From Jan. 1983 to June 1984 in Yonsei University Medical College 17 patients received curative resectivesurgery due to bronchogenic carcinoma. The following results were obtained by comparing the CT findings to theoperative and histological findings of those patients. 1. The histological types of 17 cases of bronchogeniccarcinoma were squamous cell Ca. 8 cases, adenocarcinoma 7 cases, and undifferentiated Ca. 2 cases. The both ofthe undifferentiated type were confirmed by post operative histological study. 2. The lesions showing falsepositivity of mediastinal invasion are enlarged but have well circumscribed margins and separated lymph nodes. 3.In contrast, the prediction of hilar infiltration by CT gave only 25% sensitivity, 77.8% specificity and 52.9%accuracy. 4. For the clinical staging done by CT, only 47.1% were in accordance with the surgical staging. 5.However, CT is useful in selecting the patients who need invasive staging before abandoning curative resection andin suggesting the type of invasive staging according to the location of the lesion.

BACKGROUND: There has been a change in the causes of aortic stenosis when comparence of rheumatioc aortic stenosis in recent year. Therefore, we studied the etiology factor of pure aortic stenosis. METHODS: The gross surgical pathologic features of the aortic valves were reviewed in 92 patients with pure aotic stenosis whom underwent aortic valve replacement at Yonsei University, Cardiovascular center between July 1989 and June 1994. RESULTS: The three most frequent causes were 1) calcification of congenital bicuspid valve in 30%, 2) degenerative calcification of aortic valve in 22%, 3) rheumatioc valvular change in 48%. The mean age at the time of aortic valve replacement for the entire series of patients was 54.4 years. The range of age was from 18 years to 77 years. Males predominated for degenerative disease and congenital bicuspid valves, but there were reversed rheumatic origin. One or more complications occured in 17% of patients undergoing operation. The surgical mortality was 3.3%. CONCLUSION: Our data suggest that more common cause of aortic stenosis is non-rheumatic disease rather than rheumatinc origin.
