Background and Objectives： Vegetable Foreign bodies (VFB) in the bronchial tree may be complicated by fragmentation, slippage and impaction during the removal with forceps. This study is to evaluate the safety and efficacy for the technique of removing VFB from the bronchial tree in infants and early childhood using Fogarty balloon catheter. Materials and methods : The subjects consisted of 18 infants and early childhood (7-22 months old) with VFB in the bronchial tree from January 1991 through October 1998. The authors first attempted removal of VFB with forceps and if that failed, removed VFB with Fogarty arterial embolectomy catheter under the ventilating bronchoscopy and general anesthesia. Results: We removed 6 VFB with forceps. could not remove anymore, and so removed 12 VFB with Fogarty catheter. In 8 VFB of less than 24 hours, we could remove 6 VFB with forceps and 2 VFB which could not be removed with forceps were removed with Fogarty catheter. In 10 VFB of more than 24 hours, we could not remove with forceps and removed with Fogarty catheter. Conclusions : VFB in the bronchial tree of infants and early childhood can usually be removed with forceps. But we think that Fogarty balloon catheter technique is a easy, safe method for the removal of bronchial VFB of more than 24 hours, fragmentation, impaction, lower bronchus and too round or slippery to remove with forceps in infants and early childhood.

This study was conducted to observe the condition of the ramifications of the bronchus and pulmonary blood vascular system by injecting the vinylite into the bronchial tree and pulmonary blood vessels in 100 normal adult dogs. The results obtained were summarized as follows: 1. Lungs of dog were composed of the same pulmonary territories as in lungs of human. 2. Cardiac lobe corresponding to R.medio-bassalis of human lungs was well developed and situated as a independent cardiac lobe, in ventral side of right lung. 3. Bronchial tree were in the patterns of axial divergency and blood vascular systems were (in general) branched along the bronchial tree, arteries lying near the bronchial tree but veins apart from it. 4. Among the branching patterns of bronchus pulmonary artery and pulmonary vein in each lobe, the type presented most frequently were noted, which were designated basic type by the author. 5. Pulmonary blood vessels were not always branched in accordance with bronchial tree, diverged inmore complex patterns, especially in venous vascular system. 6. Ramus anterior (lobe apicalis) was always observed in all casting specimen. 7. There was a case of peculiar variation patterns of the ramification in the bronchi directing into the left apical and cardiac lobe, arose respectivelly, at independent origin of bifurcation in the left bronchial stem, and a case of peculiar variation pattern of the artery entering left apical lobe and cardiac lobe, had a same origin of the bifurcation at rami pulmonary artery, and then divided respectivelly into the rami medi artery and rami left apical lobe artery. 8. In the classification based on the patterns of bronchial and blood vasculor divergencys, there were a lot of significant combination cases in their patterns.

Adenoid cystic carcinoma arising from the submucosal glands of the trachea and bronchial tree is rare. The histopathology and natural history of bronchial adenoid cystic carcinoma have been well documented, but detailed descriptions of its cytomorphology are few. We report a case of primary bronchial adenoid cystic carcinoma in a 20-year-old female, diagnosed by bronchial brushing cytology. The cytologic specimens showed large clusters of small cells arranged around cystlike spaces containing globular basophilic material.

Asthma is a disease of the airways that is characterized by increased responsiveness of the tracheobronchial tree to a multiplicity of stimuli. A number of causes have been postulated for the increased airway reactivity of asthma is conservative as beta-adrenergic agonist, methylxanthines, glucocorticoids, anticholinergics and mast cell stabilizing agent. Stellate ganglion block for the treatment of bronchial asthma has its controversies. Stellate ganglion block was performed for the treatment of 3 patients with bronchial asthma. After stellate ganglion blocks, dyspnea, coughing and wheezing was markedly reduced. Lung function test improved with 1 st case. Two asthma cases were able to discontinue medication for asthma. No severe aggrevation of bronchial symptoms were noted after stellate ganglion blocks. It suggested that stellate ganglion block can be safely performed on bronchial asthmatic patients.

