Long-segment congenital tracheal stenosis: treatment by slide-tracheoplasty.

BACKGROUND/PURPOSE: The prognosis of long-segment funnel-shaped congenital tracheal stenosis improved with surgical management by enlargement-tracheoplasty with a pericardial patch. However, the final outcome is not always satisfying mainly because of the complications related to the pericardial graft and because of misdiagnosed associated cardiovascular malformations. The objective of the report is to show a further improvement of the prognosis by a thorough preoperative planning and the use of a slide-tracheoplasty for the cure of the stenosis, to avoid the major drawbacks of enlargement tracheoplasties. METHODS: Two children, 7 months and 3 years old, underwent a bronchoesophagoscopy, spiral computed tomography, an echocardiogram, and a heart catheterization. The tracheal stenosis and the associated severe cardiovascular malformations were cured during a single operative session under cardiopulmonary bypass; the tracheal stenosis was corrected by a slide-tracheoplasty. RESULTS: The postoperative period was remarkably uneventful and the recovery extremely quick (hospital stay of 18 and 17 days). The midterm results are excellent, and the tracheal growth is not impaired (follow-up of 3 1/2 and 3 years). CONCLUSIONS: According to the authors' experience and to the literature, the slide-tracheoplasty seems to be the most efficient surgical procedure for correction of long-segment funnel-shaped congenital tracheal stenosis. But the success of the treatment depends also on a complete preoperative diagnosis allowing a 1-stage surgical treatment of all associated thoracic malformations.

Congenital Heart Surgery Nomenclature and Database Project: vascular rings, tracheal stenosis, pectus excavatum.

The extant nomenclature for vascular rings, tracheal stenosis, and pectus deformities is reviewed for the purpose of establishing a unified reporting system. The subject was debated and reviewed by members of the STS-Congenital Heart Surgery Database Committee and representatives from the European Association for Cardiothoracic Surgery. All efforts were made to include all relevant nomenclature categories using synonyms where appropriate. Vascular rings are subclassified as double aortic arch, right arch/left ligamentum, pulmonary artery sling, and innominate compression. Tracheal stenosis is subclassified as congenital complete tracheal rings (localized or long-segment) or acquired postintubation types. Pectus deformities are subclassified as pectus excavatum and carinatum (mild, moderate, severe). A comprehensive database set is presented which is based on a hierarchical scheme. Data are entered at various levels of complexity and detail which can be determined by the clinician. These data can lay the foundation for comprehensive risk stratification analyses. A minimum database set is also presented which will allow for data sharing and would lend itself to basic interpretation of trends. Outcome tables relating diagnoses, procedures, and various risk factors are presented.

[Treatment of tracheal stenosis or obliteration].

The authors present the material of 55 patients, who were treated in ENT Department of Medical University of Bydgoszcz between 1992 and 2002. The authors distinguish four groups of patients: 1) with the tracheal stenosis or obliteration, who had to be treated by excision of the stenosed part of the trachea, 2) with the tracheal stenosis treated with laser CO2 beam, 3) with the tracheal stenosis treated by laryngectomy before, 4) not treated surgically because of different reasons. The authors present diagnostic and therapeutical problems in each group on the basis of the observed material. They also discuss application of laryngeal neurostimulator during the operation of cutting out the stenotic or obliterated part of trachea. On the basis of the analysis of presented material they express opinion that the term "tracheal stenosis" includes a number of different pathological cases requiring different diagnostic and treatment procedures. They also think that pathological changes called "tracheal stenosis" should be treated in clinical centers with long experience and proper equipment.

Laryngeal mask airway and high-frequency jet ventilation for the resection of a high-grade upper tracheal stenosis.

The surgical resection of a high-grade tracheal stenosis presents a special case of a difficult airway. A 20-year-old male was treated for a 45-mm long tracheal stenosis with 60% reduction of the patent airway area beginning 25 mm below the glottis. To avoid manipulations of the affected segment before surgical exposure of the trachea was established, strictly supraglottic ventilation via a laryngeal mask airway was performed. During removal of the stenosis and creation of the anastomosis, transglottic high-frequency jet ventilation (HFJV) is a convenient technique that enables optimal access to the operation field. Changing from HFJV to conventional ventilation after completion of the anastomosis is not necessary, and the jet catheter can be left in place until the end of the anesthesia.

[Tracheal intubation for emergent tracheostomy in a patient complicated with tracheal stenosis].

