Congenital tracheal stenosis.

Twenty-one cases of congenital tracheal stenosis seen at the Royal Alexandra Hospital for Children 1971 through 1980 were reviewed with regard to the clinical features, associated anomalies, endoscopic findings and radiological evaluation. Congenital tracheal stenosis was usually a serious problem often associated with other major anomalies of the respiratory tract, esophagus, or skeleton. There was no set pattern of presentation. The presenting features included: persistent wheeze or stridor, atypical "respiratory distress," and atypical "croup" or "bronchiolitis." Documentation of the nature and extent of the stenosis by endoscopy and, if necessary, tracheobronchogram was important for prognosis and to direct treatment. Congenital tracheal stenosis must be considered in infants who present with atypical respiratory tract obstruction, especially where there is an H-type tracheoesophageal fistula, pulmonary hypoplasia or skeletal abnormalities such as hemivertebrae or a thumb abnormality.

Successful management of congenital tracheal stenosis in infancy.

Seven infants with congenital tracheal stenosis were evaluated and treated to assess the efficacy of current techniques of management. All had multiple congenital anomalies in addition to tracheal stenosis. Notably, three infants had imperforate anus and three had vascular rings. Each infant presented early with respiratory distress. While bronchoscopy and/or bronchography were performed in some, the diagnosis could be made from high contrast x-rays of the chest in each instance. The complexity of the tracheal lesion(s) determined the operative approach. Complicating factors included tracheomalacia, multiple stenoses, pulmonary hypoplasia, and carinal involvement. The trachea was approached through an anterolateral thoracotomy in five cases and through the neck in one. Cardiopulmonary bypass was never required. Simple resection was possible only once. Four patients received costal cartilage grafts, and one graft was created from dura. Grafts varied from 2 1/2 to 6 cm in length and extended onto the bronchi in two cases. All patients with grafts were treated with postoperative endotracheal stents and ventilatory assistance and all were extubated successfully. One patient had trisomy 16p+ detected after successful extubation and died later. One patient was treated expectantly and died. While each case must be individualized, repair of complex tracheal stenosis often results in dramatic immediate improvement and long-term success.

Endoscopic laser repair of posterior glottic, subglottic and tracheal stenosis by division or micro-trapdoor flap.

Laryngeal and tracheal stenosis have been refractory to a wide variety of treatments including dilation, stents, or have required major open operation, e.g., laryngofissure with and without skin or mucosal grafts and segmental resection with larynx release. Adequate airway even when achieved was frequently at the expense of voice quality and significant morbidity or mortality. A new highly successful endoscopic technique is described for the treatment of posterior glottic stenosis (apparent bilateral vocal cord paralysis), subglottic stenosis, and tracheal stenosis up to 1 cm thick. The procedure involves the endoscopic use of the CO2 laser, and a micro-trapdoor mucosal flap. Ninety percent of the patients in the group studied obtained an adequate airway with good voice quality and no tracheotomy was required in those patients not already having one. In 19 patients there was no mortality and essentially no morbidity.

Percutaneous dilation of tracheal stenosis.

A high-grade complex tracheal stenosis distal to a tracheostomy tube occurred in a patient with a chronic vegetative state. The stenosis was easily and rapidly dilated at bedside using commercially available percutaneous tracheostomy kit dilators. Following tracheal dilation, a larger tracheostomy tube was inserted, resulting in the splinting of the stenotic area. To my knowledge, this is the first report of such a bedside technique for the dilation of a tracheal stenosis through a tracheostomy. This technique may provide a temporary relief from tracheal obstruction as long as the stenosis is within the reach of the dilator.

The surgical treatment of congenital tracheal stenosis--a report of two cases.

Two patients with congenital tracheal stenosis, one who had segmental type stenosis and the other who had extensive type stenosis, were surgically treated at our hospital. The patient with segmental tracheal stenosis was successfully treated by resection and anastomosis. Five years postoperatively, although she was asymptomatic, endoscopic examination revealed a circumferential stricture with an inner diameter of about 3 mm in the upper trachea. A second operation was thus performed to remove the stenotic trachea and her postoperative course was uneventful. The second patient was a male whose extensive tracheal stenosis was associated with vascular ring and tracheal bronchus. Division of the vascular ring was not effective and a tracheoplasty using costal cartilage was performed twice, also unsuccessfully. He is now managed with a tracheostomy, using a long endotracheal tube which was specially designed for him. A recent bronchoscopy revealed a flaccid distal trachea. In this report, we also discuss the technical problems associated with treating congenital tracheal stenosis.

Autopericardial patch tracheoplasty for tracheal stenosis after arterial switch operation.

Though congenital tracheal stenosis in infants with congenital heart disease is uncommon, congestive heart failure is often deteriorated by respiratory symptoms. We report an infant having a diagnosis of congenital tracheal stenosis complicated with congenital heart disease who underwent pericardial patch tracheoplasty after the arterial switch operation for the transposition of the great arteries. External appearance of the trachea showed no stenosis and tracheal rings were well formed. Intraoperative bronchofiberscopy transilluminated the upper border of stenosis. The trachea was opened longitudinally to the extent of 30 mm to the point from 10 mm point proximal to the bifurcation. The incision was enlarged with the autologous pericardial patch using running absorbable suture. Then pericardial patch was anchored at several points to the posterior surface of the ascending aorta, innominate artery, and to the strap muscles of the neck. He is doing well now without any respiratory symptom.

