患有肝脏疾病成人骶静脉丛的解剖及临床意义

Anatomical Study of Sacral Venous Plexusin Patients with Liver Illness

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 the anatomical basis for surgical treatment of rectal cance. Methods:Composition and structural character of sacral venous plexus of 20 adult cadavers who suffered from liver illness were anatomied, observed and measured. Results:①The branches of sacral veniplex shaped like earthworm and anastomosed to nets. ②The branches had thin wall and large cavity but had no valves. ③The sacral veniplex had direct communication with rectal veniplex and introsacral canal veniplex.Conclusion:The results and data can be of use for the sugery treatment of rectal cancer.
