[Distally based sural neurocutaneous flap: clinical experience and technical adaptations. Report of 60 cases].
The distally based sural neurocutaneous flap (Masquelet et al., 1992) has proved to be a useful technique for lower limb skin defect reconstruction. We report our experience in a 60 case series for the coverage of foot, ankle, and distal third of the leg with success in 58 cases and 2 failures. For one of these, a total necrosis occurred after a technical problem when harvesting the pedicle, while the second failure was due to a severe inferior limb vascular disability. In 14 cases, a partial venous congestion with a slight epidermolysis or a marginal necrosis was observed but it resolved without sequel. Seventeen patients presented with distal vascular impairment and/or neuropathies (i.e. diabetes mellitus, arteriosclerosis, vascular lesions) of the inferior limb and our experience favour a larger pedicle trimming than in normal cases to avoid venous congestion of the skin paddle. In 18 cases, when undermining of skin between the pivot-point and the defect site to be covered was too hazardous, we used an external pedicle either temporary and severed a few weeks after or skin grafted. This is a helpful mean when local condition of the skin to be undermined for pedicle tunnelling may interfere with the final issue. This one-stage simple technique, without major vascular sacrifice and with minor consequences at the donor site, is reliable for the distal third of the inferior limb, ankle, and dorsal foot aspect reconstruction, the heel-bearing zone excepted.
