The origins of historical terms, such as "Arc of Riolan" and "marginal artery of Drummond" are traced herein with emphasis on the inherent confusion caused when these terms are used. Basic mesenteric anatomy is briefly mentioned and pathologic anatomy with its altered direction of blood flow induced by atherosclerosis is stressed. The significance of the meandering mesenteric artery as the main collateral vessel between the superior and inferior mesenteric artery is emphasized along with preoperative and intraoperative ways to ascertain whether or not the origin of this latter vessel can be safely ligated. Specific operations, such as abdominal aortic aneurysmorrhaphy and sigmoid colectomy, which can potentially interfere with blood flow in the meandering mesenteric artery, are discussed in an attempt to prevent postoperative necrosis of any portion of the intestine that may have deficient mesenteric blood flow.
本文追溯了“里罗兰弓”和“德拉蒙德边缘动脉”等历史术语的起源，重点强调了使用这些术语时所产生的内在混淆。简要提及了肠系膜的基本解剖结构，并着重阐述了动脉粥样硬化导致血流方向改变的病理解剖结构。强调了蜿蜒肠系膜动脉作为肠系膜上动脉和肠系膜下动脉之间主要侧支血管的重要性，以及术前和术中确定该血管起源能否安全结扎的方法。还讨论了诸如腹主动脉瘤修补术和乙状结肠切除术等可能会干扰蜿蜒肠系膜动脉血流的特定手术，旨在防止肠系膜血流不足的肠段术后发生坏死。
