Utility of Indocyanine Green Angiography in Arterial Selection during Free Flap Harvest in Patients with Severe Peripheral Vascular Disease.
Indocyanine green angiography (SPY) was used to guide arterial selection for an anterolateral thigh free flap in the setting of severe peripheral vascular disease. SPY technology serves as a novel and sensitive intraoperative tool to predict decreased tissue perfusion from vessel sacrifice for flap harvest. Change in SPY time parameters measuring superficial blood flow distal to the donor site while temporarily intraoperatively clamping different possible arterial pedicles can optimize free flap design to avoid iatrogenic critical limb ischemia.
