Introduction : The Glission pedicle of anterior section is complexity and there was no detailed description on patterns of the 3rd order of Glission branch. This presentation is attempt to describe the patterns of the 3rd order of Glission branch in right anterior sectionwith SYNAPSE VINCENT 3D and present two video clip of segmentectomy 8 which applied with SYNAPSE VINCENT 3D for preoperative evaluation.

Methods : A total of 106 preoperative multi detector-row computed tomography (MDCT) images were obtained from the donors of adult living donor liver transplantation and the 3D images were reconstructed by SYNAPSE VINCENT medical imaging system. The patterns of the 3rd order of Glission branch in right anterior section were investigated using SYNAPSE VINCENT medical imaging system.

Results : After analysis the patterns of the 3rd order of anterior Glission pedicle, we classified the right anterior Glission pedicle into four types. Type A: cranial-caudal type (49 cases, 46.2%); Type B: ventral-dorsal type (14 cases, 13.2%); Type C: Radial type (37 cases, 34.9%); Type D: The right anterior Glission pedicles have sliding branch to/from posterior branch (6 cases, 5.7%). Two video clip of segmentectomy 8 will be shown. The dye injection and Glissionian technique were applied seperatively and the procedure were evaluate by preoperative SYNAPSE VINCENT 3D.

Conclusions : The detailed description of the 3rd branch of anterior Glission pedicle enriched our understanding of Couinaud segmental anatomy. Preoperative SYNAPSE VINCENT 3D is helpful for anatomic evaluation of liver resection especially segmentectomy.
