本文采用灌注、解剖剥离方法对46具胎儿、2具儿童尸体骶中支数、起始类型、汇入部位、行径及其属支在骶前的分布等进行了观察。并就骶中静脉的临床意义进行了探讨。在直肠切除术中,沿直肠固有筋膜及骶前筋膜之间游离直肠后壁是预防骶前出血的关键。
In this paper, perfused and dissected dissection methods were used to observe the number of sacral midrib, the initial type, the site of entry, the pathology and the distribution of their branches in the presacral region of 46 fetuses and 2 children. And the clinical significance of the sacral vein was discussed. In rectal resection, the free rectal wall along the inherent rectal fascia and presacral fascia is the key to preventing pre-sacral hemorrhage.
