We report a rare cause of lung cavities, occurring in a patient with intrapulmonary cystic teratoma. Computed tomography (CT) provided us more detailed informations about the tumor characteristics containing fat and calcification, which could not be distinguished on the plain radiographs. In addition, CTscans clearly demonstrated the dilated anterior segmental bronchus of the left upper lobe entering the posterior aspect of the cavity.

Awareness of anatomical variations in lungs is essential during segmental or lobar resections of lungs. We studied the variations of fissures, lobes and hilar structures in 65 right and 73 left isolated lungs from the dissection hall. Horizontal fissure was absent in 3.07% and incomplete in 35.38% of right lungs. Four point six one percentage of right lungs had 3 fissures and 4 lobes. Three point zero seven percentage of right lungs had 3 arteries, 67.69% had 2 arteries, and 29.23% had only one artery in the hilum. Sixty-three point zero seven percentage of right lungs had two veins in the hilum; 32.30% had 3 veins in the hilum; and 4.61% had more than 3 veins in the hilum. Ninety-eight point four six percentage of right lungs showed 2 bronchi in the hilum, and 1.53% of them showed 3 bronchi in the hilum. Two of the right lungs (3.07%) had an artery passing across the oblique fissure. Fifteen point zero six percentage of left lungs showed incomplete oblique fissure and 2.73% showed 2 fissures and 3 lobes. Five point four seven percentage of left lungs showed 2 arteries and 94.52% had only one artery in the hilum. Eighty point eight two percentage of left lungs had two veins in the hilum and 19.17% had 3 veins in the hilum. Twenty-one point nine one percent of left lungs had 2 bronchi and 78.08% had only one bronchus in the hilum. The knowledge of variations in the lobar and hilar anatomy of the lung presented in this study is clinically important while interpreting the radiological images and performing surgical procedures.

Tracheal bronchus is a congenital anomaly usually originating from the right lateral wall of the trachea. It is usually found within 2 cm above the carina. Most cases of tracheal bronchus are asymptomatic and detected only incidentally on bronchoscopy or radiologic examination. Anatomic abnormalities of the airway are particular concern to anesthesiologists. We report a case in which an undiagnosed tracheal bronchus interfered with isolation of the right lung with a single lumen tube with bronchial blocker (Univent tube). Bronchoscopic examination showed the presence of an opening approximately 0.5 cm proximal to the carina. We withdrew the Univent tube and replaced it with a left-sided, 37 F double-lumen endotracheal tube. Right lung isolation was done satisfactorily and allowed the completion of the procedure.

We have experienced two cases of one lung anesthesia using univent tube for thoracie surgery. One was the bronchoplasty of the right upper lobe. The other was the left pneumonectomy. The movable endobronchial blocker was introduced into the aimed main bronchus applying the "tube rotation method", In the case of brochoplasty, arterial hypoxemia and hypercarbia has not been corrected well because of the partial obstruction of the carina by endobronchial blocker, but the neurologic complications due to these problems were not encountered. No significant problem has been encountered in the pneumonectomy case. Compared with the standard technique using a double lumen endobronchial tube, this method is simple, easy, effective and less traumatous.

PURPOSE: To determine the CT factors which predict positive results of bronchoscopic biopsy in cases of lung cancer with CT-bronchus sign. MATERIALS AND METHODS: In 30 patients who on CT showed a lung mass with CT-bronchus sign and who had undergone bronchoscopic biopsy, lung cancer was confirmed histopathologically and/or clinically. The CT findings were evaluated for the location, nature and size of the mass, and the type of CT-bronchus sign, and the diagnostic rate of bronchoscopic biopsy and of CT findings was compared. RESULTS: Seventeen of 30 patients (56.7%) were diagnosed by bronchoscopic biopsy and their diagnostic rates according to the location were as follows: 100% (10/10) in cases involving the lobar bronchus; 60% (6/10) in cases involving the proximal segmental bronchus and 10% (1/10) in cases involving the distal segmental bronchus. In 20 cases of peripheral lung cancer, 16.7% (1/6) of masses with less than 3cm in diameter, 44.4% (4/9) of masses with more than 3cm and less than 6cm, and 40.0% (2/5) of masses with more than 6cm were diagnosed bronchoscopically. In addition, 57.1% (4/7) of cases with abrupt bronchial obstruction, 33.3% (3/9) with a patent bronchus within the mass, 0% (0/3) with bronchial displacement or a marginally located bronchus and 0% (0/1) with tapered bronchial obstruction were diagnosed on bronchoscopic biopsy. One of two cases with perilesional lymphangitic spread and two of four cases with a large cavity were diagnosed bronchoscopically. CONCLUSION: In cases of lung cancer, bronchoscopic biopsy is a useful initial diagnostic method where the mass is located in 1cm proximal to segmental bronchial bifurcation and is more than 3cm in diameter, there is CT-bronchus sign with abrupt bronchial obstruction or a patent bronchus within the mass, and associated perilesional lymphangitic spread or large air-cavity. In most cases where there is peripheral lung mass less than 3cm in diameter, however, bronchoscopic biopsy alone is not adequate, and the use of a further diagnostic modality is required.

An accessory cardiac bronchus (ACB) is a rare congenital anomaly of the trachobronchial tree. It rarely presents with symptoms, and is usually diagnosed incidentally by chest CT, bronchoscopy, or during surgery. We experienced a case of accessory cardiac bronchus found incidentally in the bronchus intermedius with lung cancer in the right lower lobe, and surgically removed.

A method for one-lung anesthesia has been developed in which Fogarty occiusion catheter is used to produce endobronchial blockade. It eliminates most of the problems which occur with the standard technique using a doublelumen cuffed endobronchial tube. No significant problem has been endobronchial tube. No significant problem has been encountered in this bronchoplasty case. This method is so simple and effective. A standard endotracheal tube was introduced, and a Fogarty catheter was inserted through the endotracheal tube to the desired main bronchus just before the left abnormal bronchus was open. After opening the bronchus, the Fogarty catheter could be placed in the appropriate location by sight. Once one-lung ventilation was no longer necessary, the Fogarty catheter could be deflated without distrubing the endotracheal tube.

Tracheal bronchus (TB) is an aberrant, accessary or ectopic bronchus arising almost exclusively from the right side of the tracheal wall above the carina. In our center, 673 bronchoscopic examinations were performed from 2009 to 2011 in patients undergoing one lung ventilation (OLV) and 3 TB were found. The incidence of a TB at bronchoscopy was 0.45% in our research, which is consistent with the reported incidence range from 0.1-5%. The clinician should consider the possibility of anomalous right upper lobe bronchus and perform bronchoscopy prior to the right bronchial blocker insertion, when left-sided OLV using bronchial blocker is planned. Also, for the patient with TB, a double lumen tube insertion is recommended than a blocker insertion to achieve OLV completely.

A bronchial obstruction of the remaining lung is a rare complication of thoracic surgery. We report a case of this rare complication after a right upper lobectomy due to a giant bulla. Post-resectional angulation of the bronchus intermedius caused the bronchial obstruction. An intrabronchial stent was inserted into the bronchus intermedius, which relieved the obstruction.
