目的:为患有肝病的直肠癌的外科治疗提供解剖学基础。方法:在20具患有肝脏疾病的成人尸体上解剖观测骶静脉丛的组成及结构特点。结果:①骶静脉丛吻合丰富,呈网状弯曲如蚓。②管壁薄,管腔大、充盈扩张,缺乏静脉瓣。③骶静脉丛与直肠静脉丛、骶管椎内静脉丛有直接交通。结论:。本研究结果为直肠癌根治术的开展提供解剖学基础与参考数据。
Objective: To provide an anatomical basis for the surgical treatment of rectal cancer with liver disease. METHODS: The composition and structure of the sacral venous plexus were dissected from 20 adult cadavers with liver disease. Results: ① sacral venous plexus rich in anastomosis, such as reticular bending earthworm. ② thin wall, large lumen, filling expansion, the lack of venous valve. ③ sacral venous plexus and rectocele, sacral vertebral venous plexus has direct traffic. in conclusion:. The results of this study provide anatomical basis and reference data for the development of radical resection of rectal cancer.
