Abstract

Preoperative and postoperative evaluation was done in 60 adult patients above 20 years of age among 152 patients, who had operation for the congenital atrial septal defect from January 1984 to June 1993 in the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital. Anatomically, the secundum type defect was present In 58 cases and the other two were ostium primum type defect. The defect were closed directly in 45 cases and with patches in 15 cases. Preopera ive EKG findings revealed regular sinus rhythm in 81%, arrhythmia 19%, RVH 32%, RAD 30%, Postoperative findings were regular sinus rhythm in 76%, arrhythmia 24%, RVH 25%. RAD 25%. In hemodynamic data, the mean SPAP in patients over 40 years old was 41.91 $\pm$ 14.33mmHg compared to 31.46 $\pm$ 13.77 mmHg in patients under 40 years old, and the difference between the two groups was stastistically significant. And then the patients were classified into two groups (group A sinus group, and group B : arrhythmia group) according to their preoperative rhythm. The patients in group B were older, had greater value of mean SPAP and Rp/Rs. Mean Qp/qs was higher in group A. But the difference between two groups about the mean Qp/qs and Rp/Rs was not significant. Postoperative complications such as arrhythmia, pneumothorax or hemothorax occurred in 7 cases, but there was no operative mortality. The functional improvement were remarkable in half of the patients who underwent surgery.

전북의대 흉부외과학교실에는 1984년 1월부터 1993년 6월까지 치험한 20세이상의 성인 심방중격 결손 60예를 대상으로 수술전후 결과를 분석하였다. 평균연령은40.2$\pm$ 12.5세였고남녀비는 1:2.3이었다 60예의 선천성 심방중격결손증에서 1차형 심 방중격이 2예, 2차형 심방중격이 58예이었고 수술은 1차공형은 모두 심막절편으로 폐쇄하였으며, 2 차공형은 78 %에서 단순봉합을 22 %에서는 심막절편으로 결손을 폐쇄하였다. 가장 흔한 증상은 운 동시 호흡곤란이었고 술전 NYHA 기능본류는 class 110예, class II 31예, class III 19예이 었고 class IV는 없었다. 술전 심전도 소견은 동정동 환자가 81%,동성 부정맥,동성서맥과 심방세동등의 부정맥이 19%, 우측편위가 30%, 우심실비대 32%에서 있었고, 전도장애의 소견중에 서는 불완전우각차단이 22% 로 가장 많았다. 술후 변화된 심전도 소견으로는 2예에서 심 방세동이, 1예에서 동성 빈맥 이 발생되 었 으나 모두 자연소실되거나 약물투여로 맥박조절이 가능하였으며 4예에서 우심실비대의 소실을, 2예 에서 우심방확장 소실이 관찰되 었다. 혈역학적 검사성적상 평균 Qp/qs는 술전, 술후 각각 3.75$\pm$1.21와 1.17 $\pm$ 0.11, 평균 Rp/Rs는 0.11 $\pm$ 0.09와 0.09 $\pm$ 0.12, 평균 수축기 폐동맥 압은 36.18 $\pm$ 14.05rnmHg와 24 $\pm$ 3.6이었다. 혈역학적 검사 성적을40세 이상과 40세 이하의 군으로 나눠 비교한 결과 40세 이상의 군에서 유의하게 수축기폐동 맥압이 높았으며 또 동정동 군자 부정맥 군의 비교에 있어서는 부정맥 군에서 평균연령과 평균수축 기 폐동맥 압이 높았다. 수술합병증은 부정맥 3예, 각각 1예의 기흥,혈흉,간염,탈모증이 있었으며 수술 사망예는 없었다. 평균 4년 7개월의 추적관찰기간중 45%에서 술후 중상의 호전을 보였다.
