The brachioradialis is retracted laterally and the vascular bundle located in the groove between the brachioradialis and flexor carpi radialis muscles is mobilized taking care that all its branches (perforators to the muscles) are ligated.
The pedicle dissection along the intermuscular septum is continued to the level of the brachial artery. The flap is then re-perfused by releasing the tourniquet to verify the viability of the fasciocutaneous flap.
In addition it is important to also assess the vascularity of the hand at this point.
Hemostasis is obtained and the vascular pedicle is then divided when the recipient site is ready.
