In a quantitative analysis of fluorescence study, Indocyanine green videoangiography ICG-VAG showed greater efficacy than Fluorescein videoangiography FL-VAG in visualizing relatively thick arteries, such as parent artery and superficial temporal artery (STA). However, FL-VAG has greater efficacy than ICG-VAG in visualizing perforating artery, especially in deep surgical fields with characteristic vessel walls 1).
