A 7-year-old castrated male Pomeranian dog presented with severe goose honking cough and dyspnea. Thoracic radiographs revealed a narrowed tracheal diameter at the thoracic inlet, classified as tracheal collapse grade 4. Despite medical treatment, the dog's life-threatening airway obstruction did not improve. Subsequently, tracheal stent placement resulted in a significant improvement in respiratory condition, with no recurrence of symptoms observed during the 4-month period, except for coughing induced by excitement and anxiety. However, the patient presented with a one-week history of productive cough, exercise intolerance, and loss of appetite. Radiographs and computed tomography scans revealed torsion of the left cranial lung lobe. The patient underwent affected lung lobectomy, which involved the removal of the necrotized cranial portion and heavily congested caudal portion. Unfortunately, the patient did not recover and eventually passed away. Histopathological examination of the resected lung tissue confirmed coagulative necrosis and marked peribronchiolar edema, consistent with lung lobe torsion.

We observed 56 cases of nontraumatic pneumothorax clinically and statistically, which had been experienced at the deparment of chest surgery. St. Mary`s Hospital,Catholic Medical College in theserecent years. 1] In the underlying pathology of spontaneous pneumothorax, nontuberculous origin [60.7%], especially due to pulmonary emphysema or blebs[17.8%], especially due to pulmonary emphysema or blebs[17. 8%], tended to increase as the reports of foreign countries, but tuberculous origin was still high in our country[39.3%]. Considering the 14 cases, unknown underlying pathology, the most of them might have scattered blebs which were not revealed in chest Roentgen films. 2] The principle treatment done in our clinic was as follows; The patients, below 20% lung collapse were treated by bed rest and abdominal respiration. The patients, between 20% and 40% lung collapse were treated by repeated pleural aspiration or closed thoracotomy followed. The cases,over 40% lung collapse were treated by closed thoracotomy initially. 3] The average duration of indweIling catheter was 3 to 4 days in the closed thoracotomy. We used to not remove the indwelling catheter early to promote pleural adhesion. 4] Sometimes, the closed thoracotomy drainage induces bronchial irritation and asthmatic attacks, especially in old age group accompanying pulmonary emphysema. In these cases, respiratory difficulties and acidosis should be prevented and controlled with medical treatment including steroid therapy.

Reexpansion pulmonary edema is a rare complication of the treatment of lung collapse secondary to pneumothorax, pleural effusion, or atelectasis. But occasionally, severe morbidity and death may result. Reexpansion pulmonary edema occurs when chronically collapsed lung is rapidly reexpanded by evacuation of large amounts of air or fluid. In the treatment of the chronically collapsed lung, physicians must remember the possible events and prevent the complications. When the difference in airway resistance or lung compliance between the two lungs is exaggerated, conventional mechanical ventilation might lead to preferential ventilation with hyperexpansion of one lung and gradual collapse of the other. Differential ventilation has been advocated to avert this problem. By differential lung ventilation, we successfully treated a severe reexpansion pulmonary edema in two patients. Therefore we suggest that differential lung ventilation is the treatment of choice for severe reexpansion pulmonary edema.

Pregnancy induces many physiologic changes, and it can cause hemoptysis in relation to the underlying or potential pulmonary diseases. Although hemoptysis is not a frequent event during pregnancy, a thorough search for its etiology and then immediate management should be initiated for a case of massive hemoptysis to avoid serious adverse effects on both the fetus and the mother. Most hemoptysis events during pregnancy are related to well known etiologies, but there are a few reported cases of hemoptysis in pregnant women who are without any underlying lung lesion. We report here on a case of a pregnant woman with total lung collapse due to hemoptysis, and a thorough search for the etiology after delivery could not reveal any etiology.

