Preferred use of the ipsilateral pedicled TRAM flap for immediate breast reconstruction: an illustrated approach

Recent experience with the ipsilateral TRAM flap has shown that it has the advantage of a longer functional pedicle length, which allows tension-free inset of well-vascularized tissue into the breast pocket. This leads to better positioning and shaping of the reconstructed breast with minimal disruption of the inframammary fold. The purpose of this article was to provide an illustrated approach to the ipsilateral TRAM flap and to clarify the technique when applied in the context of immediate breast reconstruction following cancer extirpation.

A prospective evaluation of 89 patients who underwent immediate breast reconstruction following skin-sparing mastectomy for breast cancer was performed. All patients underwent ipsilateral TRAM reconstruction. The innate insetting advantage of the ipsilateral TRAM flap is illustrated in the article. The key steps of the technique were as follows: (1) The ipsilateral corner of the flap was used as the axillary tail, leaving the more bulky part to form the main body of the breast; (2) To avoid undesirable twists, a right TRAM was rotated clockwise so that its apex points superiorly; (3) This flap was subsequently tunneled into the breast pocket while preserving the inframammary fold. The opposite maneuvers were done for the left side; (4) If the flap was congested, venous augmentation was performed where the tributary of the axillary vein or the thoracodorsal vein was anastomosed with the inferior epigastric vein from the flap with an interposed vein graft (17% of cases).

All flaps survived and flap-related complications included partial necrosis of tissue across the midline (2.2%), palpable fat necrosis (22%), and hematoma requiring drainage (2.2%). All flaps were raised concurrent with the resection, and the combined operative time ranged from 3.5 to 6 h, with a mean hospital stay of 7 days.

The ipsilateral TRAM flap was a reliable flap with low complication rates and short surgery time. It was our preferred choice for pedicled breast reconstruction in all cases, except for the ptotic breast or if abdominal scarring excludes its use.
