Fixing PAH and breasts fat transfer

I think the two issues are unrelated as long as you are not harvesting fat anywhere you had CoolSculpting. Freezing fat results in damage and inflammation to the treated area and subsequent scar tissue where the treatment was performed, making fat harvest from these areas unreliable and unpredictable in terms of viability.

Dear Trustworthy948671,
it is hard to tell for sure without an examination. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

You have healed well enough to go with liposuction and a fat transfer. I do not recommend using any fat involved with the PAH.

It sounds like you’re making things a bit too complicated.
In the end provider selection is by far the most important variable, and this will most likely supersede any issue with PAH or not.
Understanding your candidacy, what the procedure can and cannot accomplish and finding the right surgeon are the things to focus on.
Best,
