Abstract

Introduction

The concept of extended thoracodorsal artery perforator (TDAP) flap was described in 2015 for breast reconstruction. Our anatomical study aims to identify the territories vascularised by the thoracodorsal artery perforator via the deep muscular fascial network. The second goal was to define the volume of the extended TDAP flap.

Materials and method

Ten extended TDAP flaps were dissected on 5 fresh human cadavers. Around the classical skin paddle of a TDAP flap, the dissections were performed in a subfascial level, including the muscular fascia and the adipose tissue compartments to increase the volume of the flap. After injection of methylene blue in the thoracodorsal artery, we measured the length and width, the surface and the volume of the coloured flap.

Results

The mean sizes of the extended TDAP flap were 24.9 cm × 20.1 cm. The mean surface of the total vascularization zone was 441 cm². The mean volume of the vascularized flap was 193 ml.

Conclusion

The thoracodorsal artery perforator via the deep muscular fascial network allows us to harvest a flap of 25 cm × 20 cm with a mean surface of 441 cm² and a mean volume of 193 ml. The extended TDAP flap is a credible option in breast reconstruction.
