Conservative surgical management of tracheal stenosis.

Tracheal stenosis has become an increasing complication following tracheostomy or prolonged intubation for mechanical ventilation and is directly related to trauma. Tracheal resection up to 4 to 5 cm with end-to-end anastomosis is the generally accepted treatment. However, tracheal resection carries mortality and considerable morbidity. From 1974 to 1977 all patients seen with tracheal stenosis, regardless of the etiology and age, were initially treated with a conserative surgical management. It consists of dilation, severance of the stenotic ring, intralesional injection of triamcinolone acetonide, and stenting with a silicone T tube for 90 days. Nine out of 11 patients had good results and enjoy an adequate airway without a tracheostomy tube. The longest follow-up is three years and the shortest is eight months. Intralesional injection of triamcinolone acetonide is essential for a successful treatment. No serious complications due to this treatment have occurred. This technique appears worthy of trial prior to contemplating a more extensive procedure.

Diagnosis and management of tracheal stenosis.

Tracheal stenosis is defined as cicatricial narrowing of the endotracheal lumen. Endotracheal manipulation remains to be the most common etiology followed by inflammatory and collagen vascular diseases. Predisposing factors include host systemic conditions such as gastroesophageal reflux and tube characteristics mainly the size and composition of the tube. The clinical picture may be misleading and ranges from mild decrease in exercise tolerance to severe respiratory distress. The patient is usually investigated radiologically followed by flexible or rigid laryngoscopy and bronchoscopy. Computerized tomography is used more often than magnetic resonance imaging and correlates well with the endoscopic findings. The cervical portion of the trachea is usually involved with marked narrowing varying in length and diameter. The treatment includes endoscopic repair, laryngotracheal reconstruction or segmental resection with end to end anastomosis. A total of thirteen cases of adult tracheal stenosis, diagnosed and managed at the American University of Beirut between 1996 and 2003 were reviewed. The clinical presentation, etiology, diagnostic and therapeutic approaches are presented in this study.

Use of the silicone T-tube to treat tracheal stenosis or tracheal injury.

BACKGROUND: Tracheal stenosis or tracheal injury is a troublesome disease. Traditional temporary tracheostomy and reconstruction can resolve some problems. However other problems such as subglottic stenosis and supracarinal stenosis, cannot be resolved by simple tracheostomy. The silicone tracheal T-tube presents a substitute for stent of this complicated disease. METHODS: Eleven patients with tracheal stenosis or tracheal injury were managed with the silicone T-tube prosthesis from 1995 to 1999. Among them 5 cases were characterized by subglottic and cervical stenosis, 4 cases supracarinal stenosis, and 2 cases tracheal injury. The silicone T-tube was used for about one year in all patients with satisfactory results. RESULTS: One patient was excluded from the study because of death due to unrelated disease. The T-tubes were removed successfully one year later. Among them, two patients with granuloma over the subglottic area were treated by CO(2) laser 2 to 4 times. The stoma was closed by repeated silver nitrate application. CONCLUSIONS: The silicone T-tube is a useful prosthesis for tracheal stenosis or tracheal injury with minimal complication in place of traditional tracheostomy or complex tracheal reconstruction.

Emergency management of tracheal stenosis. Retrograde tracheal bougienage.

A new technique for immediate though temporary relief of airway obstruction due to tracheal stenosis is described. Introduction of a small gauge cuffed endotracheal tube past the stenotic segment, followed by repeated withdrawal with the cuff inflated, allows for effective and safe retrograde bougienage. Airway patency is maintained throughout. Following this procedure introduction of an endotracheal tube or tracheostomy cannula is facilitated and definitive surgery can be planned.

Adult long-segment tracheal stenosis attributable to complete tracheal rings masquerading as asthma.

