Indocyanine green intravenous administration can more accurately identify the intersegmental plane than the inflation-deflation method in lung segmentectomy

Relationships between the surgical margin and the distance of STAS from the primary tumor among the lesions with STAS.
(A) I-D group (n = 11). The median surgical margin was 16 mm (6–77), and the median distance of the STAS from the primary tumor was 3 mm (1–7), showing a significant difference (P < 0.001). (B) ICG-iv group (n = 8). The median surgical margin was 19 mm (11–30), and the median distance of the STAS from the primary tumor was 1 mm (1–8), showing a significant difference (P < 0.001). ICG-iv, Indocyanine green intravenous administration; I-D, Inflation-deflation; STAS, Spread through air spaces.
