Application of three-dimensional contrast-enhanced ultrasonography in evaluating origin of segment IV feeding artery in living liver donors

Abstract

Objective To assess the value of three-dimensional contrast-enhanced ultrasound (3D-CEUS) in evaluation origin of segment Ⅳ feeding artery in living liver donors. Methods 3D-CEUS were used to examine 20 living liver donors. The origin of segment Ⅳ feeding artery were evaluated by two radiologists who blinded to other imaging information. The findings obtained on operation and (or) CTA were used as the reference standard. Results Segment Ⅳ feeding artery originating from left artery, both left and right artery, proper hepatic artery were demonstrated on 3D-CEUS in 13, 1 and 2 patients,respectively. 3D-CEUS accurately depicted the origin of segment Ⅳ feeding artery in 16(80%) patiens.Conclusions 3D-CEUS could be a useful method to demonstrate the origin of segment Ⅳ feeding artery in preoperative evaluation for LDLT.