We report the management of anesthesia for emergent tracheostomy in a patient with severe tracheal stenosis. A 63-year-old male was scheduled for an emergency tracheostomy for severe tracheal stenosis due to the invasion of a thyroid cancer. A preoperative neck CT revealed the tracheal stenosis, extending from 1-2 cm below the vocal cord to the upper end of the sternum. The narrowest caliber was about 7 mm in transverse diameter. Moreover, the cancer was suspected to have a bleeding tendency. General anesthesia with endotracheal intubation was considered necessary to provide an open airway during tracheostomy. Anesthesia was induced with thiopental, and a 6.0 mm endotracheal tube with cuff was successfully introduced with a balloon introducer (AIRGUID E) using suxamethonium. We were able to perform tracheostomy uneventfully.

Tracheal stenosis: the long and the short of it.

PURPOSE: The aim of this study was to present slide tracheoplasty as the procedure of choice for tracheal stenosis. From 1990 through 1997, patients referred to University of California, San Francisco for tracheal stenosis were managed by resection and anastomosis. During this period, other centers reported successful use of slide tracheoplasty and, from 1998 to 1999, we performed 3 slide tracheoplasties in addition to 3 more resection and anastomosis procedures. METHODS: Between 1990 and 1999, 9 patients with tracheal stenosis of varying lengths underwent surgery at the University of California, San Francisco. They were treated surgically with either resection and anastomosis or with slide tracheoplasty. RESULTS: Two of the 6 patients treated by resection and anastomosis had an anastomotic breakdown; all 3 patients undergoing slide tracheoplasty did not have anastomotic problems. Technically, a slide tracheoplasty has only one half the tension distributed over an oblique anastomosis that is more than the circumferential length of a resection and anastomosis approach. CONCLUSION: Based on these results, a slide tracheoplasty may be the procedure of choice for tracheal stenosis, whether long or short.

Efficacy and tolerance of a new silicone stent for the treatment of benign tracheal stenosis: preliminary results.

STUDY OBJECTIVE: In inoperable patients with tracheal stenosis who are treated using silicone stents, stent migration occurs in 18.6% of cases. To decrease the migration rate, we have designed a new silicone stent with narrow central and larger distal parts. This study analyzes the stability and tolerance of this new stent. DESIGN: Preliminary prospective study conducted in two French university hospitals. PATIENTS: Thirteen inoperable patients with benign complex tracheal stenosis due to intubation or tracheotomy. INTERVENTIONS: Tracheal stent insertion was performed under general anesthesia with a rigid bronchoscope. The patients were followed up clinically up to stent removal, which was planned at 18 months. RESULTS: Stent insertion or removal was very simple and did not differ from other silicone stents. No migration occurred after a mean follow-up of 22.8 months. Minimal granuloma formation occurred in only one patient (7.7%). Sputum retention remained similar to that with other silicone stents and could be improved by a smoother internal wall. Stents have been removed in seven patients after a mean duration of 19.6 months, with a complete stenosis cure in four cases. CONCLUSION: This new stent combines the excellent stability of the metallic stents and the tolerance and easy removal of straight silicone stents. This allows a prolonged use in order to obtain curative action.

MRI in pre- and postoperative assessment of tracheal stenosis due to pulmonary artery sling.

OBJECTIVE: To evaluate the potential of MRI in the assessment of tracheal stenosis due to tracheal or vascular malformations, 45 children with severe respiratory distress were examined prospectively during a period of 1 year. Five of these children had tracheal stenosis due to a sling left pulmonary artery (SLPA). MATERIALS AND METHODS: Magnetic resonance examinations of the anesthetized children were performed with a 1.5 T Siemens MR imager using electrocardiographically gated T1-weighted SE sequences in transverse and sagittal slice orientations. Slice thickness was 3 mm and each sequence was repeated after shifting the slice position by 1 mm. Monitoring during the examinations included ECG, oscillatory blood pressure, respiratory rate, and oxygen concentration. Magnetic resonance findings were compared with esophagography, selective pulmonary angiography, bronchoscopy, Doppler sonography, and surgery. All examinations were repeated after surgical therapy to assess the improvement in tracheal stenoses and the patency of the ligated and reimplanted left pulmonary arteries. RESULTS: Magnetic resonance imaging clearly revealed the course of the SLPA and its topographic relationship to the trachea as well as the coexistence of cardiovascular and tracheobronchial or esophageal malformations. The degree and length of tracheal stenoses, which were measured in the pre- and postoperative axial slices and graphically displayed, as well as the angles of the right and left main stem bronchi, could be accurately determined. CONCLUSION: Magnetic resonance imaging in combination with bronchoscopy yielded the necessary and sufficient information for diagnosis and aided the surgeon in planning operative strategy and in postoperative follow-up.

Esophageal tracheoplasty for congenital tracheal stenosis.