Traumatic rupture of the main bronchus is comparatively very rare. With the advent of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. Rupture of the bronchus is an unusual result of nonpenetrating trauma to the chest. Early recognition of bronchial rupture and emergency thoracotomy and management is essential for reducing of morbidity, mortality and late complications. We experienced 3 cases of bronchial rupture caused by nonpenetrating chest trauma with or without rib fracture. Patients were suffered from dyspnea and chest pain. After closed thoracostomy, corrective surgery was performed. Postoperative courses were uneventful and discharged without any complication.

Massive hemoptysis, usually rapid flooding of tracheobronchial tree and asphyxia, is associated with high mortality. We have controlled massive hemoptysis in two cases with use of bronchial artery angiography & selective bronchial artery embolization with Gelfoam particle. One case was inoperable case that was confirmed as TOF c severe pulmonary artery hypoplasia with massive hemoptysis due to hypertrophied bronchial artery and its collaterals. Another case was congenital ASD with pulmonary Aspergillosis, postop. empyema and BPF associated with massive bleeding due to erosion of hypervascular bronchial artery. We experienced dramatic improvement of general condition and cessation of massive hemoptysis for above two cases. No other problems and complication were noted during postop. hospitalization and follow-up period.

This study was conducted to observe the condition of the ramification of the bronchus and pulmonary blood vascular system by injection of vinylite into the bronchial tree and pulmonary blood vessels in normal adult swines. The results obtained were summarized as follows. 1. Lungs of swine were composed of the same pulmonary territories as in lungs of human and dog. 2. Bronchial tree of swine also were axial divergency in the patterns. 3. Ramification of the left and right apical lobes are especially complex patterns but cardiac and diaphragmatic lobes are a little monotonous. 4. Intermediate lobe corresponding to mediobasalis branch of human lungs formed only one lobe in swine lung. 5. Pulmonary artery of right apical lobe was mono branch form in all case by authors observation. 6. $B._2$ streched into the seg. dorsalis of the right apical lobe was especially developed compare to $B._1$, $B._3$ of the seg, apicalis and seg, ventralis.

The incidence of traumatic rupture of the tracheobronchial tree has been increased considerably with advent of widespread mechanization and high speed era. Rupture of the bronchus is an unusual result of nonpenetrating trauma to chest. Early diagnosis and primary repair not only restore normal lung function but also avoid difficulties and complications associated with delayed diagnosis and repair. These complications are pneumonia, atelectasis and lung abscess secondary to the bronchial obtruction. We experienced a case of partial rupture on left main bronchus caused by nonpenetrating blunt chest trauma with rib fractures 1 year ago. He was suffered from progressively developing dyspnea on exercise and treated as bronchial asthma at other hospital. Bronchoscopic finding was the narrowed lumen of left main bronchus at 1cm from carina by web-like membrane. We confirmed by bronchogram and repaired by end to end anastomosis, which is rare delayed finding in bronchial rupture without pulmonary complications. We report a case of nonpenetrating traumatic bronchial rupture, manifested by bronchial web in bronchoscopy.

In this paper, we investigate the potential for retrieval of morphometric data from three dimensional images of conducting bronchus obtained by X-ray Computerized Tomography (CT) and to explore the potential for the use of rapid prototype machine to produce physical hollow bronchus casts for mathematical modeling and experimental verification of particle deposition models. We segment the bronchus of lung by mathematical morphology method from obtained images by CT. The surface data representing volumetric bronchus data in three dimensions are converted to STL(streolithography) file and three dimensional solid model is created by using input STL file and rapid prototype machine. Two physical hollow cast models are created from the CT images of bronchial tree phantom and living human bronchus. We evaluate the usefulness of the rapid prototype model of bronchial tree by comparing diameters of the cross sectional area bronchus segments of the original CT images and the rapid prototyping-derived models imaged by X-ray CT.

Granular cell tumor(GCT) of tracheobronchial tree is a rare neoplasm comprising approximately 6-10% of all GCT and about 1.6% of all benign tumors of the tracheobronchial tree. Since the first observation of GCT in the bronchus by Kramer in the late 1930s, less than 100 cases have been reported in tracheobronchial tree, and probably no such case have been published in Korea yet. Here we report an experience concerning 53 year-old women with an active pulmonary tuberculosis, who also was diagnosed to have a bronchial GCT on bronchoscopy and immunohistochemistry of the specimens.
