Abstract

Although there is a controversy on the optimal timing for active infective endocarditis(IE), recently good results of early surgical intervention have been published. Herein, we analyzed the results of surgery for active IE according to the duration of preoperative antibiotic treatment. Material and Method : Retrospectively, we analyzed 51 patients who underwent operation for active IE at the department of thoracic and cardiovascular surgery of Samsung medical center from Mar. 1995 to Oct. 2001. Male to female ratio was 39:12, mean age of the patients was 44.5$\pm$17.8 years(range : 13~74). Infected valves were mitral valve in 17(33.3%), aortic valve in 15(29.4%), mitral and aortic valve in 12(23.5), and tricuspid valve in 5(9.8%) cases. Among them, prosthetic valve endocarditis was present in 10(19.6%) cases. Infecting organism was Staphylococcus in 19(37.3%), Streptococcus in 17(33.3%), Enterococcus in 3(5.9%), fungus in 3(5.9%), and other bacteria in 5(9.8%) cases. Organism was not isolated in 6(11.8%) cases, and two organisms were isolated in 4(7.8%) cases. Dividing these patients into two groups according to the duration of preoperative antibiotic treatment(A: less than 7 days, B: more than 8 days), we compared the surgical results between the two groups. Result : There were 16 cases in group A and 35 in group B. Annular reconstruction was performed in 10(62.5%) cases in group A and 10(28.6%) cases in group B, which has statistically significance(p＜0.05). There was one early death in group B. Forty nine patients(96.1%) except two were followed up with mean follow-up duration of 28.7 $\pm$ 23.6 months. Endocarditis was recurred in one in group A, and two in group B. Three late deaths occurred in group B. Recurrence rate and survival were not statistically different between the two groups. Conclusion : Early surgery for active IE showed good results as the result of that which was performed after prolonged antibiotic treatment; therefore, we believe that early surgery for active If could effectively eradicate the infection.

활동성 심내막염의 외과적 치료시기에 대해서는 아직 논란의 여지가 있지만 최근에는 조기 수술에 대한 좋은 보고들이 있다. 이에 저자들은 활동성 심내막염에 대한 수술 결과를 수술 전 항생제 사용기간에 따라 분석해 보았다. 대상 및 방법 : 1995년 3월부터 2001년 10월까지 활동성 심내막염으로 삼성서울병원 흉부외과에서 수술 받은 환자 51명에 대해서 후향적으로 분석을 하였다 남녀 성비는 39 : 12였고, 평균 연령은 44.5$\pm$17.8세(범위 13~74세)였다. 감염된 판막은 승모판막이 17례(33.3%), 대동맥판막이 15례(29.4%), 승모판막 및 대동맥 판막이 12례(23.5%), 삼첨판막이 5례(9.8%)였다. 그 중 인공판막 심내막염이 10례(19.6%)였다. 감염 균주는 포도상구균이 19례(37.3%), 연쇄상구균이 17례(33.3%), 장내구균이 3례(5.9%), 진균이 3례(5.9%), 기타균이 5례(9.8%), 균주가 동정되지 않은 경우가 6례(11.8%)였으며, 4례(7.8%)에서는 2가지 균주가 동정되었다. 이 환자들을 수술 전 항생제 사용기간에 따라 2군으로(A : 7일 이하, B : 8일 이상) 나누어 두 군간의 수술 성적을 비교하였다. 결과 : A군은 16명이었으며 B군은 35명이었다. 판막륜 재건을 A군에서는 10례(62.5%), B군에서 10례(28.6%)로 통계적으로 유의한 차이가 있었다(p ＜ 0.05). 수술 후 조기 사망은 B에서 1례 있었다. 2명을 제외한 49명(96.1%)의 환자에서 추적관찰이 이루어졌으며, 평균 추적관찰 기간은 28.7 $\pm$ 23.6개월로 재발은 A군에서 1례, B군에서 2례 있었다. 만기 사망은 B군에서 3례에서 있었다. 재발률과 생존율 모두 두 군에서 통계적으로 유의한 차이가 없었다. 결론 : 활동성 심내막염에서 조기 수술하는 경우도 수술 전항생제를 충분히 사용한 경우와 비슷한 좋은 결과를 보여 활동성 심내막염의 조기 외과적 치료가 효과적으로 감염을 제거할 수 있다고 사료된다.
