Reconstructive Surgery with Expanders - Infected

Based on the pictures and information in your question, I feel that the breast implants should be removed, cultures should be obtained from the wounds, and the infection should fully controlled first.

Once the infection is fully resolved and tissues have softened, then reconstruction with a flap breast reconstruction technique should be considered. 

The flap breast reconstruction techniques do not use breast implants, so this avoid the problems of infected breast implants, displaced or exposed breast implants.

The flap reconstruction options create a breast that is entirely your own tissues resulting in a warn, soft, natural breast.   You need a consultation and detailed discussion with a reconstructive plastic surgeon to determine if you  are candidate for flap breast reconstruction such as a TRAM flap, or DIEP flap.

Sorry, but it sounds like you have an infected expander.  More than likely this should come out and reconstruction should be delayed for a few months to allow things to settle down.

I am so sorry that you are experience what appears to be a cellulitis/skin infection.   Its good that there is an infectious disease (infection and antibiotic) specialist on your team.   It also sounds as if your team and you have decided to try to treat this cellultiis with IV antibiotic therapy with a PICC line.   Now after an attempted treatment, if you still remain very red or are experiencing fevers, then your surgeon may need to remove your implant.  Once the foreign body tissue expander implant has been removed, most implant related infections quickly resolve.  I generally recommend waiting 2-3 months before you consider other reconstructive options.  Should your implant need to be removed, don't worry, your plastic surgeon will have other options for you to come back a restore your breast another day. Best of luck.
