Microvascular modifications to optimize the transverse upper gracilis flap for breast reconstruction.

The free transverse upper gracilis flap is well described for breast reconstruction and is the authors' second choice. Medial thigh soft tissue creates a durable, pliable, aesthetic breast; however, it has been criticized for modest volume and short pedicle. This demands frequent use of bilateral flaps for unilateral reconstructions, sacrifice of thoracodorsal vessels, and/or use of vein grafts. The authors have overcome these issues by modifying their microvascular techniques.
