Abstract

Background: Aortic diseases tend to involve the entire aorta. Hence, there is the constant possibility of the need for a secondary operation at the remnant aorta. This study analyzed our cases of secondary aortic surgery in order to determine its characteristics and problems. Material and Method: Between April 2003 and June 2007, 12 patients (6 male and 6 female) underwent thoracoabdominal aortic replacement as a secondary aortic operation. Their clinical courses were analyzed. Four of the patients underwent lower thoracobadominal aortic replacement under the normothermic femorofemoral bypass, and the others underwent an entire thoracobdominal aortic replacement under deep hypothermic circulatory arrest. Result: There was no death or paraplegia. As local complications, there were 3 cases of wound infection and 2 cases of an immediate reoperation caused by bleeding and one case of delayed wound. revision for a contaminated perigraft hematoma. As a systemic complication, there was one case of renal insufficiency, which required hemodialysis and one case of respiratory insufficiency that needed prolonged ventilator care. The mean admission period was $30{\pm}21$ days. All the patients were followed up for $626{\pm}542$ days without reoperation or other problems. Conclusion: Using properly selected patients and a careful approach, thoracoabdominal aortic replacement can be performed safely as a secondary aortic surgery.

배경: 대동맥질환은 전 부위의 대동맥이 병변을 일으키는 특성이 있으므로 수술을 받은 후 다른 부위에 이차 수술의 가능성이 언제나 남게 된다. 이차 대동맥 수술의 특징과 문제점을 알아보고자 본 연구를 시행하였다. 대상 및 방법: 2003년 4월에서부터 2007년 6월까지 본원에서 대동맥 이차 수술로 흉복부 대동맥 치환술을 받은 12명의 환자(남자 6명 여자 6명)를 대상으로 임상 경과를 조사하였다. 수술은 대퇴동정맥간 우회로술로 시행한 하부 흉복부대동맥치환술 4예와 극저체온하 순환정지하에서 시행한 광범위 흉복부대동맥치환술을 8예 시행하였다. 결과: 수술 사망이나 하지 마비는 없었고 국소 합병증으로 창상감염 3예, 출혈로 인한 재수술 2예, 오염된 혈종으로 인한 재수술 1예 등이 발생하였다. 그 외 혈액투석 1예, 호흡부전 1예 등이 있었으며 평균 입원기간은 $30{\pm}21$일이었다. 평균외래 추적 $626{\pm}542$일 동안 재수술 증례 없이 모두 경과 관찰 중이다. 결론: 응급 상황에 도달하기 전의 적절한 시기에 극저체온 순환정지법을 사용한다면 흉복부대동맥치환술은 이차 대동맥 수술의 좋은 치료법이 될 수 있을 것이다.
