The Influence of Flow Velocity in the Feeding Vessel on Flap Perfusion in Deep Inferior Epigastric Artery Perforator Flap.

 The status of flap perfusion depends on the feeding vessel. The velocity of blood flow between IMA and DIEA is different, and the flap perfusion varies accordingly. Therefore, ICG angiography should be performed after anastomosis at the recipient site for an accurate assessment.
