Musculocutaneous pedicled venous flaps on the dorsum of rats survived at a statistically significantly higher rate than musculocutaneous composite grafts (p<0.01). With a Silastic® sheet (Dow Corning) beneath, both composite grafts and pedicled venous flaps necrosed. When a Silastic® sheet with holes in it to allow some revascularisation from the bed was placed beneath, the survival rate was significantly better than with a complete Silastic® sheet (p<0.01). These results demonstrate that pedicled venous flap survival depends both on the draining vein, and revascularisation from the underlying bed.
