Abstract

Background: The optimal therapeutic strategies for patients with coarctation of the aorta(CoA) and ventricular septal defect(VSD) remain controversial. This study was undertaken to determine the outcome and the need for reintervention following single-stage repair of coarctation with VSD in infants younger than 6 months. Material and Method: Thirty three consecutive patients who underwent single-stage repair of CoA with VSD, from January 1995 to December 2000, at Sejong General Hospital were reviewed retrospectively. Mean age and body weight at repair were 54$\pm$37 days(12 days-171 days) and 3.9$\pm$1.1 kg(1.5~6 kg), respectively. The surgical repair of CoA was performed under deep hypothermic circulatory arrest(CA) in the early period of the study and under regional cerebral perfusion through a direct innominate arterial cannulation without CA in the later period. The technique used in the repair of the CoA was resection and extended end-to-end anastomosis(EEEA; n=16) and extended side-to-side anastomosis(ESSA; n=2) in the early period, and resection and extended end-to-side anastomosis(EESA; n= 15) in the later period. The simultaneous closure of VSD was done with a Dacron patch(n= 16) and autologous pericardium(n=17). Aortic arch hypoplasia was present in 29 patients(88%) and its types were distal(n=18), complete(n=5), and complex(n=6)

배경: 대동맥 축착증과 심실중격결손이 동반된 환아의 적절한 치료 방침에 대해서는 이견이 많다. 본 연구는 생후 6개월 이하의 환아에서 대동맥 축착증과 심실중격결손의 일타 완전교정 결과 및 수술방법에 따른 대동맥 축착증의 재발에 대해 알아보고자 하였다. 대상 및 방법: 1995년 1월부터 2000년 12월가지 본원에서 대동맥 축착증과 심실중격결손으로 일차 완전교정을 시행받은 생후 6개월 이하의 환아 33명을 대상으로 후향적으로 조사하였다. 환아의 평균 연령과 체중은 각각 54$\pm$37일(12일~171일)과 3.9$\pm$1.1kg(1.5~6kg)이었다. 대동맥 축착 고정은 연구 초기에는 저체온하 완전순환정지하에서 시행하였으며 최근에는 순환정지없이 무명동맥을 통한 국소 뇌관류 상태에서 시행하였다. 축착증 교정 방법은 초기에는 Extended cad-to-end anastomosis(EEEA;n=16)와 Extended side-to-side anastomosis(ESSA;n=2)를, 최근에는 Extended end-to-sidc anasto mosis(EESA;n=15)를 이용하였다 심실중격결손은 초기 16명에서는 Dacron을, 최근 17명에서는 자가 심낭편을 이용하여 폐쇄하였다. 대동맥궁 발육부전은 29명(88%)에서 있었으며 원위부 발육부전 18명, 완전형 5명, 그리고 복잡형은 6명이었다.
