Results after implantation of gelatine-impregnated bifurcated grafts.
In two randomized prospective trials grafts impregnated with gelatine were compared to those not impregnated. In the first trial a double-velours graft (n = 50) was compared with a graft without velours trimming (n = 50) implanted in the aorto-iliac bifurcation. One half of the grafts in both groups were gelatine-impregnated. In the second trial 24 grafts without velours trimming (Cooley II, Meadox), 24 grafts manufactured by a new warp-knitting procedure without velours trimming (Protegraft 2000, B. Braun AG) and 24 identical grafts of B. Braun AG but with gelatine impregnation were evaluated. Gelatine-impregnated or not the grafts without velours showed no satisfying results. An elevated intraoperative bleeding incidence and a low two-years-patency rate of 64% were noted. On the other hand all double-velours grafts, gelatine-impregnated or not, showed a 100% patency rate two years after implantation. In the second trial a slight reduction in intraoperative blood loss was noted when using the gelatine-impregnated grafts.