OBJECTIVE: a) To report on an adult patient with congenital long-segment tracheal stenosis from complete tracheal rings complicated by tracheomalacia; b) to highlight the fact that some patients with airway narrowing could be misdiagnosed as having bronchial asthma; and c) to discuss our management with a custom-made tracheostomy tube extending to the carina. DESIGN: Case report. SETTING: A university hospital's 14-bed medical/surgical intensive care unit. PATIENT: A 21-yr-old patient, with a history of what was labeled as asthma, was admitted to the intensive care unit with diabetic ketoacidosis, pneumonia, respiratory failure, and septic shock. INTERVENTIONS: Her therapy included assisted mechanical ventilation through an endotracheal tube. Initially, a size 6.0 endotracheal tube was used. Finally, a custom-made tracheostomy tube extending to the carina was inserted to manage her persistent infantile trachea. MEASUREMENT AND MAIN RESULTS: During 4 months in the intensive care unit, she suffered numerous airway problems from her narrow trachea that were eventually attributed to congenital long-segment tracheal stenosis from complete tracheal rings. Bacterial pneumonia, viral tracheobronchitis, and tracheomalacia complicated her course. Multiple attempts at extubation failed and, after translaryngeal endotracheal tubes and tracheostomy tubes of decreasing size, her airway was managed with a size 5.0 custom-made tracheostomy tube with the tip extending to her carina. She was totally dependent on this tube. CONCLUSION: Airway narrowing may masquerade as asthma. Congenital tracheal stenosis is rare and is associated with a high mortality rate. Complete tracheal rings presenting in adulthood are extremely rare, and we report the first case of long-segment pantracheal stenosis presenting in adulthood. Surgical treatment with tracheoplasty is difficult. A custom-made tracheostomy tube to stent the entire trachea is one management option. Tracheal stenosis should be excluded in patients with a chronic lack of response to therapy for asthma.

Tracheoplasty in congenital tracheal stenosis.

Congenital tracheal stenosis is an uncommon but life-threatening condition whose management is still debated. The rarity of this disease explains the lack of a standard management. Between 1986 and 1996, eight children younger than 1 year were referred to our Institution with a tracheal stenosis. The median age at operation was 3.15 months and the median weight was 4.5 kg. The diagnosis was made after an episode of respiratory distress in all but one and was confirmed by fiberoptic bronchoscopy. The median length of tracheal stenosis was 24.5 mm (Ranges: 4-30 mm). Only one patient was free from associated cardiovascular defect. Tracheal repair was performed under cardiopulmonary bypass in all. In three it was achieved by pericardial augmentation of the stenosed area, in four by resection and end to end anastomosis and in one by sliding tracheoplasty. Concomitant cardiac repair was performed in six. Two patients died after pericardial patch augmentation. In both, death was related to profound hypoxemia due to patch collapse. Two patients developed restenosis after resection and end to end anastomosis. They both had stent placement and one required reoperation and underwent a sliding tracheoplasty. At a median follow-up of 21 months (Ranges: 6-120) all the survivors are doing well and are free from respiratory symptoms. Bronchoscopic evaluation revealed in all a widely patent anastomosis without restenosis. In conclusion, tracheal stenosis in children remains a challenging lesion. Surgical technique, whether resection and end to end anastomosis or sliding tracheoplasty offer better results and should be discussed according to the length of the stenosis. Pericardial plasty should be used with caution.

Detection of tracheal stenosis by frequency analysis of tracheal sounds.

To develop a simple noninvasive method for detecting tracheal stenosis, tracheal sounds were analyzed using fast-Fourier transform. The subjects were all female and included 5 normal volunteers and 13 patients with tracheal stenosis mostly secondary to thyroid cancer (11 extrathoracic and 2 intrathoracic lesions). Tracheal sounds were recorded during spontaneous breathing and were digitized with an analog-to-digital converter. Pulmonary functions, including forced expiratory volume in 1 s (FEV1) expressed as percentage of vital capacity, peak expiratory flow rate (PEFR), the ratio of FEV1 to PEFR (Empey's index), and the ratio of expiratory to inspiratory flow rates at 50% vital capacity, were measured. A computed tomography scan was used to obtain the tracheal minimum cross-sectional area. Whereas PEFR demonstrated a weak correlation with the stenotic area, FEV1%, Empey's index, and the ratio of expiratory to inspiratory flow rates at 50% vital capacity did not. The power of the fast-Fourier transform spectrum of normal tracheal sounds decreased as the frequency increased up to 500 Hz. A small spectral peak was observed at approximately 1 kHz. Patients with significant tracheal stenosis demonstrated an increase in the peak spectral power at approximately 1 kHz and in the mean spectral power from 600 to 1,300 Hz in their tracheal sounds. In patients with extrathoracic lesions, the peak and mean spectral powers correlated well with the area of the stenosis as defined by computed tomography scan. In patients with intrathoracic lesions, abnormalities in the pulmonary functions as well as tracheal sound spectra appeared more evident despite milder stenoses.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of idiopathic tracheal stenosis.

