Giffords' surgery scheduled for Wednesday

Posted: Updated:

Congresswoman Gabrielle Giffords is set to have surgery Wednesday to replace the piece of skull doctors removed after she was shot January 8.

The portion of her skull was removed to allow for brain swelling.

Since then she's worn a helmet while going through rehab in houston.

She will receive a plastic implant in place of the missing portion of skull.

Giffords just returned to the hehab center after watching her husband blast off into space Monday in Florida.
