Résumé
Objective To study the anatomical structure and the distribution of the right posterior sectional Glissonean pedicle so as to provide the anatomical basis for liver resection of the right posterior section.Method By studying the morphological features of the right posterior sectional Glissonean pedicle through peeling and dissecting 20 adult corpses without liver pathological.Result In 95％ of the right posterior sectional Glissonean pedicles there were shared branches.The angle between the GRL/GRA was 81.4° ± 13.8°.In 30％,the right posterior sectional Glissonean pedicle presented as a Y or a V.In a Y shaped,the angle between G6/G7 was 71 ° ±3.92°.The shapes of 70％ of the right posterior sectional Glissonean pedicle presented as a C.The number of branches at the tertiary level was between 3-8.Conclusion The distribution of the right posterior sectional of the Glissonean pedicle did not entirely fit the description of Couinaud's segments.Obvious individual differences existed.Under this circumstance,understanding the anatomy of the right posterior sectional Glissonean pedicle before carrying out partial hepatectomy would be helpful in reducing surgical risks and postoperative complications.
