【摘要】 目的 了解结肠缘动脉的分支及分布。方法 在70例经动脉灌注红色乳胶的成年人尸体上,解剖观察了由肠系膜上、下动脉所形成的缘动脉。结果 缘动脉的形态不完全相同,各动脉分出的升降支或左右支长短不一,吻合位置也不完全相同,吻合处的血管外径也不完全相同。结论 通过对缘动脉的起源与分支情况的观察,使我们了解缘动脉分布到肠壁的情况。为其临床应用提供解剖学基础。更多还原

【Abstract】 Objective Knowing about the branches of colons of marginal artery and their distributions. Methods The marginal arteries formed by superior & inferior mesenteric arteries were investigated in this study on 70 adult bodies,which were injected red emulsion via arteries. Resutls The shapes of marginal arteries are not completely the same. The ascending and desending branches or the left and right branches from the arteries are different lengths Their anastomotic place and the lateral ridus of the blood vessels in the anastomotic place are different. Conclusion Through observations on the origins and branches of maginal arteries,we know how marginal arteries spread to the intestinal walls. This result provided anatomical basis for clinical applicaton.更多还原