Tracheal growth in congenital tracheal stenosis.

Two cases of congenital tracheal stenosis were managed conservatively despite mild to moderate initial respiratory symptomatology in infancy. Serial CT examinations were performed on each child, with tracheal dimensions and cross-sectional areas measured in the region of stenosis at each CT examination. The examinations document increases in tracheal cross-sectional area in the region of stenosis over time, confirming tracheal cartilage growth. We present these data to dispel the hypothesis that tracheal growth does not occur in complete-ring tracheal stenosis. The selection of cases for surgical repair must be considered with the knowledge that this anomaly does not carry an inevitably poor prognosis.

Endoscopically placed expandable metal tracheal stents for the management of complicated tracheal stenosis.

BACKGROUND: Metal stents have been advocated to manage complicated tracheal stenosis. OBJECTIVE: The purpose of this investigation is to review the effectiveness of endoscopic placement of tracheal expandable metal stents for complicated tracheal stenosis. METHODS: The charts of 6 patients who have undergone placement of metal expandable stents between 1998 and 2000 were reviewed. RESULTS: Initially, all patients enjoyed immediate palliation of symptomatic tracheal stenosis. Eventually, 4 patients developed significant granulation tissue and/or recurrent stenosis, requiring intervention within 6 months after placement of the stent. One patient required the removal of the stent and placement of a T-tube silicone stent. CONCLUSIONS: Metal stents provide temporary palliation for tracheal stenosis. Metal stents, however, are associated with a high incidence of obstruction with granulation tissue. Their use should be limited to a select group of patients with a short life expectancy (because of other comorbidities) or patients who are not good candidates for reconstructive surgery and/or who refuse or cannot tolerate a tracheotomy.

A new approach to the treatment of congenital tracheal stenosis: Balloon tracheoplasty and expandable metallic stenting.

BACKGROUND/PURPOSE: Many surgical procedures have been unsatisfactory for the treatment of congenital tracheal stenosis. The authors used intraluminal balloon dilatation and expandable metallic airway stent for this condition. METHODS: From 1997 to 2000, balloon expandable stents (Palmaz) were inserted into the trachea in 5 infants, aged 7 days to 12 months who had severe airway obstruction caused by tracheal stenosis. Tracheal stents were placed after intraluminal balloon dilatation of complete tracheal rings. The stents were placed on balloon catheters and were inserted into the desired position bronchoscopically using x-ray control. They were expanded and fixed in place by inflating the balloon to appropriate diameter. The stents were 10 to 40 mm long and 6 to 8 mm in diameter. RESULTS: Four patients have been relieved of airway obstruction after this procedure. One patient died after 9 months of palliation. In all patients, granulation tissue developed over the stents and could be managed by scraping or balloon compression. Stents have been in place for 9 to 36 months after insertion without any other complication. CONCLUSIONS: Airway stents after balloon tracheoplasty can be left for prolonged periods to relieve tracheal obstruction. This technique may provide an important remedy in infants and children with congenital tracheal stenosis.

The balloon posterior tracheal split: a technique for managing tracheal stenosis in the premature infant.

Congenital tracheal stenosis (CTS) in the premature infant almost invariably leads to death for lack of effective reconstructive techniques. We hypothesized that the complete or near complete cartilaginous rings of CTS have a weak point in the posterior portion. Aggressive balloon dilation would result in a posterior longitudinal disruption of the trachea, and an expanded tracheal wall would be created after an appropriate period of endotracheal stenting. Three premature infants with multiple anomalies and CTS were treated with endoscopic posterior tracheal splitting, dividing the trachea as predicted. Although two died of complications of congenital heart disease 2 weeks after the procedure, the third child is alive and well at 9 months of age without airway symptoms. The posterior tracheal wall also split when we performed the procedure in a fresh cadaveric CTS patient. We believe that balloon dilation may prove to be a valuable technique in the treatment of premature infants with congenital or acquired tracheal stenosis and/or in children with such complex diseases that major surgery is precluded.

The use of magnetic resonance imaging to assess tracheal stenosis following percutaneous dilatational tracheostomy.

The incidence of tracheal stenosis following conventional tracheostomy has been reported as lying between one and 30 per cent. Methods used to assess the degree of stenosis include CT scanning, fibreoptic visualization and plain X-ray tomographs. The aim of this study was to assess the degree of stenosis in patients following percutaneous dilatational tracheostomy (PDT) using MRI scanning. This method has not been reported in the literature previously. Nine patients without symptoms of tracheal stenosis were studied for at least six months following PDT performed in the intensive therapy unit. The tracheas were assessed for scarring and stenosis using a three dimensional volume scanning MRI technique. Although scarring could be detected in the wall of the trachea and subcutaneous tissues of all patients, tracheal stenosis was not demonstrated at the insertion site or at the site of the cuff (p > 0.05). MRI scanning provides an excellent non-invasive method of assessing the tracheal lumen. Our patients who had undergone PDT do not appear to have any degree of post-operative stenosis.

