Circumferential forearm fasciocutaneous free flap reconstruction of forequarter amputation/chest wall resection using simultaneous extra-anatomic revascularization (SEAR).

BACKGROUND

This report describes a technique in which temporary extra-anatomic revascularization of an amputated part was used to preserve a free flap while tumor resection and chest wall reconstruction were performed.

METHODS

A patient with multiple local recurrences of basosquamous carcinoma of the shoulder underwent forequarter amputation with en bloc resection of the upper chest wall. During the resection, an elbow disarticulation of the amputated limb was performed. The vascular pedicle of the amputated forearm was joined to the dorsalis pedis vessels of the foot. Following completion of tumor resection and chest wall reconstruction, the forearm was disconnected from the foot and re-anastomosed to thoracic vessels, and a circumferential fasciocutaneous free flap was then harvested and inset.

RESULTS

No ischemic flap complications occurred, and the patient recovered well. Ample time was afforded for complete tumor resection with negative margins and prosthetic reconstruction of the chest wall.

CONCLUSIONS

The technique of temporary, simultaneous extra-anatomic revascularization of an amputated part for later free flap harvest may be helpful in avoiding potentially long flap ischemia times in selected complex oncologic resections.
