Abstract

There remains controversy regarding the appropriate surgical treatment for coarctation of the aorta because of relatively high rate of recoartation and high mortality in the cases associated with complex anomalies. We evaluated 31 consecutive patients who underwent surgical repair of coarctation of the aorta from May 1992 through June 1996. Nineteen patients(61.3%) were neonates and 26(83.9%) were under three months. Nine patients did not have major associated anom lies(Group I), 15 patients had ventricular septal defect(Group II), and 7 patients had major complex anomalies(Group III). 35.5% of the patients had arch hypoplasia. Surgical procedures performed were as follows: extended end-to-end anastomosis in 17 patients, combined resection-flap procedure in 7 patients, and subclavian flap aortoplasty in 7 patients. Residual coarctation occurred in 7(25%) of 28 patients; 2 after subclavian (lap aortoplasty(2/6, 33.3%), none after combillrd resection-flap procedure(0/7, 0%), and 5 after extended end-to-end anastomosis(5/15, 33.3%). Higher incidence of residual coarctation was noticed in the group with arch hypoplasia. The incidence of postoperative coarctation at a mean follow-up of 20.5 months in survivals was 12.0%(3/25); 2 cases after subclavian flap aortoplasty(2/6, 33.3%), none after combined resection-flap procedure(017, 0%), and one after endtoend anastomosis(1/12, 8.3%). The mortality rate related to coarctation repair was 9.7%(3 patients all in Group III). This study revealed that isolated coarctation of aorta and coarctation with ventricular septal di3fect(groups I & ll) can be repaired with low mortality, but repair of coarctation with complex anomaly had a high operative mortality Also the patients with arch hypoplasia had higher incidence of post-operative residual coarctation.

1992년 5월부터 1996년 6월까지 외과적으로 치료한 31례의 대동맥축착증의 중단기 성적을 검토하였다. 모두 31명의 환아중 19명(61.3%)이 신생아였으며 26명(83.9%)이 생후 3개월이내의 유아였다. 동반기형에 따라 세군으로 나누었는데 중요한 기형이 동반되지 않은 군(group I)이 9명, 심실중격결손을 동반한 군(group II)이 15명, 복잡심기형이 동반된 군(group III)이 7명이었다. 35.5%(11명)의 환아에서 대동맥궁의 형성부전이 동반 되었다. 수술방법으로는 17명의 환아에서 확장단단문합술, 7명에서 단단문합술과 쇄골하동맥편성형술을 함 께 시행(combined resection and flap pmcedure)하였고, 나머지 7례에서는 쇄골하동맥편성형술을 시행하였다. 술후 잔존협착은 술후 쟌존협착을 측정하였던 28례중 7례(25%)에서 발생하였고 쇄골하동맥편성형술후 6례중 2례(33.3%), 단단문합술과 쇄골하동맥편성형술을 함께 시행한후 7례중 없었으며, 확장단단문합술을 시행한 15례의 환아중 5례(33.3%)에서 발생하였다. 생존환아에서 평균 20.5개월의 추적기간후 술후 대동맥축착은 모 두 3례로 12%(3/25)였다. 이를 수술방법에 따른 빈도를 보면 쇄골하동맥편성형술후 6 恪\ulcorner2례(33.3%), 단단문 합술과 쇄골하동맥편성형술을 함께 시행한 7례중 없었으며, 확장단단문합술을 시행한 12례의 환아중 1례 (8.3%)에서 발생하였다. 대동맥축착증의 수술과 관련된 사망은 3례(9.7%)로 모두 복잡심기형을 동반한 군에서 발생하였다. 결론적으로 복잡기형을 동반하지 않은 경우(1, ll군)는 대동맥축착증의 수술과 관련된 수술사 망은 없었으며 복잡기형을 동반한 대동맥축착증의 수술은 높은 사망률을 보였다. 또한 대동맥궁형성부전증 이 있었던 경우에서 없었던 경우보다 더 높은 술후 잔존정착의 빈도를 보여 이의 적절한 치료가 요구되었다.
