A safe, reliable method for skin-graft coverage of the radial forearm donor site.

Delayed donor-site healing remains one of the most significant disadvantages of the radial forearm free flap. In an effort to decrease morbidity at the donor site, the authors adopted a closure technique that utilized the flexor digitorum sublimis (FDS) and flexor pollicis longus (FPL) muscle bellies to cover the flexor carpi radialis (FCR) tendon prior to placement of a split-thickness skin graft. While this approach eliminated tendon exposure, two patients with postoperative median-nerve compression forced a modification of this technique. The authors now detach the radial attachment of the FDS muscle and mobilize the median nerve away from the underside of the muscle, to prevent kinking of the nerve when the FDS and FPL muscle bellies are sewn together. With these modifications, the technique retains its efficacy, but with an improved margin of safety for the median nerve.

The management of unsalvageable free flaps.

The loss of vascular flow in the early postoperative period will generally lead to free flap failure. When attempts at flap salvage are unsuccessful, conservative management with delayed flap debridement may be indicated. Seven unsalvageable free flaps were managed with observation and flap debridement 4 to 14 days following loss of vascular signals. At the time of debridement, six of the seven wounds had viable granulation tissue and were successfully closed with skin grafts. The seventh patient had loss of vascular flow to the free flap within 12 hr of surgery and, at the time of delayed debridement, had no evidence of granulation ingrowth. Local revascularization of flaps is known to occur and offers an explanation for these findings. Delayed debridement of unsalvageable free flaps is indicated for noncritical wounds, and may obviate the need for a second free-tissue transfer to obtain wound closure.

The role of vascular pedicle thrombectomy in the management of compromised free tissue transfers.

Microvascular free tissue transfer has become a very reliable reconstructive technique. Occasionally, flap compromise will occur and will require urgent flap reexploration. In the setting of complete thrombosis of pedicle vessels, thrombectomy using Fogarty #2 and #3 catheters can be effective in restoring vascular patency. Seven flaps with arterial, venous, or both vessel thrombosis were managed with thrombectomy at the time of reexploration and anastomotic revision. Six of the flaps were completely salvaged and the seventh was partially salvaged. Promptness in reexploration increased the likelihood of complete flap salvage. The use of postthrombectomy heparinization was associated with a 50% complication rat in this series. Thrombectomy of free flap vessels can be safely performed and is associated with a low incidence of rethrombosis.
