Abstract

From Dec. 1992 to Dec. 1995, 20 patients with atherosclerotic occlusive disease in the lower extremities underwent arter al bypass surgery. The age of the patients ranged between 46 and 77 years(mean .60.8 years) and the most prevalent incidence was in the 7th decades. The mean follow up period was 18.8 months ranging from 4 to 36 months. Associated diseases were diabetus mellitus(25%), hypertension (35%), cerebrovascular accident(25%), and acute myocardial infarction(5%). Disabling intermittent claudifcation(35%), resting pain(20%) or ischemic gangrene(or ulceration)(45%) were operative indications. Aorto-bifemoral bypass in 4 cases, aorto-single femoral bypass in 2 cases, Aorto-bifemoral bypass and femoropopliteal bypass in 3 cases, aorto-single femoral bypass and femoropopliteal bypass in 1 case, femoropopliteal bypass in 4 cases, femorotibial bypass in 1 case, popliteotibial bypass 4 cases and femorofemoral bypass in 1 case were the surgical approches. Early thrombosis(2 cases) and wound infection(2 case) were main complication. Postoperative complication rate was 20% . Postoperative patency rates re 92.6% at 6 months, 84.2% at 1 year, 75.4% at 2 years and 69.4% at 3 years.

복부대동맥과 그 이하 주요분지들의 동맥폐쇄에 의한 하지 만성허혈은 동맥경화증이 주원인이며 이 질환의 임상적 중요성은 혈관이 진행적으로 폐쇄됨에 따라 혈류장애가 발생하여 간헐적 파행, 휴식시 동통이 일어나며 더 진행되면 조직의 괴사가 발생,결국괴사된 조직의 절단을 초래하게된다. 본한국보 훈병원 흉부외과에서는 1992년 12월부터 1995년 12월까지 폐쇄성 하지동맥 경화증으로 입원한 20명의 환자를 대상으로 동맥간 우회술을 시 행하였다. 임상증상은 괴사및 괴저 9례(45B4), 파행 7례(35%), 안정 시 동통 4례(20%)순이었다. 사용한 혈관은 복부대동맥및 총대퇴동맥의 경우 Y-형및 I-형 인조혈관을 사 용하였고 대퇴동맥이하의 혈관에서는 주로 자가 대복재정 맥을 사용하였다. 술후 합병증은 4례로 20% 를 보였고 이식된 혈관내 혈전증 2례, 창상감염 2례 였다. 술후 혈관개존율은 복부대동맥과 양측 대퇴동 맥간 우회술의 경우 100%였고 대퇴동맥 이하에서는 6개월이 92.6%, 1년 84.2%, 2년 75.4%, 3년 69.4% 였다.
