. Concomitant heart disease was revealed in 5 children (pulmonary artery sling in 3 cases, ventricular septal defects - 1, aberrant subclavian artery -1). 5 children underwent one-stage correction of VSD: plastic VSD -1; left pulmonary artery reimplantation - 3; subclavian artery reimplantation - 1. All patients were on mechanical ventilation for 4,3 ± 2,78 days at postoperative period. Patients were discharged 16,3 ± 5,14 days after surgery. Satisfactory result of treatment in the form of respiratory failure relief was achieved in 10 patients. It was possible to increase the trachea lumen from 1.5 to 2 times in all cases. There were 2 (16,6%) fatal cases due to sepsis and multi-organ failure development. CONCLUSIONS: Children with complete tracheal rings are very complicated patients with various comorbidities. Despite the advances in medicine, sometimes it is impossible to save lives of these children. The use of extracorporeal circulation (ECMO and bypass) allows us to safely perform reconstructive surgery on the trachea and save the child from respiratory failure manifestations. If needed, simultaneous correction of heart and tracheal defects is possible. Slide tracheoplasty allows to increase trachea lumen at least in 1.5-2 times. Mechanical ventilation is an unfavorable predictive factor for the outcomes of congenital tracheal stenosis management. LEVEL OF EVIDENCE: III.

Postoperative nursing care of a child with pulmonary artery displacement combined with slide tracheobronchial plasty.

Generally, pulmonary artery sling operation involves the pulmonary artery transplantation to be cut off. Nursing care is focused on the postoperative pulmonary vascular anastomosis, respiratory tract, and blood pressure after surgery. We report the case of an infant who underwent pulmonary artery tracheal transposition combined with Slide keratoplasty, where the pulmonary artery transplantation was not cut off. We highlight that postoperative pulmonary artery blood flow to the unobstructed airway and airway reconstruction surgery should be focused on to help children recover and ensure successful surgery. This case study reports the postoperative nursing experience of one patient with pulmonary artery sling undergoing pulmonary tracheal transposition combined with Slide arthroplasty. This demonstrates that throughout the postoperative care, airway management should be focused on to maintain circulation stability in the early postoperative period, and corresponding measures such as posture management, atomization inhalation, and improved chest physical therapy should be applied according to the special surgical method of the case in order to reduce airway complications and to improve the surgical success rate of children with pulmonary artery sling undergoing pulmonary tracheal transposition combined with Slide arthroplasty. In similar cases, after pulmonary tracheal transposition and Slide angioplasty, the doctors and nurses should pay attention to early circulation stability and focus on airway management through careful treatment and nursing, so as to promote the child's recovery.
