Portal Vein Flow by Doppler Ultrasonography and Liver Volume by Computed Tomography in Living Donor Candidates: Correlation with Indocyanine Green Test

Abstract

OBJECTIVES: Our goal was to investigate the correlation between indocyanine green test results and imaging parameters in living liver donor candidates.

MATERIALS AND METHODS: Our study included 219 healthy donor candidates who were evaluated with Doppler ultrasonography (portal vein time average flow), computed tomography (liver volume), liver biopsy (fat fraction), and indocyanine green retention rate at 15 minutes.

RESULTS: Portal vein time average flow (r= -0.375), fat-free liver volume/body weight ratio (r = -0.239), and portal vein time average flow × fat-free liver volume/body weight ratio (r = -0.424) showed significant correlations with indocyanine green retention rate at 15 minutes (all P < .001).

CONCLUSIONS: Imaging parameters were significantly correlated with indocyanine green retention rate at 15 minutes in living liver donor candidates.