Tracheal resection with end-to-end anastomosis for benign tracheal stenosis.

To review our experience with tracheal resection with end-to-end anastomosis for tracheal stenosis, we performed a retrospective review at a tertiary-care academic medical center. Twenty-eight patients underwent circumferential tracheal resection with end-to-end anastomosis by 2 attending otolaryngologists from 1989 to 2002. Patients were excluded if they were under 12 years of age or if the surgical indication was tracheal or thyroid neoplasm. The indications for tracheal resection were postintubation stenosis (n = 9; 32%), posttracheotomy stenosis (n = 7; 25%), both postintubation and posttracheotomy stenosis (n = 9; 32%), external tracheal trauma (n = 2; 7%), and presence of a foreign body (n = 1; 4%). Two to 8 rings were resected. The follow-up periods ranged from 18 months to 13.5 years. The anastomotic success rate was 89% (n = 25). No patients died as a result of the procedure. We conclude that tracheal resection with end-to-end anastomosis is a relatively safe and reliable procedure for the treatment of tracheal stenosis in appropriately selected patients.

Primary reconstruction of airway after resection of subglottic laryngeal and upper tracheal stenosis.

Eighteen patients with low subglottic laryngeal stenosis and upper tracheal stenosis underwent resection of the anterior and lateral cricoid cartilage and upper trachea with reconstruction by primary laryngotracheal anastomosis. The posterior cricoid plate and recurrent laryngeal nerves were preserved. The distal trachea was tailored obliquely with an anterior prow and was anastomosed to the thyroid cartilage anteriorly and to the residual cricoid posteriorly. Where the stenosis was circumferential, scarred mucosa was resected from the anterior surface of the posterior cricoid lamina and the defect covered with a tailored flap of membranous tracheal wall. In 14 patients the lesions followed intubation injury. In 2 the stenosis was idiopathic. One stenosis resulted from inhalation burn and one from localized amyloidosis. Many patients had undergone previous surgical repairs. Sixteen patients had good to excellent results from six months to five and one-half years later. Reconstruction of the burned airway failed. One additional patient is still under treatment with a T tube.

[A case of subglottic tracheal stenosis following tracheostomy successfully treated with laryngo-tracheal anastomosis].

A 77-year-old male patient underwent laryngo-tracheal anastomosis for subglottic tracheal stenosis. He developed exertional dyspnea 10 month after tracheostomy. Anterior and lateral wall of the cricoid cartilage and the first two tracheal cartilages were resected, preserving the recurrent laryngeal nerves. The distal trachea was anastomosed to the thyroid cartilage primarily and tracheostomy was made at 6th tracheal ring. Postoperatively, anterior flexion of the neck was maintained for a week. Oral intake was started on the 2nd postoperative day. The patient showed smooth recovery. The important points of this operation are: 1) preoperative evaluation of the residual subglottic space, 2) intraoperative care for preservation of the recurrent nerves, especially at the lateral sides of the crycoid cartilage, and 3) postoperative maintenance of the cervical anterior flexion.

Tracheoplasty for tracheal stenosis in the pediatric burned patient.

Until recently, the only therapy available for a tracheal stricture has been repeated dilations of the stenotic area or resection and anastomosis. Upper-airway burns in the pediatric patient have occasionally resulted in tracheal stenosis. Two children with a long tracheal stenosis secondary to inhalation injury have been successfully treated surgically. A costal cartilage graft has been used in these two children in the management of a long tracheal stenosis. Both have an adequate airway, and future surgical correction of a subglottic stenosis is planned for both. The results, although initially successful, will need to be tested by time before they can be considered the definitive treatment for long areas of tracheal stenosis.

[Initial experience with surgical treatment of tracheal stenosis in small children using extracorporeal circulation].

Severe tracheal stenosis represents a life threatening malformation which necessitates early surgery. Two patients aged one and two years, respectively, were followed-up for signs of congenital stridor. Following respiratory infection both children became critically ill with severe dyspnoea necessitating intubation and artificial ventilation. In the first patient, echocardiography, tracheobronchoscopy and other investigations revealed a pulmonary artery sling with tracheal compression and hypoplasia of the whole trachea. In the second child, presence of a short local tracheal stenosis was found, the cause of which could not be clarified. In the patient with the pulmonary sling, resection and reimplantation of the anomalous left pulmonary artery was performed first. In both children, however, surgical reconstruction of the lower airways was necessary. Surgery was performed from a midline sternotomy approach in extracorporeal circulation. The hypoplastic trachea with circular rings in the first child was enlarged with a pericardial patch. In the second child, the local tracheal stenosis was resected and a direct anastomosis of the trachea was performed. In both patients, transient formation of granulations was observed. Both children, however, survived and their clinical condition remains good 18 and 9 months, respectively, after surgery. Tracheobronchoscopic controls show very good result. Our experience confirms the possibility of successful surgical reconstruction of lower airways in young children using extracorporeal circulation. Good interdisciplinary cooperation between the surgeon and other specialists is an important prerequisite of good surgical results.
