Tension pneumothorax during one-lung ventilation (OLV) is a rare but life-threatening complication. A 79-year-old male patient who was diagnosed with lung cancer underwent $Univent^{(R)}$ Tube (Fuji Systems Corporation, Tokyo) intubation for left upper lobectomy. Two hours after the initiation of OLV, the patient could not tolerate it. Thus, one-and two-lung ventilation were alternatively applied to continue the operation. After the operation, an emergent chest radiograph was taken, and pneumothorax was found at the right (dependent) lung field.

Intralobar pulmonary sequestration is rare congenital lung disease, in which systemic artery supplies a congenitally cystic portion of the lung. Patient was 19 years old male whose complaints were fever, chest pain and sputum. Chest film showed a round homogenous density and air-fluid level at the left lower lung field and on bronchogram, contrast materials did not enter the abscess pocket. By operation multiple lung abscess pockets at the lower lobe were noted. An aberrant artery, measuring 0.4cm. in diameter and 2 cm. in length, arised from the aorta just above the diaphragm and entered the pusterior basal segment of left lower lobe. After division of the artery, left lower lobectomy was done ana postoperative hospital course was uneventful. Pathologic findings were multiple lung cysts which were not connected to the left lower lobe bronchi and an aberrant artery which showed elastic lamillation and mild sclerotic change.

The Swyer-James syndrome is one of the very few condition that the density of one lung is markedly less than the density of the other and frequently presents a diagnostic problem. In 1989, we reported a case of Swyer-James Syndrome. Recently, we experienced a new case of this syndrome. Left upper lobectomy was performed and postoperative pneumonia was developed, but the patient was recovered.

Sarcoidosis is a granulomatous disease of unknown etiology. It frequently involves thoracic lymph node and pulmonary parenchyme characterized by non-caseating granulomas and varying degrees of fibrosis. We have experienced a pulmonary sarcoidosis in the left lower lobe of the lung in a 40 year old man who underwent left lower lobectomy by video-assisted thoracic surgery.

The purpose of present study is to investigate the significance of preoperative evaluation with perfusion lung scintigraphy in patients with lung cancer. Lung scans with the use of macroaggregated human serum albumin labeled with technetlum-99m were carried out in 35 patients with lung cancer before thoracotomy at Seoul National University Hospital during the period from November 1981 to September 1983. The relationship between size of the perfusion defect as seen by perfusion lung scan and size of the mass lesion as seen radiologically was correlated with the presence of regional adenopathy and resectability. Among patients with a larger perfusion defect than mass lesion on chest X-ray film.86% were found to have regional lymph node involvement with 29% resectability, whereas among patients in whom a larger defect was not present only 14% had such extension of the disease with 93% resectability. The relative pulmonary arterial perfusion of affected lung was calculated from the counts of radioactivity recorded from affected lung on both anterior and posterior scans expressed as a percentage of the total counts in the scan. The mean relative pulmonary arterial perfusion of the inoperable group [34\ulcorner%] is significantly different from both that of the pneumonectomy group [39\ulcorner%] and that of the lobectomy group [48\ulcorner%].(p<0.01)

A 7 years old, male, Afghan hound (case 1) and a 10 years old, castrated male, Pekingese (case 2) were referred with dyspnea. In case 1, thoracic radiographs showed moderate amount of pleural effusion and lobar sign in the left cranial lung lobe. Following computed tomographic (CT) examination, lung lobe torsion in left cranial lung lobe was diagnosed. In case 2, thoracic radiographs showed increased cranial lobar opacity but there was no evidence of pleural effusion. CT examination revealed an abrupt ending bronchus in the left cranial lung lobe. Based on the imaging diagnosis, left cranial lung lobectomy was performed in both cases. Case 1 showed increased lobar opacity and pleural effusion, while case 2 just showed less concrete evidence of lung lobe torsion on thoracic radiographs and marked severe chronic suppurative pneumonia was histopathologically confirmed. In conclusion, CT could be an important modality when atypical lung disease is suspicious.

