Abstract

Expanded polytertrafluoroethylene (expanded PTFE) graft fistulas are widely used as secondary vascu- lar access for patients receiving long-term hemodialysis treatment. We implanted 48 grafts in )5 patients during the period from August 1990 to August 1995. Forty-three grafts in 32 patients were followed for 1 to 46 months. We performed forearm straight grafts in 36 grafts and upperarm straight grafts in 7 grafts. We experienced 3 operative failures, 22 early and late complications(15 graft thrombosis). Cumulative patency for all grafts at 12 months was 63%, at 24 months 32%, at 36 months 32% Forearm graft survival at 12 months was 55%, at 24 months 30%, at )6 months 30%. Upperarm graft survival at 12 months was 8)oyo and 24 months 41%. After reviewing our experience, we think that expanded-PTFE grart as secondary vascular access still have many complications and low survival than autogenous a teriovenous fistula. And so utilization of the expanded PTFE fistula requires better techniques, close observation and maintenance to keep it functional.

Expanded polytetrafluoroethyene(expanded PTFE) 인조혈관을 이용한 동정 맥루조성술은 장기간의 혈액투석을 시행받는 환자들의 이차적인 동정 맥루조성술로서 많이 이용되고 있는 방법이다. 충남대학교병원 흉부외과에서는 1990년 8월부터 1995년 8월까지 35명의 환자에서 48례의 expanded PTFE인조혈관을 이용한 동정 맥루조성술을 시행하였고, 이중 32명의 환자 43례 에서 1개월에서 46개월 까지 추적관찰하였다. 저자들은 forearm에 36례의 수술을 시행하였고 upperarm에는 7례의 수술을 시행하였다. 수술실패가 3례, 조기 및 만기 합병증이 22례였었다(15례의 인조혈관 혈전, 기타 7례). 전체 동정맥루의 누적개존율은 12개월이 63%, 24개월 32%, 36개월 32%, 46개월이 21%였다. Fore- arm graft의 누적개존율은 12개월이 55%, 24개월이 30%, 36개월이 30%, 46개월이 20%이었으며 upperarm graft의 누적 개존율은 12개 월이 83%, 24개 월이 41%, 29개 월이 41 %였다. 위의 결과를 볼때, 이차적인 동정 맥루술로서의 expanded PTFE graft는 아직 자가정맥에 의한 동정맥루술보다 개존율이 낮고많은 합병증을 갖고 있지만, 개존율을 높이기 위해서는 더 좋은 梔行仄袖\ulcorner개발과 술후 관심 있는 관찰 및 기능을 유지하기 위한 관심이 필요하다고 생각된다.
