  1. All analyses were conducted with the first event occurred during the follow-up period.
  2. *The fat necrosis was a kind of partial flap necrosis that could be derived from insufficient perfusion to the flap adipose tissue. Excision of fat necrosis was conducted in patients who developed palpable nodules over 2 cm in diameter on their reconstructed breasts and wanted to remove the lesions.
