• The perfusion territory of the pedicled internal mammary artery perforator flap has been described, but the number of perforators to be included in the flap's pedicle is controversial. We studied the vascular territory of the dominant perforator and the contribution of additional nondominant perforators to it. Therefore, the dominant perforators in 9 fresh cadavers and the nondominant perforators in 4 of these, were injected with water-based ink. The dominant perforator vascularized a territory extending from the superior border of the clavicle to the xiphoid, and from midsternal to the anterior axial fold, with a mean craniocaudal length of 19.4 cm (range, 17.0-24.0) and a mean mediolateral width of 18.6 cm (range, 16.0-22.5). Additional injection of nondominant perforators did not lead to any substantial enlargement of this territory. One single dominant perforator vascularizes a large part of the hemithorax, allowing for various flap designs. Nondominant perforators do not have to be included in the vascular pedicle of the internal mammary artery perforator flap, which leads to less donor-site morbidity.
