Design outcomes

Primary

Measure	Time frame
Partial necrosis and partial fat necrosis of the flap in the early postoperative period (3-6 months postoperative) and mid-term (approximately 1 year postoperative)	—

Secondary

Measure	Time frame
Correlation between the number and location of perforating branches included in the flap and early- and mid-term postoperative flap complications in the surgical findings documented in the medical record. Relationship between the number and location of perforating branches included in the flap and the extent of intraoperative ICG fluorescence contrast of the flap in the surgical findings documented in the medical record. Evaluation of flap complications and reconstructed breast morphology in the early and mid postoperative period. Long-term evaluation of the above items will also be performed in cases in which long-term postoperative follow-up (approximately 3 years postoperatively) is possible.	—
