| Abstract |
Purpose
We have successfully reconstructed the digital arteries, and so salvaged the finger as well as reconstructing the soft tissue and skin by using a flow-through arterialized venous free flap. Because this is more advanced than the simultaneous vein graft and skin graft or other flaps, we report here. Materials and Methods: Five patients underwent flow-through arterialized venous free flaps as a result of trauma. Of five patients, three had an amputation of finger and two needed revascularization. All patients had the defects of soft tissue in the injured finger. These flaps were harvested from the volar wrist (3 cases) and thenar (2 cases). Results: All five flow-through arterialized venous free flaps were completely survived. The sizes of the flap ranged from 1 cm2 to 5.95 cm2 (mean size; 2.29 cm2). The mean follow-up period was 9.6 months. We successfully performed simultaneous digital revascularization and soft tissue coverage in finger injuries by the flowthrough arterialized venous free flap. Conclusion: The flow-through arterialized venous free flap is very useful in the reconstruction of ischemic digits requiring simultaneous flap coverage, especially if the arterial reconstruction necessitates a vein graft. |