Idiopathic tracheal stenosis (ITS) is an extremely rare disease. We report the case of a 32-year-old woman with ITS. She had no history of previous surgery, endotracheal intubation, neck trauma, granulomatous disease, or any other severe respiratory tract infections. She presented with progressive dyspnea on effort and had been treated for bronchial asthma for 3 years. Chest radiography and laboratory examinations revealed no abnormalities. Bronchoscopy demonstrated almost circumferential tracheal stenosis extending for 10 mm from about 20 mm below the vocal cords. Luminal diameter was about 4 mm at the narrowest. Bronchoscopic biopsy revealed increased fibrous tissue and chronic inflammatory cell infiltration (nonspecific inflammatory tissue). These finding are compatible with idiopathic stenosis as reported by Grillo et al. After tracheostomy, the patient was treated by tracheal segmental resection (two rings) with end-to-end anastomosis of the cartilaginous trachea. Symptoms of tracheal stenosis were completely relieved and no recurrence has been observed as of 3 years postoperatively.

Diagnosis and management of pediatric tracheal stenosis.

Pediatric tracheal stenosis is a difficult problem that requires very careful preoperative evaluation and classification. Most forms of extrinsic compression are vascular in origin but can be associated with tracheomalacia, complete tracheal rings, and other anomalies of the aerodigestive tract. Optimally, both the vascular malformation and the intrinsic tracheal malformation should be repaired at the same procedure. Long tracheal stenosis, most commonly caused by complete tracheal rings, is best treated by pericardial patch tracheoplasty or cartilage augmentation. Areas of short-segment intrinsic stenosis can sometimes be corrected endoscopically with or without intraluminal stenting, depending on severity. When endoscopic methods fail, resection with end-to-end anastomosis is the procedure of choice for short-segment stenosis.

Surgical management of congenital tracheal stenosis.

Congenital tracheal stenosis is a rare and potentially lethal malformation. Although congenital tracheal stenosis carries a high mortality rate, advances in surgical treatment have increased the likelihood of survival, and these patients are seen with increasing frequency in intensive care units. The surgical options available are dilation, resection, and tracheoplasty. Because of the lack of a prosthetic replacement, resection is generally limited to lesions involving less then one third of the trachea. Tracheoplasty with a variety of graft materials has, in some cases, been successful in increasing the diameter of the stenotic trachea. Postoperative care involves maintaining paralysis and sedation until healing is established, with close attention to preventing complications. The needs of the family are addressed through teaching and support. A case of successful tracheal reconstruction, by use of an autologous cartilage graft, in a 14-day-old infant with severe stenosis from just below the vocal cords extending to the hilum is presented.

Surgisis patch tracheoplasty in a rodent model for tracheal stenosis.

BACKGROUND: Tracheal stenosis is a challenging surgical problem that can require reconstruction using autologous grafts or artificial stents. In this study, we evaluate the efficacy of Surgisis, a commercially available, biocompatible, acellular matrix, in the repair of a critical-size tracheal defect. METHODS: A full-thickness defect (2 mm x 6 mm) was created in tracheal rings 4 through 6 in adult rats. A piece of 8-ply Surgisis (Cook; Bloomington, IN) was sutured to the edges of the defect with interrupted 8-0 polypropylene sutures. In control animals, the defect was closed primarily. The trachea was harvested at 4 weeks and prepared for histologic evaluation using conventional techniques. Cross-sectional area and perimeters were calculated using imaging software. RESULTS: Tracheal defects without patch repair (n = 3) resulted in tracheal stenosis and immediate death. Animals that underwent Surgisis patch repair of tracheal defects (n = 10) tolerated the procedure well and had no audible stridor or evidence of respiratory distress. Eight of ten animals survived 4 weeks. The tracheal lumen was patent with no evidence of contracture or degradation of the Surgisis. Histologically, neovascularization of the Surgisis was noted with moderate inflammation. The surface of the Surgisis patch was covered ith a lining of ciliated epithelial cells. CONCLUSION: In the rodent model, Surgisis appears to be an efficacious method for the patch repair of partial circumferential tracheal defects. Surgisis appears to be a safe and promising means of facilitating neovascularization and tissue regeneration. The long-term use of Surgisis warrants further investigation.

Repair of congenital tracheal stenosis with a free tracheal autograft.