Two infants with congenital long tracheal stenosis underwent operation by means of an esophageal tracheoplasty. The first patient had previously undergone tracheal reconstruction using the pericardium. Although ventilation improved somewhat following this procedure, the pericardial patch suddenly ruptured 12 days after the operation, requiring an immediate esophageal tracheoplasty. The esophageal portion of the reconstructed trachea epithelialized 1 month later, with the lumen maintaining its proper size. However, the patient died 3 months after the second tracheoplasty. The cause of death was thought to be due to complications arising from prolonged high-pressure use of mechanical ventilation. He had been on a respirator for 6 months before the first tracheoplasty. The second patient has been doing well with no recurring respiratory problems for 25 months now. Her reconstructed trachea has adapted with her growth. This technique should be considered along with other forms of treatment for tracheal reconstruction because it is relatively simple and pliable.

The significance of tracheal stenosis in esophageal atresia.

The significance of tracheal stenosis in children operated upon for esophageal atresia is described. Stenosis is caused mainly by tracheal compression by the innominate artery leading to tracheal malacia. Following esophageal repair tracheal compression is increased causing life-threatening asphyctic attacks during feeding. After establishment of diagnosis urgent surgery by means of truncopexy is indicated. The incidence of this complication is about 1 in 20 according to our figures and 1 in 40 according to Filler (Filler et al. 1976).

Effect of corticosteroids on post-intubation tracheal stenosis.

A 57 year old patient presented with progressive tracheal stenosis two months after intubation. An intraluminal polypoid lesion was found at the site of the cuff of the endotracheal tube. It disappeared within five days of treatment with inhaled beclomethasone. Further improvement of forced expiratory and inspiratory flow occurred after systemic corticosteroid treatment, with resolution of peritracheal oedema. Topical and systemic corticosteroids may be useful in the management of early post-intubation tracheal stenosis.

Congenital tracheal stenosis: report of three cases.

Three infants of congenital tracheal stenosis were experienced in our hospital from 1987 to 1990. They were free from perinatal insult with the onset of symptoms at less than three months of age. Their clinical course deteriorated progressively and all died of respiratory failure in spite of the use of respirator and intensive care. One case received tracheoplasty 2 days before he died. This rare disease entity confronts neonatologist and pediatric surgeon with very high mortality. Only certain types of this disease may be corrected by advanced reconstructive surgery. Congenital tracheal stenosis is usually diagnosed by bronchoscopy, bronchography, xerography or computed tomography. The clinical characteristics and therapeutic management of our cases are discussed and literatures reviewed.

Long-segment tracheal stenosis: slide tracheoplasty and a multidisciplinary approach improve outcomes and reduce costs.

OBJECTIVE: Long-segment tracheal stenosis is rare, life-threatening, difficult, and expensive to treat. Management remains controversial. A multidisciplinary tracheal team was formed in 2000 to deal with a large number of children with airway problems referred for management. We review the effect of that service, comparing the era before and after the establishment of the multidisciplinary tracheal team. METHODS: From January 1998 through January 2004, 34 patients with long-segment tracheal stenosis (21 patients with cardiovascular anomalies) underwent surgical intervention. Cardiopulmonary bypass was used in all operations. Before the multidisciplinary tracheal team, pericardial patch tracheoplasty with or without an autograft technique was the preferred method of repair. After the multidisciplinary tracheal team, an integrated care plan preferring slide tracheoplasty was initiated, correcting cardiac lesions simultaneously. RESULTS: Before the establishment of the multidisciplinary tracheal team, pericardial patch tracheoplasty was performed in 15 of 19 patients. Twelve patients had a suspended pericardial patch tracheoplasty, 2 (17%) of whom died late after the operation. Of 3 patients who had had a simple unsuspended patch, 2 (67%) died early after the operation. Four patients were operated on with the tracheal autograft technique, 2 (50%) dying early in the postoperative period. After multidisciplinary tracheal team formation, in the era between 2001 and 2004, 15 patients were operated on with slide tracheoplasty, and there were 2 (13%) early postoperative deaths. A significant reduction in cost and duration of stay has been shown both in the intensive care unit and the hospital. CONCLUSION: Our data suggest that a formalized multidisciplinary team approach and a policy of primary slide tracheoplasty are beneficial in the management of children with long-segment tracheal stenosis.

Prognostic factors in the surgical treatment of congenital tracheal stenosis: a multicenter analysis of the literature.