Objective: To determine the effects of respiration on the size of lung cysts by comparing inspiratory and expiratory high-resolution CT (HRCT) scans. Materials and Methods: The authors evaluated the size of cystic lesions, as seen on paired inspiratory and expiratory HRCT scans, in 54 patients with Langerhans cell histiocytosis (n = 3), pulmonary lymphangiomyomatosis (n = 4), confluent centrilobular emphysema (n = 9), paraseptal emphysema and bullae (n = 16), cystic bronchiectasis (n = 13), and honeycombing (n = 9). Using paired inspiratory and expiratory HRCT scans obtained at the corresponding anatomic level, a total of 270 cystic lesions were selected simultaneously on the basis of five lesions per lung disease. Changes in lung cyst size observed during respiration were assessed by two radiologists. In a limited number of cases (n = 11), pathologic specimens were obtained by open lung biopsy or lobectomy. Results: All cystic lesions in patients with Langerhans cell histiocytosis, lymphangiomyomatosis, cystic bronchiectasis, honeycombing, and confluent centrilobular emphysema became smaller on expiration, but in two cases of paraseptal emphysema and bullae there was no change. Conclusion: In cases in which expiratory CT scans indicate that cysts have become smaller, cystic lesions may communicate with the airways. To determine whether, for cysts and cystic lesions, this connection does in fact exist, paired inspiratory and expiratory HRCT scans are necessary.

A total of 129 patients with a confirmed diagnosis of primary lung cancer were treated at Dep. of Thoracic k Cardiovascular Surgery, National Medical Center, Seoul, Korea, between July, 1981 and Dec., 1988. Particular emphasis was given in this review to the 72 patients that underwent surgical resection of their primary lung lesion. Factors such as histology, type of resection, sex, age, staging, and degree of dissemination were considered possible influences on survival. The age group of fifty k sixty decade occupied 55.8 %, and the youngest being 24 years and oldest 78 years. The incidence ratio of male to female was 3,2:1. The subjective symptoms of the patients were coughing [72.6%], chest pain [48.2%] and hemoptysis [35.6%], which were due to primary local influence. The confirmed diagnostic procedures were bronchoscopic biopsy, sputum cytology needle aspiration biopsy, open lung biopsy, anterior mediastinotomy & lymph node biopsy. By pathologic classifications, the squamous cell carcinoma was the most prevalent, 67 cases [51.9 %], and the adenocarcinoma in 36 cases [27.9%], undifferentiated small cell carcinoma in 13 cases [10.1 %], undifferentiated large cell carcinoma in 9 cases [6.9%], bronchioloalveolar carcinoma was 4 cases [3.1%]. The lymph node dissection with pneumonectomy [42 cases], lobectomy [14 cases] and pneumonectomy [6 cases], lobectomy [9 cases] without lymph node dissection were performed. The post operative TNM Staging[AJC] in 72 cases were Stage I in 24 cases, Stage II in 27 cases, and Stage III in 21 cases. Overall resectable was possible in 72 cases [55.8 %], and the operation mortality was 5.6 % [4 cases].

This is a case report of surgical management of a bilateral intralobar pulmonary sequestration with horseshoe lung presenting with frequent U I with productive sputum. Simple chest X-ray showed pneumonic consolidation and infiltration on both lower lobes, and chest CT revealed multiple cystic lesions compatible with pulmonary sequestration. The aortography demonstrated two anomalous systemic arteries arising from the thoracic aorta just above the diaphragm to both sequestrums. Left lower lobectomy was performed through the left thoracotomy with ligations and divisions of the both systemic feeding arteries to the left and right sequestrum, and division of the isthmic portion of horseshoe lung without removal of right sequestrum. The patient was discharged on the postoperative loth day and followed-up till now without any sequelae and symptoms of residual right sequestration. The recent follow-up chest CT 5 months after the operation revealed spontaneous regression of the residual right sequestrum. Authors would suggested that only division of aberrant artery to sequestrum without lobectomy may be applied in uncomplicated ca e of intrapulmonary seqilestration.
