Bronchial Atresia Associated with Spontaneous Pneumothorax : Report of A Case

A 32-yr-old male patient with recurrent pneumothorax associated with bronchial atresia of the subsegmental branch of the posterior segmental bronchus of the right upper lobe was successfully treated with right upper lobectomy. Before surgery, the bronchial atresia with pneumothorax was suspected on the chest radiograph and CT scans, which showed the findings of bronchocele with localized hyperinflation of the right upper lobe. The examination of surgical specimen from the resected right upper lobe suggests that the cause of the recurrent pneumothorax was the rupture of the subpleural bullae in the hyperinflated lung segment distal to the atretic bronchus.

Use of Undiluted Potassium Solution in Intermittent Antegrade Warm Blood Cardioplegia (IAWBC) / 대한흉부외과학회지

BACKGROUND: Dilution of blood cardioplegia is not needed in IAWBC as it is in cold blood cardioplegia because it does not aggregate red blood cells on normal body temperature and does not compromise micro coronary circulation. This study was designed to evaluate the safety and efficacy of undiluted potassium solution in IAWBC. MATERIAL AND METHOD: Thirty patients who underwent CABG with IAWBC were grouped into dilutedplegia (n=14) and microplegia (n=16). Potassium was delivered conventionally with 4:1 delivery kit in the dilutedplegia group. The undiluted potassium was directly connected on the blood of oxygenator in the microplegia group. RESULT: There were no differences in sex, age, left ventricular ejection fraction, number of grafts, aortic cross clamping time, and the value of perioperative myocardial enzyme between the two groups. There were no perioperative myocardial infarction and hospital mortality. The amount of crystalloid cardioplegia was 1346+/-597 mL in dilutedplegia (mean+/-standard deviation, and 28+/-9 mL in microplegia (p0.05). 11 patients in dilultedplegia received blood transfusion, but 4 patients in microplegia received blood transfusion (p<0.05). The amount of urine and hemofiltration during the operation were more in dilutedplegia (1250+/-810 mL, 1689+/-548 mL) than in microplegia (959+/-410 mL, 1481+/-784 mL; p<0.05). CONCLUSION: The undiluted potassium of IAWBC in CABG operation is a safe, effective technique for myocardial protection to prevent fluid overload, and blood transfusion. There is no need to use the delivery kit.

Surgical Treatment of Multiple Lung Abscesses with Adenoid Cystic Carcinoma / 대한흉부외과학회지

Adenoid cystic carcinoma is a very slowly growing and directly invasive cancer. The treatment of choice is complete surgical resection but if major complications associated with remaining carcinoma occur, aggressive conservative treatment to prevent complication is able to gain long term survival even though remaining carcinoma metastases to other organs. We experienced a case of surgical treatment of uncontrollable fever that caused by multiple lung abscesses due to obstruction of left main bronchus with adenoid cystic carcinoma. The post operative course was uneventful for 4 months to now.

Synchronous Primary Lung Cancer with Differrent Squamous cell Carcinoma: One Case Report / 대한흉부외과학회지

The synchronous primary lung cancer is very rare cancer, proportion of synchronous lung cancer is about 1~2% of total lung cancer, When pathologic type is same, preoperative diagnosis is very difficult and it may be misdiagnosed as lung to lung metastasis. We have experienced synchronous primary lung cancer of heterogenous squamous cell carcinoma.
