Abstract

Background: This study was performed to investigate the outcomes of vascular operations that were done in patients with atheroscerosis obliterans (ASO) of lower limb. Material and Method: Forty patients underwent vascular operations from December 1996 to June 2004. The patient's records were analyzed retrospectively. Mean age was $66{\pm}8$ years (range, $47{\sim}81$ years). Gender ratio was 37:3 (male:female). Result: The operations were done on 50 lower limbs of 40 patients. The names of operations were femoropopliteal bypass in 12 patients (30%), femorofemoral bypass in 12 (30%), femorofemoral bypass and femoropopliteal bypass in five (12.5%), aorta-lower limb artery bypass in five (12.5%), axillofemoral bypass in two (5%), iliopopliteal bypass in two (5%), and endarterectomy in two (5%). All bypass surgeries were done with prosthetic conduits. Mean follow up period was $33.2{\pm}23.2$ months (range, $3.8{\sim}90.2$ months). The cumulative patency rates of 1 and 5 years were 75.5 and 58.7% respectively. In six patients, amputation of the lower limb was done. In eight patients, 12 complications occurred. After the first operation, 10 patients underwent reoperations. Conclusion: Our lower limb arterial bypass surgery revealed acceptable patency rate, but not a few patients required reoperations. An epochal treatment modality that can inhibit the progress of ASO and improve long term patency should be established.

배경: 하지의 폐쇄성 동맥경화증을 치료하기 위해 시행한 하지동맥 혈관수술에 대한 성적을 알아보고자 이 연구를 시행하였다. 대상 및 방법: 1996년 12월부터 2004년 6월까지 하지의 폐쇄성 동맥경화증으로 수술 받은 40명의 환자를 대상으로 의무기록을 토대로 후향적 분석을 하였다. 환자의 평균 나이는 $66{\pm}8$세($47{\sim}81$세)였고 성비는 37:3 (남:여)이었다. 결과: 수술은 40명에서 시행되었으며 10명의 환자에서는 양측 하지에 우회술을 시행하였다. 수술명은 대퇴-슬와동맥 우회술-12예(30%), 대퇴-대퇴동맥 우회술-12예(30%), 대퇴-대퇴동맥 우회술+대퇴-슬와동맥 우회술-5예(12.5%), 대동맥-하지동맥 우회술-5예(12.5%), 액와-대퇴동맥 우회술-2예(5%), 장골-슬와동맥 우회술-2예(5%), 내막절제술-2예(5%)였다. 모든 혈관우회술의 우회도관은 인조혈관이 사용되었다. 평균 추적기간은 $33.2{\pm}23.2$개월($3.8{\sim}90.2$개월)이었으며 우회도관의 1년, 5년간 누적 개존율은 각각 75.5, 58.7%였다. 6예에서 수술후 하지절단술이 시행되었다. 수술 후 합병증은 8명의 환자에서 12건이 발생하였다. 재수술은 10예에서 시행되었다. 결론: 본원에서 시행한 하지동맥 우회술은 비교적 양호한 개존율을 보였으나 적지 않은 환자에서 우회도관 폐쇄로 인한 재수술이 필요하였다. 하지의 폐쇄성 동맥경화증의 치료성적을 향상시키기 위해서는 동맥경화증의 진행을 억제할 수 있고 우회술의 장기 개존율을 높이는 획기적인 치료법이 연구되어야 할 것으로 생각된다.
