In Vivo Perforasome Perfusion in Hemi-DIEP Flaps Evaluated with Indocyanine-green Fluorescence Angiography and Infrared Thermography.

ABSTRACT: There are no in vivo studies that evaluate the effect of perforator dissection on the perfusion territory of a perforator (perforasome). In this study, indocyanine green fluorescence angiography (ICG-FA) and infrared thermography (IRT) were used intraoperatively to evaluate perforasome perfusion in hemi-DIEP flaps.

Methods

Patients selected for DIEP breast reconstruction were prospectively included in the study. Preoperative perforator mapping was performed with CTA and handheld Doppler ultrasound. In general anesthesia, perforasome perfusion was evaluated with ICG-FA and IRT both before surgery and after flap dissection with preserved dominant perforators.

Results

Thirty hemi-DIEP flaps were dissected in 15 patients (average BMI 26.6 kg/m²), of which 40% had been
