  • In recent years there has been considerable interest in reconstructive surgery of the trachea for cervical tracheal stenosis developed by complication of endotracheal intubation or tracheotomy, or trauma of the neck. The methods used to reconstruct the tracheal defects can be repaired with end-to - end anastomosis, cervical flaps, and autogenous graft materials. Since Grillo had undertaken tracheal reconstruction after circumferential resection in dogs, resection and end - to - end anastomosis was used in cases of circumferential stenosis. And, costal, nasal septal and auricular cartilage have been used for the autogenous graft materials. Since Caputo and Consiglio had undergone tracheoplasty with auricular cartilage, Morgenstein reported successful repair of a tracheal defect with a composite postauricular cartilage graft. The advantages of the auricular cartilage graft are its easy accessibility, availability and familiarity to the otolaryngologist. In past 2 years, We performed the tracheoplasty with auricular cartilage graft and end- to end an astomosis after segmental resection in 5 patients who had suffered from tracheal stenosis. And we obtained good results. So, we reported the cases with review of the literatures.

  • Congenital long-segment tracheal stenosis which involves nearly entire trachea and carina is very rare disease, but leads to life threatening obstruction in infancy and childhood. Symptoms are ranged from stridor and wheezing to severe cyanosis and respiratory failure. Routine chest X-ray is somewhat helpful to diagnose it, but definitive diagnosis can be made by bronchoscopy or tracheogram for severely narrowed tracheal lumen.Recently, we experienced a case of congenital tracheal stenois, type 1 by Cantrell classification with carinal involvement. After costal cartilage was designed as oval shaped flap and covered with pericardium, anterior and posterior augmentation was done with prepared costal cartilage.This patient died of respiratory failure at 13 days postoperatively, probably due to sustaining obstruction in association in with failure to make a sufficient widening at carinal level.Important issues in the management of congenital tracheal stenosis are rapid diagnosis, selection of appropriate surgical procedure, and detailed anesthetic schedule.In the future, more biocompatible material and more effective surgical procedures should be studied to reduce the surgical mortality and morbidity of the complicated tracheal stenosis.

  • Growth of suture line and anastomosis is required for long-term success after the tracheal and bronchial surgery in infant and pediatric patient. We used various suture materials in these cases, but the results were differ. To select the adequate suture material in tracheal surgery, we tried next. Tracheal anastomoses were performed in 150 Sprague Dawley rats, aged 4 to 8 [mean 5.8] weeks and weight 62 to 106[mean 83.6] gram, to compare polydioxanone[PDS] 7-0, polyglactin 910[Vicryl]7-0, and polypropylene [prolene] 8-0 suture materials. In 150 rats, only 29[20%] were lived over 300 days, and the weight was 250 to 320[mean 289.5]gram. Cross sectional area of the anastomoses and two or three tracheal rings below anastomosis site were measured under microscope, and calculated and compared as Hsieh`s equition. Cross-sectional area,anastomosis site/normal site 100, were 89.4 $\pm$ 5.34% in PDS group[n=9], 75.7 $\pm$ 6.06% in Vicrylgroup [n = 10], and 80.8$\pm$ 4.06% in Prolene group[n = 10]. Histopathologic studies were done for all autopsies or put in death around 300 days postoperatively. PDS absorblion was not seen 16 weeks after suture but disappeared over 24 weeks slide. Vicryl absorbtion was noted postoperative 8 to 16 weeks, with marked tissue reaction. Prolene showed least tissue reaction, but the suture material was persisted with regional fibrotic capsule.Causes of death were respiratory failure in 76 cases, tracheal rupture in 22 cases, hemorrhage, biting, starvation and etc. in 23 cases. With the brief review of literatures, we report the results.

  • We report successful application of dual trachcobronchial stcnt to the diffuse tracheal stenosis. An one-month-old boy was transferred to the emergency room due to tachypnea and respiratory difficulty with COB retention. Preoperative computed tomography revealed pulmonary artery sling with diffuse tracheal stenosis. We found that the diameter of the both main bronchus was less than 3mm and the trachea was a complete ring. We divided the left pulmonary artery and implanted it to the main pulmonary artery under cardiopulmonary bypass. After that, tracheoplasty was performed with autologous pericardium. However, after the initial measures, CO2 retention and respiratory difficulty persisted due to the granulation tissue and dynamic obstruction of the airway ensued by the overlying pericardial flap. Therefore, we decided to apply a single tracheal stunt. After the insertion of tracheal stent, residual stenosis of the both main bronchus opening continued to cause respiratory difficulty Finally we applied dual tracheobronchial stent and resolved the airway obstruction.

  • A lower laryngeal and upper tracheal stenosis that is of idiopathic origin is occasionally seen. It is called an idiopathic tracheal stenosis. These circumferential fibrous stenosis is rare and they are most often located in the subglottic larynx and extend to varying distances predominantly in young women. Because of the unknown nature of the disease process and uncertainty about its future progression, patients were approached conservatively. Recently, surgical resection and reconstruction have been increasingly performed, as favorable results were obtained. Three female patients with dyspnea were admitted. For two patients, they were diagnosed this conditions as bronchial asthma by mistake. All patients were performed computed tomography and bronchoscopy. For two patients with subglottic stenosis, subglottic resection was performed by cervical collar incision, and for the other one patient with distal tracheal stenosis, tracheal resection was performed by right posterolateral thoracotomy. A diagnosis of idipathic tracheal stenosis was confirmed by postoperatively pathologic finding. For one case, because of anastomosis site infection and restenosis, a whole tracheal exposure was performed by cervical collar incision and median sternotomy. And reoperation was peformed successfully.

