摘要
目的：为骶前手术减少出血提供形态学资料。方法：用解剖和血管透明法观察成人５０例标本的骶前静脉配布。结果：骶中静脉以１支多见，占７６．０％，在骶骨前位置不恒定，骶中静脉有属支与直肠静脉丛、椎内静脉丛及骶外侧静脉吻合。骶外侧静脉以２支多见，占７０．０％，其属支与骶中静脉属支在骶骨前形成水平状吻合，左侧５．８２±０．３２支、右侧５．３７±０．４１支。结论：在作骶前手术尤其直肠切除术时，应特别注意骶前静脉的配布情况，以避免骶前出血。
Objective:To provide morphology basis for anterior sacral operation.Methods: On 50 human cadavers,the anterior sacral veins were observed by dissection and clearing methods.Results:In 76.0% of the cases,the middle sacral vein was single and assumed an inconstant location.Its tributaries may communicate with the rectal venous plexus,the internal vertebral venous plexus and the lateral sacral veins.In 70.0% of the cases,the lateral sacral veins were double on each side.The tributaries of the lateral sacral veins may anastomose with those of the middle sacral vein on the ventral surface of the sacral vertebrae.The numbers of the transverse anastomoses were 5.82±0.32 on the left and 5.37±0.41 on the right.Conclusions: To avoid massive hemorrage during anterior sacral operation.particularly in rectectomy,attention should be paid to the distribution of anterior sacral veins.
