I looked up Marcia's question as well, since as I mentioned, I haven't had any patients with a recurrence along the lines of your inquiry.
Turns out Marcia was taken care of by my partner ( I actually never performed an IGAP on any of my patients since I didn't like the look of the donor site). So, I had no followup on her. But her mention of recurrence on the chest above the breast indicates that it was not at the IMV access site since we locate that dissection very low on the breast in our practice.
My pleasure to help, best of luck to you,
