Relation between Perfusion Values Directly after Surgery and Postoperative Outcome

PU	No. Flaps (n)	Postoperative Complications (n)	Comments
<20	2	2	Partial necrosis lateral (1), necrosis of mastectomy skin flap (1)
20–29	2	2	Partial necrosis, lateral (1) and medial (1)
30–39	7	0	No postoperative complications (1 flap showed stiffness of the tissue in the lower pole without need for revision)
