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.