Reexpansion pulmonary edema following pneumothorax, atelectasis, massive pleural effusion are clinically uncommon, but sometimes life threatening progression. Reexpansion pulmonary edema is usually ipsilateral but rarely contralateral or both. Reexpansion pulmonary edema was occurred when chronically collapsed lung is rapidly reexpanded by evacuation of large amounts of air or fluid. The pathogenesis of the reexpansion pulmonary edema is unknown but is probably mutifactorial. The etiological factors of the reexpansion pulmonary edema are chronicity of the lung collapse, technique of the reexpansion, airway obstruction, loss of the surfactant, and pulmonary artery pressure changes. In the treatment of the chronically collapsed lung, physician must be remembered the possible events, and to prevent of the complication.

Reexpansion pulmonary edema[ RPE ] with hypoxemia and hypotension is a very rare complication of the treatment of lung collapse secondary to pneumothorax and pleural effusion. We experienced two cases of RPE. One is a 29 year old male with complete right pneumothorax and the other is a 20 year old female with massive right pleural effusion. Life threatening pulmonary edema was developed soon after insertion of chest tube in both. Fortunately, RPE was detected early and intensive treatment was performed. They were discharged without complication. Although RPE with hypoxemia and hypotension is rare , it is very serious and occasionally life-threatening. So, chest surgeon treating lung collapse must be aware of the possibility of RPE and make an effort to prevent the occurence of this condition.

Re-expansion pulmonary edema following pneumothorax or hemothorax is clinically uncommon but occasionally life threatening. Clinical details are given of two patients.Ipsilateral pulmonary edema were developed after chest tube insertion due to spontaneous pneumothorax in case I and after evacuation of postoperative hemothorax in case II. The patients were treated with frequent bronchial toilet.The administration of colloid solution and diuretics was effective. The possible mechanisms underlying the edema are discussed.Both increased time of collapse and suction tended to correlate with reexpansion edema.The present two cases provided evidence for longstanding lung collapse and immediate application of suction.

An unusual placentoid bullous lesion of the lung was reported. The patient was a 27-year- old woman with a 1-week history of chest pain and mild dyspnea. Chest radiographic studies showed multiple huge bullae in right upper lobe and variable-sized bullae in middle and lower lobes with collapse. She underwent right pneumonectomy with preoperative impression of bullous lung disease and emphysema. Histopathologically, the most distinctive features were villous structures within bullous airspace, which resembled placetal villi with degeneration.

Children`s small airway precludes the use of standard methods of bronchial separation. So, we performed the posterior thoracotomy under the prone position in 3 cases to avoid endobronchial gravity spillage of secretion and infected debris from the diseased lung to the contralateral sound lung. The advantages of the posterior thoracotomy under the prone position was discussed. In two cases, empyema with total collapse of left lung and congenital cystic adenomatoid malformation [CCAM] of right lung, copious secretion was spilled through the endotracheal tube but could be removed successfully by the endotracheal suction. In the third case of bilateral peripleural abscess, bilateral posterior thoractomy was done without position change. All procedures were performed without any technical difficulty and complication.

Objective: To describe the radiologic findings of migrating lobar atelectasis of the right lung. Materials and Methods: Chest radiographs (n = 6) and CT scans (n = 5) of six patients with migrating lobar atelectasis of the right lung were analyzed retrospectively. The underlying diseases associated with lobar atelectasis were bronchogenic carcinoma (n = 4), bronchial tuberculosis (n = 1), and tracheobronchial amyloidosis (n = 1). Results: Atelectasis involved the right upper lobe (RUL) (n = 3) and both the RUL and right middle lobe (RML) (n = 3). On supine anteroposterior radiographs (n = 5) and on an erect posteroanterior radiograph (n = 1), the atelectatic lobe(s) occupied the right upper lung zone, with a wedge shape abutting onto the right mediastinal border. On erect posteroanterior radiographs (n = 6), the heavy atelectatic lobe(s) migrated downward, forming a peri- or infrahilar area of increased opacity and obscuring the right cardiac margin. Erect lateral radiographs (n = 4) showed inferior shift of the anterosuperiorly located atelectatic lobe(s) to the anteroinferior portion of the hemithorax. Conclusion: Atelectatic lobe(s) can move within the hemithorax according to changes in a patient s position. This process involves the RUL or both the RUL and RML.