BACKGROUND: Congenital tracheal stenosis (CTS) often requires urgent surgical intervention. We evaluated prognostic factors to determine the risks of surgical interventions by conducting a retrospective review of recent case series. METHODS: Cases of CTS between 2002 and 2004 from our institution and recently published series that provided primary data on the demographics, complications, and outcomes of patients with CTS were analyzed. Univariate, model fit, and multivariate logistic regression analyses were performed using the SAS Statistical Program. RESULTS: There were 68 patients who were treated (cartilage patch tracheoplasty, n = 31; slide tracheoplasty, n = 37), with 19 deaths (overall mortality = 28%). A total of 10 patients who underwent cartilage patch tracheoplasty died (32% mortality), whereas only 9 patients died following slide tracheoplasty (24% mortality). A total of 8 of 11 patients who were repaired at the age of 1 month or younger died (73% mortality), whereas only 11 of 57 patients who were repaired at an age older than 1 month died (19% mortality) (P = .04). A total of 10 of 19 patients with CTS who had comorbid intracardiac anomalies died following CTS repair (53% mortality), whereas only 9 of 49 patients with CTS who did not have intracardiac anomalies died (18% mortality) (P = .02). CONCLUSIONS: This is the first report on the prognostic factors determining surgical outcomes for CTS. The highest mortality rate was observed in CTS patients younger than 1 month and in those with intracardiac anomalies. Congenital tracheal stenosis repairs in these patient subgroups should be considered with caution.

[Treatment of congenital tracheal stenosis. Retrospective study of thirteen cases].

Thirteen cases of congenital tracheal stenosis (CTS) were retrospectively studied in terms of operative indication and treatment. The intratracheal transverse ratio of the stenotic/normal diameter (stenotic ratio, SR) was obtained by chest X-ray, tracheogram or autopsy, as one of the parameters of stenosis. SR ranged from 0.14 to 0.50 (mean 0.35 +/- 0.13 SD). Two cases (SR = 0.14) received tracheal resection and reanastomosis successfully. In three cases with pulmonary artery sling (PAS), PA translocation was performed to release tracheal compression. One (SR = 0.49) had good result but two (SR = 0.20, 0.30) died from respiratory failure (RF) and autopsy revealed PAS. Four cases underwent surgery for congenital heart disease (CHD), 3 (SR = 0.41, 0.46, 0.49) had good results but one (SR = 0.36) died from RF. In four cases medically treated, 3 (SR = 0.40, 0.44, 0.50) improved with growth but one (SR = 0.25) died before operation due to RF and autopsy revealed PAS. When SR greater than or equal to 0.40, cases without PAS improved with conservative treatment, those with PAS improved by PA translocation, and those with CHD tolerated open heart surgery. When SR less than 0.40, tracheal reconstruction is indicated. Cases with PAS would require primary or staged operation of PA translocation + tracheal reconstruction. The most appropriate therapy should be selected on the basis of symptoms, associated diseases and parameter of tracheal stenosis, for instance "SR".

[Treatment of congenital tracheal stenosis using a slide tracheoplasty].

Congenital tracheal stenosis (CTS) is a rare malformation that usually require corrective surgery. Resection and tracheal anastomosis is the treatment of choice when the stenosis is short. However, such an approach is not usually viable when the CTS is long, given that anastomotic pressure would be too great. New surgical techniques have allowed this serious airway malformation to be corrected satisfactorily. We report the case of a three-year-old boy with a long CTS (51% of the length of the trachea) treated with a new reconstructive technique called slide tracheoplasty. Outcome was excellent.

Slide tracheoplasty for long-segment congenital tracheal stenosis.

Resection and reconstruction of long congenital tracheal stenosis often is impossible or results in excessive anastomotic tension. Anterior tracheoplasty using a patch of pericardium or cartilage may result in granulation tissue needing repeated bronchoscopies, tracheostomy, and stents and may produce recurrent stenosis. Tracheoplasty may be performed by dividing the stenosis at midpoint, incising the proximal and distal narrowed segments vertically on opposite anterior and posterior surfaces and sliding these together. The stenotic segment is shortened by half, the circumference doubled, and the lumenal cross-section quadrupled. Approach is cervical or with partial sternotomy. Cardiopulmonary bypass is not necessary. Four patients (ages: 3 months, 3 1/2 years, 19 years, and 19 years) were so treated for stenosis of 36% to 83% of tracheal length. Blood supply was not impaired. Healing was excellent and complications were minimal.

Tracheal stenosis due to brachiocephalic artery aneurysm successfully treated with stenting.

Tracheal stenosis secondary to an aneurysm of the great vessels is a rare presentation, previously thought to be unremediable to tracheal stenting. The introduction of covered, expandable, metallic stents has led to the successful treatment of a patient with tracheal stenosis secondary to an aneurysmal brachiocephalic artery without resorting to major cardiothoracic surgery.
