PVP breast implants after two years: initial results of a prospective study

A prospective study of a new mammary prosthesis with PVP-based gel as filling material was carried out. Scheduled follow-ups were planned at 3, 6, 12, and 24 months post-implantation to assess all complications, Baker scores, and the patient's, and the physician's global assessment of each implant. PVP-filled implants were used in 95 breasts for augmentation (60%) or reconstruction (40%). Sixty-nine percent of all patients underwent a primary procedure, 19% had a history of severe capsular fibrosis. During follow-up, a hematoma was observed in 2% and a seroma in 5%. Leakage occurred in 3% (one iatrogenic and two cases of unknown reason), a Baker 3 in 6% (12 months). No volume increase of the implants occurred. The probability that a patient would be complication-free at 24 months was 0.86. Physician's and patient's satisfaction rating after 12 months remained high without any time effect (physician very good/good 63%, patient 75%). According to our current experiences, the PVP-filled implants are a remarkable alternative with an improved viscosity and enhanced x-ray transmission, compared to saline filled implants.
