正常肠系膜


可见由肠系膜固着的肠袢。注意肠静脉分布,动脉经由同一区域。这样,有一广泛的动脉网向肠供血,使其很难梗死。同样,广泛的静脉管道汇合成门静脉入肝。
Seen here is a loop of bowel attached via the mesentery. Note the extent of the veins. Arteries run in the same location. Thus, there is an extensive anastomosing arterial blood supply to the bowel, making it more difficult to infarct. Also, the extensive venous drainage is incorporated into the portal venous system heading to the liver.
