Use of Thoracodorsal Artery Perforator (Tdap) Flap to Cover a Laparoscopically Harvested Omental Flap After Modified Radical Mastectomy; a Case Report.

Omental flap was introduced for breast reconstruction after mastectomy either alone or as an adjunct to prosthetic reconstruction. Laparoscopically harvested omental flap was used successfully for this issue. Most of reports had described its use after partial mastectomy, skin or nipple areola sparing mastectomies. In this case, we used the thoracodorsal artery perforator (Tdap) flap as a cover for the omental flap in a patient who underwent modified radical mastectomy. Modified radical mastectomy was done in the usual fashion. The descending branch of the thoracodorsal vessel was traced till its main perforator in an antegrade fashion. Then, the supplied skin island flap was created and rotated to cover the laparoscopically harvested omental flap that was delivered after its mobilization through a small epigastric wound from underneath the inner aspect of the lower mastectomy flap. The overall operative time was around 150 min. No blood transfusion was required. Pain score was around 6-7 in the early postoperative hours. No major complications were encountered, and the patient was discharged at the third postoperative day. The overall esthetic score was expressed as "good." To our knowledge, this is the first time to report usage of laparoscopically harvested omental flap after modified radical mastectomy with skin coverage by the thoracodorsal artery perforator (Tdap) flap. One criticism that may arise is the dual flap reconstruction; however, this method still as an alternative to the myocutaneous flaps with a reasonable operative time and minimal donor site and overall morbidities with good esthetic outcome. Modified radical mastectomy can be safely and efficiently reconstructed using a laparoscopically harvested omental flap with a cutaneous coverage using the thoracodorsal artery perforator (Tdap) flap.