  • We report here 2 cases of deep-seated mediastinitis combined with sternal osteomyelitis after tracheal reconstruction which were successfully treated with sternectomy, in-situ or free omental transfer, and pectoralis major myocutaneous flap. In case I, an 8 year-old boy with deep seated mediastinitis and sternal osteomyelitis that developed after anterior tracheoplasty through a standard midline sternotomy. In case II, a 50 year-old female patient with mediastinal abcess and sternal osteomyelitis that developed after resection and end-to-end anastomosis of the trachea through an upper midline sternotomy. Treatments consisted of drainage and irrigation followed by wide resection of the infected sternum, placement of the viable omentum into the anterior mediastinal space, and chest wall reconstruction with a pectoralis major myocutaneous flap. The omentum was transferred as an in-situ pedicled graft in case I and a free graft in case II. Both patients have recovered smoothly wit out any events and have been doing well postoperatively.

  • Background: Common treatment modalities for tracheal stenosis include conservative methods such as repeated balloon dilatation, removal of obstructive material through bronchoscopy and T-tube insertion as well as operative treatment methods. Recent advances in surgical approaches through tracheal resection and end-to-end anastomosis have been reported to give better functional and anatomical results. Material and Method: Between March 1990 and July 2002, 41 patients who received tracheal resection and end-to-end anastomosis at Asan Medical Center, University of Ulsan were studied retrospectively. Result: The causes for tracheal resection and end-to-end anastomosis included 26 cases of postintubation stenosis, 10 cases of primary tracheal tumors (3 benign, 7 malignant), 1 case of endobronchial tuberculosis, 2 cases of traumatic rupture, and 2 cases of tracheal invasion of a thyroid cancer, Of the 41 patients who received tracheal resection and reconstruction, 29 received tracheal resection and end-to-end anastomosis, and 12 received laryngotracheal anastomosis with cricoid or thyroid cartilage resection. Four of these patients received supralaryngeal release. The average length of the resected trachea was $3.6{\pm}1.0$cm. Of the 41 patients who received tracheal resection and end-to-end anastomosis, 30 (73.2%) experienced no postoperative complications, and 8 (19.5%) experienced granulation tissue growth and/or minor infections which improved after conservative management. Good or satisfactory results were therefore achieved in 92.7%. Complications included repeated granulation tissue growth in 7, wound infection in 2, anastomotic site dehiscence in 2, restenosis resulting in dyspnea on exertion in 1, and repeated postoperative aspiration requiring retracheostomy in 1. There was no early postoperative mortality. There were 3 cases of hospital death. Conclusion: In cases of proper length of tracheal lesion, excellent results were obtained after tracheal resection and end-to-end anastomosis. But, granulation tissue growth is so serious complication, it is necessary for continuous study and efforts to prevent it.

  • Background: Aortopulmonary window (APW) is a very rare congenital heart anomaly, often associated with other cardiac anomalies. It causes a significant systemic to pulmonary artery shunt, which requires early surgical correction. Accurate diagnosis and surgical correction will bring good outcomes. The purpose of this study was to describe our 20-year experience of aortopulmonary window. Material and Method: Between March 1985 and January 2005, 16 patients with APW underwent surgical repair. Mean age at operation was $157.8{\pm}245.3$ ($15.0{\sim}994.0$) days and mean weight was $4.8{\pm}2.5$ ($1.7{\sim}10.7$) kg. Patent ductus arteriosus (8), atrial septal defect (7), interruptedaortic arch (5), ventricular septal defect (4), patent foramen ovate (3), tricuspid valve regurgitation (3), mitral valve regurgitation (2), aortic valve regurgitation (1), coarctation of aorta (1), left superior vena cavae (1), and dextrocardia (1) were associated. Repair methods included 1) division of the APW with primary closure or patch closure of aorta and pulmonary artery primary closure or patch closure (11) and 2) intra-arterial patch closure (3). 3) Division of the window and descending aorta to APW anastomosis (2) in the patients with interrupted aortic arch or coarctation. Result: There was one death. The patient had 2.5 cm long severe tracheal stenosis from carina with tracheal bronchus supplying right upper lobe. The patient died at 5th post operative day due to massive tracheal bleeding. Patients with complex aortopulmonary window had longer intensive care unit and hospital stay and showed more morbidities and higher reoperation rates. 5 patients had reoperations due to left pulmonary artery stenosis (4), right pulmonary artery stenosis (2), and main pulmonary artery stenosis (1). The mean follow-up period was $6.8{\pm}5.6$ (57.0 days$\sim$16.7 years)years and all patients belonged to NYHA class 1. Conclusion: With early and prompt correction of APW, excellent surgical outcome can be expected. However, optimal surgical method needs to be established to decrease the rate of stenosis of pulmonary arteries.
