Modified free paraumbilical perforator flap: the next logical step in breast reconstruction.

The free paraumbilical perforator flap that was developed with only the perforator penetrating the rectus abdominis muscle seems nearly ideal from the donor-site perspective, because it reduces morbidity virtually to that of an abdominoplasty. However, it requires "supermicrosurgery" skills for suturing of vessels with diameters of 0.7 mm or less, making the procedure technically demanding and risky. Another significant disadvantage of that technique is that the flap has very short vascular pedicles. To overcome the disadvantages of the free paraumbilical perforator flap, a minor modification in flap harvesting that improves the vessel size and length is described. Results for a total of 15 patients who underwent breast reconstruction with modified free paraumbilical perforator flaps are presented, and the advantages and disadvantages of this flap are discussed.
