title: Externally Supported, Noncoated, Knitted Dacron Graft and Gelatin-Coated Knitted Dacron Graft with Rings for Peripheral Arterial Reconstruction.
abstract: During the last 14 years, externally supported noncoated knitted Dacron grafts (EXS) and gelatin-coated knitted Dacron grafts with rings (GEL) were used in 176 patients for femoropopliteal bypass (F-P), femorofemoral bypass (F-F) and axillofemoral bypass (Ax-F). In the EXS group, 58 F-P above knee (ak), 42 below knee (bk), 25 F-F, and 19 Ax-F surgeries were performed. Twenty-three F-Pak, 5 F-Pbk, 26 F-F, and 8 Ax-F surgeries were performed in the GEL group. In the F-Pak, primary patency at 5 and 9 years was 75.5 and 53% for the EXS and that at 3 and 5 years was 75.0 and 60.0% for the GEL (n.s.). In the F-Pbk, primary patency at 5 and 10 years was 60.5 and 29.5% for the EXS, while patency at 1 year was 11.1% for the GEL (P < 0.05). In both the EXS and the GEL groups, the F-Pak surgery showed better outcomes than the F-Pbk surgery. The outcomes of the F-P grafts implanted into the legs with claudication were better than those performed for the limb salvage cases. Primary patency of the F-F and the Ax-F showed no differences and there were also no differences between the graft types. For F-Pak surgery, the EXS is the graft of choice. The GEL is not suitable for F-Pbk surgery. For F-F and Ax-F reconstruction, both the EXS and the GEL are acceptable.
