The blood supply of the ano-rectum has been studied in cadaveric specimens by angiographic methods. The vascular anastomosis between the middle rectal and superior rectal vessels was found to be demonstrable on one side only. There appears to be a midline paucity of vessels in both the posterior and anterior rectal walls, and this may be important in the aetiology of anastomotic dehiscence in low anterior resection.
通过血管造影方法对尸体标本的肛管直肠血液供应进行了研究。发现直肠中动脉和直肠上动脉之间的血管吻合仅在一侧可见。直肠前后壁在中线处似乎血管稀少,这在低位前切除术吻合口裂开的病因学中可能很重要。