OBJECTIVES: Evaluate the results of a technique for repair of congenital tracheal stenosis by use of a free tracheal autograft. METHODS: Between January 1996 and July 1997, six infants with congenital tracheal stenosis resulting from complete tracheal rings underwent repair with a free tracheal autograft. Mean age at the time of repair was 4.9 months; mean weight was 5.4 kg. The approach was through a median sternotomy with cardiopulmonary bypass for respiratory support. The trachea was incised anteriorly through the area of stenosis, the midportion of the stenotic trachea was excised, and an end-to-end anastomosis was carried out posteriorly. The excised tracheal segment (1.3 to 2.2 cm long) was used as a free autograft to patch the lower trachea anteriorly. In four infants the autograft was augmented in the upper trachea with pericardium; in two patients with a shorter length of stenosis, the autograft completed the repair. Simultaneous pulmonary artery sling repair (4), ligation and division of patent ductus arteriosus (3), cricoid split (2), atrial and ventricular septal defect repair (1), and complete atrioventricular canal repair (1) were performed at the time of tracheal repair. RESULTS: The infants were extubated and discharged at a mean of 13 and 23 days postoperatively, respectively. One infant had recurrent tracheal stenosis related to the pericardial patch and required a tracheal stent and tracheostomy 4 months postoperatively. Our mean follow-up is 11 months. Bronchoscopic findings currently show widely patent tracheal lumina in all infants. CONCLUSIONS: The technique of free tracheal autograft with and without pericardial augmentation was successful in opening the airway of six infants with congenital tracheal stenosis and is currently our procedure of choice for children with this diagnosis.

Postintubation tracheal stenosis.

Postintubation tracheal stenosis is a clinical problem caused by regional ischemic necrosis of the airway. The incidence of postintubation tracheal stenosis has decreased with recognition of its etiology and modifications in the design and management endotracheal and tracheostomy tubes; however, it remains the most common indication for tracheal resection and reconstruction. Single-stage resection and reconstruction by a competent tracheal surgeon results in good or satisfactory results in 93.7% of patients, with a failure rate of 3.9% and a mortality rate of 2.4%. The intellect and skill of Dr. Grillo has made the etiology and management of postintubation stenosis obvious to us all.

Association of Down syndrome and segmental tracheal stenosis with ring tracheal cartilages: a review of nine cases.

Four patients with Down syndrome and midtracheal stenosis, three with proven absence of the midtracheal pars membranacea ("hourglass trachea"), are reported. Five previously reported patients who had Down syndrome and tracheal stenosis of this type are summarized. Respiratory difficulty and stridor were the reported clinical features of all but one of the patients whose clinical story is available. That approximately half the patients with tracheal stenosis with hourglass trachea and midtracheal absence of the tracheal pars membranacea reported had Down syndrome suggests that the association of this pattern of congenital tracheal stenosis with Down syndrome is, although infrequent, significant.

Anterior pericardial tracheoplasty for congenital tracheal stenosis.

Congenital tracheal stenosis may be a life-threatening anomaly not relieved by airway intubation. Over the past 7 years, anterior pericardial tracheoplasty has been used at our institution for treatment of congenital long-segment tracheal stenosis in infants with impeding airway obstruction. Case histories of eight patients undergoing nine anterior pericardial tracheoplasties have been reviewed to assess this technique. Of these patients, six have required preoperative tracheal intubation before repair to maintain ventilation. The surgical technique of anterior pericardial tracheoplasty includes a median sternotomy approach with partial normothermic cardiopulmonary bypass. An anterior tracheotomy through all hypoplastic rings allows enlargement with autologous pericardium to 1.5 times the predicted normal diameter. After insertion, the pericardium and hypoplastic tracheal cartilages are suspended to surrounding mediastinal structures, which prevents airway collapse. Seven of eight infants have survived without tracheoplasty dehiscence or wound infections. Five were ultimately extubated and are currently free of symptoms from 6 months to 5 years after anterior pericardial tracheoplasty. The other two survivors had residual stenosis as a result of complications of prior tracheostomy. One of these patients has undergone a successful second anterior pericardial tracheoplasty and is currently extubated and well. The other is palliated at 6 months with a tracheostomy awaiting a second anterior pericardial tracheoplasty. Our review of anterior pericardial tracheoplasty has demonstrated the safety, utility, and at least medium-term benefit of this procedure in infants of any age and weight.

A new technique for T-tube insertion in tracheal stenosis located above the tracheal stoma.

Tracheal stenosis is one of the main complications of long-term intubation. The Montgomery T-tube is a safe way to treat patients with tracheal stenosis who are unable to undergo surgical procedures. We describe a simple and practical technique for the insertion of the T-tube in tracheal stenosis located above the tracheostomy, while maintaining ventilation throughout the whole procedure.

Alternative approach to the surgical management of congenital tracheal stenosis.

Congenital tracheal stenosis is a serious disease associated with high operative mortality and morbidity, especially in the newborn period. Its surgical management involves either sliding tracheoplasty, which is associated with extensive dissection and recurrent stenosis, or with pericardial patch tracheoplasty that fails to address recoiling of the stenotic complete ring and collapse of the patch into the tracheal lumen. We report a modification of the latter technique, in which a half ring external stenting device is used to keep the rings from recoiling.
