초록

배경: 대동맥궁 치환 수술 시 뇌 보호법은 필수불가결하며, 다양한 방법이 시도되고 있다. 이중 순행성 뇌관류법의 이용은 완전 순환 정지시간을 최소화하고 뇌관류를 가능하게 하여 중추신경계 합병증을 줄일 수 있는 방법 중의 하나이다. 본 연구의 목적은 우액와동맥을 통한 순행성 뇌관류를 이용하여 대동맥궁 치환술을 시행한 환자들의 임상 결과를 조사하는 데 있다. 대상 및 방법: 2004년 7월부터 2006년 7월까지 대동맥궁 치환 시 대동맥궁 분지의 전부 혹은 일부를 치환 후 우액와동맥을 통한 순행성 뇌관류를 시행하면서 대동맥궁 치환을 한 11명의 환자를 대상으로 하였다 남자 환자는 9명, 여자 환자는 2명이었다. 수술 당시의 진단은 A형 대동맥 박리(5/11, 45.5%), A형 벽내혈종(1/11, 9%), 대동맥류(5/11, 45.5%)였고, 평균 나이는 $60.3{\pm}12.8$세였다. 우액와동맥으로 삽관하여 심폐기 가동 후 초저체온 상태(평균 최저 비인두 체온 $11.7{\pm}1.0^{\circ}C$)에서 완전순환정지를 시행하였고, 이 기간 중 일부에서 역행성 뇌관류법을 시행하였다. 결과: 완전 순환 정지 시간은 $31.1{\pm}16.9$분이었으며 역행성 뇌관류 시간은 $21{\pm}17.8$분이었다. 뇌관류를 위한 각각의 도관과 대동맥궁 분지를 연결하는 데 걸린 평균시간은 $24.1{\pm}9.3$분이었다. 술 후 사망 환자는(0/11, 0%) 없었고, 영구적 신경학적 합병증 또한 없었다. 결론: 더 많은 수의 환자와 장기적인 성적에 대한 연구가 필요하지만 우액와동맥을 통한 순행성 뇌관류를 이용한 대동맥궁 치환술은 대동맥궁 조작을 최소화하고 색전 및 전반적인 허혈에 의한 뇌합병증을 줄일 수 있는 방법으로 생각된다.

Background: Cerebral protection is one of the most important procedures during aortic arch surgery. We can minimize neurological complications through short period of total circulatory arrest and resuming of brain perfusion. We evaluated 11 patients who underwent arch replacement using antegrade brain perfusion via right axillary artery. Material and Method: Between July 2004 and July 2006, 11 patients (male 9, female 2) underwent aortic arch replacement with antegrade brain perfusion via right axillary artery. Preoperative diagnosis was listed; 5 type A aortic dissections (5/11, 45.5%), 5 aortic aneurysms (5/11, 45,5%) and 1 type A IMH (intramural hematoma, 1/11, 9%). The mean age at the time of operation was $60.3{\pm}12.8$ years. For antegrade brain perfusion, we performed right axillary artery cannulation in all patients. Retrograde brain perfusion was used briefly during total circulatory arrest. Result: The mean total circulatory arrest time was $31.1{\pm}16.9$ minutes and the mean retrograde brain perfusion time was $21{\pm}17.8$ minutes. Mean antegrade brain perfusion time was $77.9{\pm}17.5\;(43{\sim}101)$ minutes. We had neither operative mortality nor permanent neurological complications. Conclusion: By means of antegrade brain perfusion via right axillary artery, that could lead to decrease circulatory arrest time and minimize damages to severely atheromatous arch vessels, we can expect to reduce neurological complications after aortic arch replacement. Further investigation with iarge patient populations will be required.
