Outcome Measures

Primary Outcomes (1)

  • Deep Inferior Epigastric Perforator Flap Zone IV Tissue Perfusion

    Tissue Perfusion to Zone IV will be assessed intra-operatively using Laser Doppler Imaging and angiography whilst various components of the Contralateral Superficial Inferior Epigastic Artery / Vein are clamped/unclamped.
