Influence of vertical location and spacing of perforators on perfusion in deep inferior epigastric artery perforator flap breast reconstruction: quantitative analysis using indocyanine green angiography.

ABSTRACT:

Background

This study quantitatively assessed perfusion of the deep inferior epigastric artery perforator (DIEP) flap according to vertical location and vertical spacing of perforators during DIEP flap breast reconstruction.

Methods

In 67 patients who underwent unilateral DIEP flap breast reconstruction between November 2018 and August 2021, flap perfusion was intraoperatively assessed using indocyanine green angiography. Perforators located at or above the umbilicus were defined as vertical zone 1 perforators and those below the umbilicus as vertical zone 2 perforators. Perfusion assessment was conducted in two stages: at stage 1, perfusion solely by single dominant perforators was assessed. At stage 2, the perfusion increment effected by adding a single additional perforat
