Metastasizing Pleomorphic Adenoma in Right Lung: A case report / 대한흉부외과학회지

A metastasizing pleomorphic adenoma originating from the parotid gland is a rare form of neoplasm. The neoplasm is a histologically benign, but clinically controversial entity. Herein, a case report of a pleuro-pneumonectomy of a metastasizing pleomorphic adenoma in the right lung is described. A 57-year-old man, who underwent resection of parotid gland due to a pleomorphic adenoma, presented with multiple metastases on the right lung, mediastinum, pericardium and intercostal muscle. The metastatic lesions were composed of a benign pleomorphic structure.

Right Pulmonary Artery Agenesis: A case report / 대한흉부외과학회지

Unilateral pulmonary artery agenesis is a rare congenital malformation usually associated with other cardiovascular anomaly such as Tetralogy of Fallot. Isolated pulmonary artery agenesis is very rare, and usually asymptomatic. It is usually highly suspected by routine chest X-ray, and associated symptoms are hemoptysis, blood tinged sputum, repeated pulmonary infection, and dyspnea on exertion. We have recently experienced the right pulmonary artery agenesis in 27 year-old male patient, complaining of minimal hemoptysis and sustained blood tinged sputum. He was successfully treated by right pneumonectomy, so we report this case with the review of associated literature.

Analysis of Postoperative Coronary Angiography in Symptomatic Patients / 대한흉부외과학회지

BACKGROUND: We analyzed post-operative angiography performed in symptomatic patients to evaluate the patency rates and the roles of grafts. MATERIAL AND METHOD: We reviewed 52 (15%) coronary angiograms performed for recurrent angina after prior coronary artery bypass surgery from January 1995 to June 2005. A total of 345 patients underwent coronary artery bypass surgery during this period. There were 41 men and 11 women and the mean age was 64.07+/-15.58 years. The median period from operation to re-angiogram was 68.5 months (range, 1 to 126 months). The numbers of grafts and peripheral anastomoses were 42 and 43 for internal thoracic artery (ITA), 14 and 20 for radial artery (RA), and 49 and 89 for saphenous vein. The mean number of anastomosis was 2.9 per patient. RESULT: The patency rates of ITA, RA and saphenous vein graft (SVG) were 37/43 (86%), 17/20 (85%) and 34/89 (38.2%). The patency rate of arterial grafts was significantly higher than that of SVG (p<0.001) and the patency rate of the RA was comparable to that of ITA (p=0.912). The patency rate of sequential SVGs was higher than that of single SVG (40.3% vs 31.8%, p=0.478) and the patency rate of proximal segments in sequential anastomosis was higher than that in single anastomsis (55.6% vs 31.8%, p=0.097), but statistically not significant. CONCLUSION: Arterial grafts have markedly superior patency rates than SVGs, so consideration should be given to the vigorous use of arterial grafts. The patency rate of the RA was comparable to that of ITA.
