Groups | Surgery | Survival time 2 weeks (N) | Survival time 12 weeks (N) | Survival time 16 weeks (N) |
---|---|---|---|---|
I | Autograft | 5 | 6 | 6 |
II | Optimized processed allograft (OPA) | 5 | 6 | 6 |
III | OPA + SIEF flap | 5 | 6 | 6 |
Ten-mm sciatic nerve gaps were reconstructed with an autograft (group I, gold standard), an optimized processed allograft (group II, OPA), or an OPA wrapped in a pedicled superficial inferior epigastric fascial (SIEF) flap (group III). Rats were sacrificed at two, 12 and 16 weeks to measure vascularization.
