초록

배경: 본 연구는 대동맥근부를 침범한 상행대동맥류 환자에서 composite valve graft를 이용한 대동맥근부 치 환술 결과를 알아보고자 하였다. 대상 및 방법: 1995년 4월부터 2001년 6월가지 composite valve graft를 이용한 대동맥근부 치환술 환자 56명을 대상으로 후향적으로 조사하였다. 대동맥판막 폐쇄부전은 50명(89%), Mafan증후군이 18명(32%), 그리고 이엽성 대동맥판막이 7명(12.5%)에서 동반되었다. 진단은 대동맥판륜 확장증 30명(53.6%), 대동맥 박리증 13명(23.2%), 대동맥근부를 침범한 상행대동맥류 11명(17.6%), 그리고 대동맥염이 2명(3.6%)이였다. 대동맥 파열로 인한 심낭 압전 및 심인성 쇽은 2명에서 있었으며 과거에 심장이나 상행대동맥 수술을 받은 환자는 9명(16%)이었다. 근부치환술시 사용된 수술방법button술식 51명(91%), 변형 Cabrol 술식 4명, classic Bentall 술식을 1명에서 시행하였다. 동반수술은 대동맥궁 치환술 24명(43%), 관상동맥우회술 8명(14.3%), 승모판 성형술 2명 및 재치환술 1명, 기타 7명이었다. 평균 순환정지, 체외순환및 대동맥차단 시간은 각각 21$\pm$14분(6-60분), 186$\pm$68분과 132$\pm$42분이었다. 결과: 조기 사망은 1명(1.8%)에서 있었고 술후 합병증으로는 심기능 부전이 16명(28.6%), 출혈로 인한 재수술 7명(12.5%), 심낭삼출 2명, 그리고 기타가 6명이었다. 술후 생존자 55명중 53명(96.4%)에서 평균 23.2$\pm$18.7개월(1-75개월)을 추적하였다. 만기 사망은 외상성 뇌출혈로 사망한 1명을 포함해 2명(3.8%)이었으며 대동맥근부 치환술과 관련한 만기 사망률은 1.9%였다. 한편 술후 1년과 6년 survival rate는 각각 98.1$\pm$1.9%와 93.275.1%였다. 대동맥근부 치환술과 관련한 합병증으로 재수술이 2명에서 시행되었으며(3.8%), 1년과 6년 후 재수술로부터의 freedom rate는 각각 97.872.0%와 65.3$\pm$26.7%였다. 잔여 대동맥에 대한 수술은 술전에 동반된 흉복부대동맥류의 확장으로 2명에서 흥복부대동맥류 치환술을 시행하였다.

This study was undertaken to analyze the outcome of composite valve graftreplacement(CVGR) for the treatment of aneurysms of the ascending aorta involving the aortic root. Material and Method: Between April 1995 and June 2001, 56 patients had replacement of the ascending aorta and aortic root with a composite graft valve and were reviewed retrospectively. Aortic regurgitation was present in 50 patients(89%), Marfan's syndrome in 18 patients(32%), and bicuspid aortic valve in 7(12.5%). The indications for operation were annuloaortic ectasia(AAE) in 30 patients(53.6%), aortic dissection in 13(23.2%), aneurysms of the ascending aorta involving aortic root in 11(19.6%), and aortitis in 2(3.6%). Cardiogenic shock due to the aortic rupture was present in 2 patients. Nine patients(16%) had previous operations on the ascending aorta or open heart surgery. The operative techniques used for CVGR were the aortic button technique in 51 patients(91%), the modified Cabrol technique in 4, and the classic Bentall technique in 1. The concomitant procedures were aortic arch replacement in 24 patients(43%), coronary artery bypass graft in 8(14.3%), mitral valve repair in 2, redo mitral valve replacement in 1, and the others in 7 The mean time of circulatory arrest, total bypass, and aortic crossclamp were 21$\pm$14 minutes, 186$\pm$68 minutes, and 132$\pm$42 minutes, respectively. Result: Early mortality was 1.8%(1/56). The postoperative complications were left ventricular dysfunction in 16 patients(28.6%), reoperation for bleeding in 7(12.5%), pericardial effusion in 2, and the others in 7. Fifty-three patients out of 55 hospital survivors were followed up for a mean of 23.2 $\pm$ 18.7 months(1-75 months). There were two late deaths(3.8%) including one death due to the traumatic cerebral hemorrhage, and CVGR-related late mortality was 1.9%. The 1- and 6-year actuarial survival was 98.1$\pm$1.9% and 93.2$\pm$5.1%, respectively. Two patients required reoperation for complication of CYGR(3.8%) and two other patients required subsequent operations for dissection of the remaining thoracoabdominal aorta. The 1- and 6-year actuarial freedom from reoperation was 97.8$\pm$2.0% and 65.3$\pm$26.7%, respectively.
